Chief Justice TOAL.
This case involves a contest over the private adoption of a child born in Oklahoma to unwed parents, one of whom is a member of the Cherokee Nation. After a four day hearing in September 2011, the family court issued a final order on November 25, 2011, denying the adoption and requiring the adoptive parents to transfer the child to her biological father. The transfer of custody took place in Charleston, South Carolina, on December 31, 2011, and the child now resides with her biological father and his parents in Oklahoma. We affirm the decision of the family court denying the adoption and awarding custody to the biological father.
[630]*630Facts/Procedural History
Father and Mother are the biological parents of a child born in Oklahoma on September 15, 2009 (“Baby Girl”). Father and Mother became engaged to be married in December 2008, and Mother informed Father that she was pregnant in January 2009.1 At the time Mother became pregnant, Father was actively serving in the United States Army and stationed at Fort Sill, Oklahoma, approximately four hours away from his hometown of Bartlesville, Oklahoma, where his parents and Mother resided.2 Upon learning Mother was pregnant, Father began pressing Mother to get married sooner.3 The couple continued to speak by phone daily, but by April 2009, the relationship had become strained. Mother testified she ultimately broke off the engagement in May via text message because Father was pressuring her to get married. At this point, Mother cut off all contact with Father. While Father testified his post-breakup attempts to call and text message Mother went unanswered, it appears from the Record Father did not make any meaningful attempts to contact her.
It is undisputed that Mother and Father did not live together prior to the baby’s birth and that Father did not support Mother financially for pregnancy related expenses, even though he had the ability to provide some degree of financial [631]*631assistance to Mother.4
In June 2009, Mother sent a text message to Father asking if he would rather pay child support or surrender his parental rights. Father responded via text message that he would relinquish his rights, but testified that he believed he was relinquishing his rights to Mother. Father explained: “In my mind I thought that if I would do that I’d be able to give her time to think about this and possibly maybe we would get back together and continue what we had started.” However, under cross-examination Father admitted that his behavior was not conducive to being a father. Mother never informed Father that she intended to place the baby up for adoption. Father insists that, had he known this, he would have never considered relinquishing his rights.
Mother testified she chose the adoption route because she already had two children by another father, and she was struggling financially. In June 2009, Mother connected with Appellants (or “Adoptive Mother” or “Adoptive Father”) through the Nightlight Christian Adoption Agency (the “Nightlight Agency”). She testified she chose them to be the parents of the child because “[t]hey’re stable____ they’re a mother and father that live inside a home where she can look up to them and they can give her everything she needs when needed.”
Appellants reside in Charleston, South Carolina, and were married on December 10, 2005. Adoptive Mother has a Master’s Degree and a Ph.D. in developmental psychology and develops therapy programs for children with behavior problems and their families. Adoptive Father is an automotive body technician currently working for Boeing. They have no other children. After connecting, Mother spoke with Appellants weekly by telephone, and Adoptive Mother visited Mother in Oklahoma in August 2009. Appellants provided financial assistance to Mother during the final months of her pregnancy and after Baby Girl’s birth. Adoptive Mother testified Mother [632]*632consistently represented that the birth father was not involved.
Mother testified that she knew “from the beginning” that Father was a registered member of the Cherokee Nation, and that she deemed this information “important” throughout the adoption process.5 Further, she testified she knew that if the Cherokee Nation were alerted to Baby Girl’s status as an Indian child, “some things were going to come into effect, but [she] wasn’t for [sic] sure what.” Mother reported Father’s Indian heritage on the Nightlight Agency’s adoption form and testified she made Father’s Indian heritage known to Appellants and every agency involved in the adoption. However, it appears that there were some efforts to conceal his Indian status. In fact, the pre-placement form reflects Mother’s reluctance to share this information:
Initially the birth mother did not wish to identify the father, said she wanted to keep things low-key as possible for the [Appellants], because he’s registered in the Cherokee tribe. It was determined that naming him would be detrimental to the adoption.
Appellants hired an attorney to represent Mother’s interests during the adoption. Mother told her attorney that Father had Cherokee Indian heritage. Based on this information, Mother’s attorney wrote a letter, dated August 21, 2009, to the Child Welfare Division of the Cherokee Nation to inquire about Father’s status as an enrolled Cherokee Indian. The letter stated that Father was “1/8 Cherokee, supposedly enrolled,” but misspelled Father’s first name as “Dustm” instead of “Duste7^ ” and misrepresented his birthdate. (emphasis added).
Because of these inaccuracies, the Cherokee Nation responded with a letter stating that the tribe could not verify Father’s membership in the tribal records, but that “[a]ny incorrect or omitted family documentation could invalidate this determination.” Mother testified she told her attorney that the letter was incorrect and that Father was an enrolled member, but that she did not know his correct birthdate. Adoptive Mother testified that, because they hired an attorney [633]*633to specifically inquire about the baby’s Cherokee Indian status, “when she was born, we were under the impression that she was not Cherokee.”6 Any information Appellants had about Father came from Mother.
When Mother arrived at the hospital to give birth, she requested to be placed on “strictly no report” status, meaning that if anyone called to inquire about her presence in the hospital, the hospital would report her as not admitted.7 Mother testified that neither Father nor his parents contacted her while she was in the hospital.
Adoptive Mother and Adoptive Father were in the delivery room when Mother gave birth to Baby Girl on September 15, 2009. Adoptive Father cut the umbilical cord. The next morning, Mother signed forms relinquishing her parental rights and consenting to the adoption.
Appellants were required to receive consent from the State of Oklahoma pursuant to the Oklahoma Interstate Compact on Placement of Children (“ICPC”) as a prerequisite to removing Baby Girl from that state. Mother signed the necessary documentation, which reported Baby Girl’s ethnicity as “Hispanic” instead of “Native American.” After Baby Girl was discharged from the hospital, Appellants remained in Oklahoma with Baby Girl for approximately eight days until they received ICPC approval, at which point they took Baby Girl to South Carolina. According to the testimony of Tiffany Dunaway, a Child Welfare Specialist with the Cherokee Nation, had the Cherokee Nation known about Baby Girl’s Native American heritage, Appellants would not have been able to remove Baby Girl from Oklahoma.8
[634]*634Father was aware of Mother’s expected due date, but made no attempt to contact or support Mother directly in the months following Baby Girl’s birth.9
Appellants filed the adoption action in South Carolina on September 18, 2009, three days after Baby Girl’s birth, but did not serve or otherwise notify Father of the adoption action until January 6, 2010, approximately four months after Baby Girl was born and days before Father was scheduled to deploy to Iraq. On that date outside of a mall near his base, a process server presented Father with legal papers entitled “Acceptance of Service and Answer of Defendant,” which stated he was not contesting the adoption of Baby Girl and that he waived the thirty day waiting period and notice of the hearing. Father testified he believed he was relinquishing his rights to Mother and did not realize he consented to Baby Girl’s adoption by another family until after he signed the papers. Upon realizing that Mother had relinquished her rights to Appellants, Father testified, “I then tried to grab the paper up. [The process server] told me that I could not grab that [sic] because ... I would be going to jail if I was to do any harm to the paper.”
After consulting with his parents and a JAG lawyer at his base, Father contacted a lawyer the next day, and on January 11, 2010, he requested a stay of the adoption proceedings under the Servicemember’s Civil Relief Act (“SCRA”). On January 14, 2010, Father filed a summons and complaint in an Oklahoma district court to establish paternity, child custody, and support of Baby Girl. The complaint named Appellants and Mother as defendants.10 Paragraph 12 of this Complaint [635]*635stated, “Neither parent nor the children have Native American blood. Therefore the Federal Indian Child Welfare Act ... and the Oklahoma Indian Child Welfare Act ... do not apply.” Father departed for Iraq on January 18, 2010, with his father acting as power of attorney while he was deployed overseas.11
On March 16, 2010, Appellants, with Mother joining, filed a Special Appearance and Motion to Dismiss Father’s Oklahoma action on jurisdictional grounds. The motion was granted, thereby ending the Oklahoma custody action.
Meanwhile, in January 2010, the Cherokee Nation first identified Father as a registered member and determined that Baby Girl was an “Indian Child,” as defined under the Federal Indian Child Welfare Act, 25 U.S.C. § 1901, et seq. (the “ICWA”). It is not apparent from the Record when Appellants were made aware of this change, but on March 30, 2010, Appellants amended their South Carolina pleadings to acknowledge Father’s membership in the Cherokee Nation. Accordingly, on April 7, 2010, the Cherokee Nation filed a Notice of Intervention in the South Carolina action.12
On May 6, 2010, the family court ordered paternity testing which conclusively established Father as the biological father of Baby Girl, and Appellants have since acknowledged Father’s paternity. Furthermore, the family court issued an order confirming venue and jurisdiction in Charleston County Family Court and lifting the automatic stay of proceedings under the SCRA. On May 25, 2010, Father answered Appellants’ amended complaint, stating he did not consent to the adoption of Baby Girl and seeking custody. By temporary order dated July 12, 2011, the family court set a hearing date for the case, and found separately that the ICWA applied to the case.
The trial of the case took place from September 12-15, 2011. A Guardian ad Litem (“GAL”) represented the interests of [636]*636Baby Girl. On November 25, 2011, the family court judge issued a Final Order, finding that: (1) the ICWA applied and it was not unconstitutional; (2) the “Existing Indian Family” doctrine was inapplicable as an exception to the application of the ICWA in this case in accordance with the clear modern trend; (3) Father did not voluntarily consent to the termination of his parental rights or the adoption; and (4) Appellants failed to prove by clear and convincing evidence that Father’s parental rights should be terminated or that granting custody of Baby Girl to Father would likely result in serious emotional or physical damage to Baby Girl. Therefore, the family court denied Appellants’ petition for adoption and ordered the transfer of custody of Baby Girl to Father on December 28, 2011.
Appellants filed a motion to stay the transfer and to reconsider on December 9, 2011, which the family court denied on December 14, 2011.13 Appellants then filed a notice of appeal in the court of appeals on December 20, 2011, along with a petition for a writ of supersedeas. Judge Aphrodite Konduras temporarily granted the petition for a writ of supersedeas pending the filing of a return by Father. On December 30, 2011, Judge Konduras issued an order lifting the temporary grant of supersedeas and denying the petition for a writ of supersedeas. On December 31, 2011, Appellants transferred Baby Girl to Father, and Father and his parents immediately traveled with Baby Girl back to Oklahoma.
This Court certified the appeal pursuant to Rule 204(b), SCACR. In addition to briefs filed by the parties, the American Academy of Adoption Attorneys, the Catawba Indian Nation, the North American Council on Adoptable Children, the Child Welfare League of America, the National Indian Child Welfare Association, and the Association on American Indian Affairs have filed briefs as amici curiae.
Issues
I. Whether Appellants properly transferred Baby Girl to South Carolina.
[637]*637II. Whether the ICWA defers to state law in determining whether an unwed father is a “parent” as defined by the ICWA.
III. Whether Appellants proved grounds to terminate Father’s parental rights under the ICWA.
Standard of Review
When reviewing a decision by the family court, an appellate court has the authority to find the facts in accordance with its own view of the preponderance of the evidence. Lewis v. Lewis, 392 S.C. 381, 384, 709 S.E.2d 650, 651 (2011). “However, this broad scope of review does not require this Court to disregard the findings of the family court” judge who is in a superior position to make credibility determinations, nor does it relieve an appellant of demonstrating the error of the family court. Id. at 384, 389, 709 S.E.2d at 651, 654.
Law/Analysis
I. The ICWA
This case is unique in that it involves an Indian child,14 and thus, any child custody proceeding must be decided within the parameters of the ICWA, 25 U.S.C. § 1901-1963 (1978).
The ICWA “was the product of rising concern in the mid-1970’s over the consequences to Indian children, Indian families, and Indian tribes of abusive child welfare practices that resulted in the separation of large numbers of Indian children from their families and tribes through adoption or foster care placement, usually in non-Indian homes.” Miss. Band of Choctaw Indians v. Holyfield, 490 U.S. 30, 32, 109 S.Ct. 1597, 104 L.Ed.2d 29 (1989). The evidence presented to Congress during the 1974 hearings revealed that “25 to 35% of all Indian children had been separated from their families and placed in adoptive families, foster care, or institutions.” Id. (citation omitted). Moreover, “[t]he adoption rate of Indian children was eight times that of non-Indian children” and “[ajpproxi[638]*638mately 90% of the Indian placements were in non-Indian homes.” Id. at 33, 109 S.Ct. 1597 (citation omitted). At the Congressional hearings, a Tribal Chief described the primary reason for such removal as follows:
One of the most serious failings of the present system is that Indian children are removed from the custody of their natural parents by nontribal government authorities who have no basis for intelligently evaluating the cultural and social premises underlying Indian home life and childrearing. Many of the individuals who decide the fate of our children are at best ignorant of our cultural values, and at worst contemptful of the Indian way and convinced that removal, usually to a non-Indian household or institution, can only benefit an Indian child.
Id. at 34, 35,109 S.Ct. 1597 (citation and footnote omitted).15
Although Congress primarily sought to prevent the involuntary removal of American Indian or Alaska Native Indian children from their families and tribal communities and placement of these children into both foster care and adoptive placements, see 25 U.S.C. §§ 1912(e)-(f), 1915(b), it is clear that Congress was likewise concerned with the voluntary adoptions of Indian children. See 25 U.S.C. § 1915(a) '(“In any adoptive placement of an Indian child under State law, a preference shall be given, in the absence of good cause to the contrary, to a placement with (1) a member of the child’s extended family; (2) other members of the Indian child’s tribe; or (3) other Indian families.” (emphasis added)).
Aside from the avoidance of culturally inappropriate removal of Indian children, Congress intended the ICWA to pre[639]*639serve tribal sovereignty with respect to its familial affairs. In Mississippi Band of Choctaw Indians v. Holyfield, 490 U.S. 30, 32, 109 S.Ct 1597, 104 L.Ed.2d 29 (1989), the only United States Supreme Court case addressing the ICWA, the Court determined that the Choctaw Indian Tribe had the sole authority to determine the adoptive placement of twin babies under the ICWA. In that case, both Indian parents desired to have their twin babies adopted by non-Indian parents. Id. In construing section 1911(a) of the ICWA, the Supreme Court stated:
[n]or can the result be any different simply because the twins were “voluntarily surrendered” by their mother. Tribal jurisdiction under § 1911(a) was not meant to be defeated by the actions of individual members of the tribe, for Congress was concerned not solely about the interests of Indian children and families, but also about the impact on the tribes themselves of the large numbers of Indian children adopted by non-Indians. The numerous prerogatives accorded the tribes through the ICWA’s substantive provisions ... must, accordingly, be seen as a means of protecting not only the interests of individual Indian children and families, but also of the tribes themselves.
Id. at 49, 109 S.Ct. 1597 (internal citations and footnote omitted).16
[640]*640Therefore, exercising its power under the Indian Commerce Clause of the United States Constitution, U.S. Const, art. 1, § 8, Congress passed the ICWA making, inter alia, these specific findings:
(3) that there is no resource that is more vital to the continued existence and integrity of Indian tribes than their children and that the United States has a direct interest, as trustee, in protecting Indian children who are members of or are eligible for membership in an Indian tribe;
(4) that an alarmingly high percentage of Indian families are broken up by the removal, often unwarranted, of their children from them by nontribal public and private agencies and that an alarmingly high percentage of such children are placed in non-Indian foster and adoptive homes and institutions; and
(5) that the States, exercising their recognized jurisdiction over Indian child custody proceedings through administrative and judicial bodies, have often failed to recognize the essential tribal relations of Indian people and the cultural and social standards prevailing in Indian communities and families.
25 U.S.C. § 1901.
Additionally, Congress declared:
[I]t is the policy of this Nation to protect the best interests of Indian children and to promote the stability and security of Indian tribes and families by the establishment of minimum Federal standards for the removal of Indian children from their families and the placement of such children in foster or adoptive homes which will reflect the unique values of Indian culture, and by providing for assistance to Indian tribes in the operation of child and family service programs.
Id. § 1902.17
Because the ICWA establishes “minimum Federal standards for the removal of Indian children from their families” [641]*641and applies to any child custody proceeding involving an Indian child, see 25 U.S.C. §§ 1902, 1903, 1911, it is through this lens that we are constrained to decide the present controversy.
IL Transfer of Baby Girl to South Carolina
In its rendering of the facts of the case, the final order of the family court stated that if it were not for the misinformation provided to the Cherokee Nation about the birth father during the process of securing the ICPC, “[Appellants] [would not have] received permission to remove the child from Oklahoma and transport the child to their home state of South Carolina just days after her birth.” This statement was neither a finding of fact nor a conclusion of law, but rather was part of the factual background provided in the order. Nevertheless, on appeal Respondents argue that South Carolina courts lack jurisdiction to determine the custody issues. In response, Appellants argue that they properly transferred Baby Girl to South Carolina, and if not, the improper transfer was forgivable or understandable. More specifically, Appellants contend the ICPC form, which did not accurately represent Baby Girl’s Indian heritage, should not be construed against them because the ICPC does not protect the rights of birth parents but is designed to ensure the child’s safe transfer across state lines. Thus, Appellants maintain, they have satisfied the requirements of the ICPC by providing Baby Girl with a safe and loving home. Furthermore, while Appellants do not dispute that the Cherokee Nation was never informed of Baby Girl’s status as an Indian child, Appellants argue that [642]*642the misspelling of Father’s name was an obvious mistake, which they subsequently corrected by amending their pleadings to allege Father is a Cherokee Indian.
Appellants correctly identify the purpose of the ICPC. See Doe v. Baby Girl, 376 S.C. 267, 284, 657 S.E.2d 455, 464 (2008) (“[W]e note the ICPC was designed to ensure that placements for children across state lines are safe; it was not designed to protect the rights of the birth parents. Certainly, there was no evidence that Baby Girl’s placement with appellants had become unsafe in any way.” (internal citation omitted)). However, we think Appellants’ argument mischaracterizes the family court’s statement. The family court did not find that Appellants violated the ICPC by unsafely transferring Baby Girl across state lines. Rather, Appellants’ mistake when researching Father’s tribal membership coupled with the subsequent omission on the ICPC form, meant that the Cherokee Nation was not properly alerted to Baby Girl’s status as an Indian child; and therefore, the tribe’s right to participate in Baby Girl’s placement was never triggered before Appellants removed Baby Girl from Oklahoma.
While the evidence establishes Baby Girl would not be in South Carolina had the Cherokee Nation been properly noticed of her status as an Indian child, we agree with Appellants that the propriety of Baby Girl’s transfer to South Carolina was litigated in the Oklahoma action when the Oklahoma court issued an order dismissing the case on jurisdictional grounds. Appellants correctly point out that in Father’s Response to Appellants’ Motion to Dismiss, he argued that the ICPC request form “would not have been processed by Michael Nomura of Heritage Family Services without giving notice to the Cherokee Nation had Defendant not withheld the fact that the baby was part American Indian on the form.” After considering this and other arguments, the Oklahoma court issued an order dismissing the action on jurisdictional grounds, and neither Father nor the Cherokee Nation appealed that order. Therefore, because no appeal was taken from the dismissal of the action, that decision remains the law of the case. See Ulmer v. Ulmer, 369 S.C. 486, 490, 632 S.E.2d 858, 861 (2006) (“A portion of a judgment that is not appealed presents no issue for determination by the reviewing court and constitutes, rightly or wrongly, the law of the case.”).
[643]*643Because the Oklahoma court declined to exercise jurisdiction in this case, it is now incumbent on this Court to resolve the myriad issues concerning Baby Girl’s final placement.
III. Father’s Status as a “Parent” under the ICWA
Appellants claim Father does not have standing to invoke the protection of the ICWA because Father does not meet the ICWA’s statutory definition of “parent” found in section 1903(9).18 We disagree.
The family court found the ICWA was applicable, in that the Cherokee Nation is an “Indian Tribe,” Baby Girl is an “Indian Child,” and Father is a “parent” as prescribed in the ICWA. See 25 U.S.C. § 1903(4), (8)-(9).
The ICWA defines “parent” as
any biological parent or parents of an Indian child or any Indian person who has lawfully adopted an Indian child, including adoptions under tribal law or custom. It does not include the unwed father where paternity has not been acknowledged or established.
Id. § 1903(9) (emphasis added).
Appellants argue that unwed fathers must show more than “mere biology” to invoke the protections of the ICWA. The ICWA does not explicitly set forth a procedure for an unwed father to acknowledge or establish paternity; thus, Appellants argue that the ICWA defers to state law on this point. Relying on section 63-9-310(A)(5) of the South Carolina Code,19 Appellants contend that because Father neither lived with Mother for a continuous period of six months before the [644]*644child’s birth, nor contributed to her pregnancy-related expenses, Father does not qualify as a “parent” under the ICWA.
In making the determination that Father was a “parent” under the ICWA, the family court focused on the distinction between the requirements for an unwed father to consent to an adoption under state law versus the requirements for an unwed father to establish paternity under the ICWA, and found the “ICWA extends greater rights to the unwed Indian father” than state law. (emphasis added). The family court’s finding and Appellants’ argument collapse the notions of paternity and consent. However, the family court ultimately concluded that Father met the ICWA’s definition of “parent” by both acknowledging his paternity through the pursuit of court proceedings as soon as he realized Baby Girl had been placed up for adoption and establishing his paternity through DNA testing. We agree with the family court that, by its plain terms, this is all that is required under the ICWA. Therefore, Father is a “parent” as defined by the ICWA.
TV Termination of Parental Rights
Because we find Father is a “parent”20 for purposes of the application of the ICWA, we now turn to whether Father’s parental rights should be terminated. While the ICWA incorporates state law termination grounds, it also clearly mandates state courts consider heightened federal requirements to terminate parental rights as to ICWA parents.21
[645]*645
A. Voluntary Termination
While Father’s consent would not have been required under South Carolina law, see S.C.Code Ann. § 63-9-310(A)(5), for a parent to voluntarily relinquish his or her parental rights under the ICWA, his or her
consent shall not be valid unless executed in writing and recorded before a judge of a court of competent jurisdiction and accompanied by the presiding judge’s certificate that the terms and consequences of the consent were fully explained in detail and were fully understood by the parent or Indian custodian. The court shall also certify that either the parent or Indian custodian fully understood the explanation in English or that it was interpreted into a language [646]*646that the parent or Indian custodian understood. Any consent given prior to, or within ten days after, birth of the Indian child shall not be valid.
25 U.S.C. § 1913(a). Moreover, a parent may withdraw his or her consent “for any reason at any time prior to the entry of a final decree of termination or adoption, as the case may be, and the child shall be returned to the parent.” Id. § 1913(c).
It is undisputed that the only consent document Father ever signed was a one-page “Acceptance of Service” stating he was not contesting the adoption, which was purportedly presented for Father’s signature as a prerequisite to the service of a summons and complaint. Thus, Appellants did not follow the clear procedural directives of section 1913(a) in obtaining Father’s consent. Moreover, even if this “consent” was valid under the statute, then Father’s subsequent legal campaign to obtain custody of Baby Girl has rendered any such consent withdrawn. Therefore, neither Father’s signature on the “Acceptance of Service” document, nor his stated intentions to relinquish his rights, were effectual forms of voluntary consent under the ICWA.
B. Involuntary Termination
Thus, we may only grant Appellants’ adoption decree with respect to Father in the absence of his voluntary consent if Appellants can establish grounds for involuntarily terminating Father’s parental rights under state law and the ICWA.
Under the ICWA, in addition to any state law grounds for termination, Appellants must “satisfy the court that active efforts have been made to provide remedial services and rehabilitative programs designed to prevent the breakup of the Indian family and that these efforts have proved unsuccessful.” 25 U.S.C. § 1912(d). Moreover,
No termination of parental rights may be ordered in such proceeding in the absence of a determination, supported by evidence beyond a reasonable doubt, including testimony of qualified expert witnesses, that the continued custody of the [647]*647child by the parent or Indian custodian is likely to result in serious emotional or physical damage to the child.
Id. § 1912(f) (emphasis added).
1. Active Remedial Measures
To effect termination under the ICWA, the parties seeking termination “shall satisfy the court that active efforts have been made to provide remedial services and rehabilitative programs designed to prevent the breakup of the Indian family and that these efforts have proved unsuccessful.” 25 U.S.C. § 1912(d).
Appellants admit that the provision has not been satisfied; however, they seek to avoid the remedial measures requirement by claiming that any efforts to rehabilitate Father would be futile. We find Appellants’ futility argument insufficient to override the clear mandate of section 1912(d) under these facts.
Even assuming the dissent is correct in finding that Father did not want custody of Baby Girl and did not desire to act as a parent to her, straightforward application of the language of section 1912(d) requires that remedial services be offered to address any parenting issues to prevent the breakup of the Indian family — for example, by attempting to stimulate Father’s desire to be a parent or to provide necessary education regarding the role of a parent.22 In this case, far from offering such services, Appellants — perhaps understandably, given the emotionally wrenching circumstances — have actively sought to prevent Father from obtaining custody of Baby Girl since she was four months old. Father, despite some early indications of possible lack of interest in Baby Girl, not only reversed course at an early point but has maintained that course despite this active opposition. Therefore, a finding on these facts that the remedial measures mandated by [648]*648the ICWA may be waived would be an unwarranted substitution of this Court’s preferences for the clear dictates of statutory law.23
2. Likelihood of Serious Emotional or Physical Damage
Section 1912(f) requires a qualified expert to provide evidence satisfying this Court beyond a reasonable doubt “that the continued custody of the child by the parent or Indian custodian is likely to result in serious emotional or physical damage to the child.” The family court applied a clear and convincing standard of review, pursuant to Santosky v. Kramer, 455 U.S. 745, 102 S.Ct. 1388, 71 L.Ed.2d 599 (1982), even [649]*649though the instant case deals with termination of parental rights under the ICWA. While the family court misinterpreted Santosky,24 considering it found Appellants failed to meet even the lower burden, we agree that Appellants have not satisfied their burden of proving that Father’s custody of Baby Girl would result in serious emotional or physical harm to her beyond a reasonable doubt.
The family court admitted the testimony of Dr. Bart Saylor as Appellants’ expert witness to demonstrate the likelihood of damage to Baby Girl if removed from Appellants’ custody. Dr. Saylor, a licensed clinical psychologist and designated forensic psychologist, conducted a bonding evaluation with Appellants and Baby Girl, but had no contact with Father. Dr. Saylor only considered the effect of severing Baby Girl’s bond with Appellants and did not review any information about Father’s capacity to form a loving relationship with Baby Girl. Although Dr. Saylor admitted he did not have specific training in Cherokee child rearing practices, he did not believe knowledge of Indian culture was necessary to evaluate the bonding between Baby Girl and Appellants. Dr. Saylor testified that Appellants and Baby Girl had a very strong bond, and therefore,
I believe that at this point removal from the one and only parents, the secure, the bonded relationship, the one and only that she has with these parents at this age would be very traumatic, would be very disruptive. It could produce depression, anxiety, it could cause disruption in her capacity to form relationships at a later age. It would be extremely stressful to her. It would be taking away everything that she had come to know and count on for her comfort and [650]*650security and replace it with something that would be completely unfamiliar and strange to her.
Dr. Saylor confirmed that he believed beyond a reasonable doubt that Baby Girl’s removal from Appellants would cause serious emotional harm. However, Dr. Saylor agreed that even though a child may have bonded successfully one time, a child can bond again. Finally, he could not say what long-term harm would result from Baby Girl’s removal.
Father’s expert, Tiffany Dunaway, a Child Welfare Specialist with the Cherokee Nation who has worked with between ten and fifteen transitioned children the same age as Baby Girl, conducted a home study on Father’s family while Father was stationed on active duty in Iraq. Dunaway reported that the family home was clean, safe, and appropriate and that there were many acres of land surrounding the home for outdoor play. Based on her interaction with Father’s parents, Dunaway opined, “this child will thrive, I don’t have any doubt. I know we can’t predict the future, but I think that she will be safe____She’ll know who she is and where she came from. She’ll be very loved.” Under cross-examination, Dunaway admitted that some transitioned children have difficulties, especially older children, but testified that these children have thrived overall. Dunaway admitted that she had never met Baby Girl, nor had she witnessed Father interact with a child the same age as Baby Girl. Dunaway’s opinion about the ability of the child to thrive was based on anecdotal experience, and she could not produce any studies to show that transitioned children thrive in the long-term.25
In its final order, the family court noted that Dr. Saylor could not render an opinion about the long-term effects of severing the bond between Appellants and Baby Girl, although he testified that in the short-term it would be very traumatic. [651]*651The family court found persuasive the testimony that Father was a good father who enjoyed a close relationship with his other daughter and Dunaway’s testimony that children around Baby Girl’s age tended to thrive when reunited with their Indian parents. Therefore, the family court concluded that Appellants did not prove that “the child will suffer physical or emotional damage if returned to the custody of her biological father,” and as a result, “the ICWA prohibits termination of his parental rights.”
Appellants argue that section 1912(f) does not require a child to suffer long-term harm. Appellants urge this Court to find severe emotional harm likely based solely on the expected harm of severing Baby Girl’s bond from the only parents she knows.
Initially, we note that the plain language of section 1912(d) requires a showing that the transferee parent’s prospective legal and physical custody is likely to result in serious damage to the Indian child, not that the Indian child’s removal from the custody of the adoptive parents will likely result in emotional damage, which in this case Appellants’ expert admits is likely to be temporary.26
Absent any evidence to the contrary, we hold that Appellants’ reliance on bonding, without more, cannot satisfy their high burden of proving that Father’s custody of Baby Girl would result in serious emotional or physical damage to her. While we are conscious that any separation will cause some degree of pain, we can only conclude from the evidence presented at trial that Father desires to be a parent to Baby [652]*652Girl, and that he and his family have created a safe, loving, and appropriate home for her. Furthermore, Father instituted child custody proceedings when Baby Girl was four months old. See Rick P. v. State, OCS, 109 P.3d 950, 958 (Alaska 2005) (footnote omitted) (“Our cases indicate that a parent’s willingness to resume parental duties does not ‘remedy’ abandonment if this change of heart comes too late for the parent to bond with the child during the critical early phase of the child’s life.”). Because Father intervened at this early point and most of the bonding occurred during the course of this litigation, it should not be a factor that weighs against Father. See Holyfield, 490 U.S. at 53-54, 109 S.Ct. 1597 (1989) (“We are not unaware that over three years have passed since the twin babies were born and placed in the [adoptive] home, and that a court deciding their fate today is not writing on a blank slate in the same way it would have [three years ago]. Three years’ development of family ties cannot be undone, and a separation at this point would doubtless cause considerable pain.... Had the mandate of the ICWA been followed [three years ago], of course, much potential anguish might have been avoided, and in any case the law cannot be applied so as automatically to ‘reward those who obtain custody, whether lawfully or otherwise, and maintain it during any ensuing (and protracted) litigation.’ ” (citation omitted)). Thus, the bonding that occurred during litigation, without more, cannot form the basis for terminating Father’s parental rights.
3. State Statutory Grounds for Termination
Because we have found that Appellants have not met their burden of proof to establish termination under the ICWA, we need not address the grounds for termination elucidated in section 63-7-2570 of the South Carolina Code. See Wilkinson ex rel. Wilkinson v. Palmetto State Transp. Co., 382 S.C. 295, 307, 676 S.E.2d 700, 706 (2009) (appellate court need not discuss remaining issues when determination of prior issue is dispositive).
4. Best Interests of the Child
South Carolina courts have a long history of determining custody disputes based on the “best interests of the child.” See Hooper v. Rockwell, 334 S.C. 281, 295, 513 S.E.2d 358, 366 [653]*653(1999) (“This Court long has tried to decide all matters involving the custody or care of children in ‘light of the fundamental principle that the controlling consideration is the best interests of the child.’ ” (quoting In Re Doran, 129 S.C. 26, 31, 123 S.E. 501, 503 (1924))). This important history is not replaced by the ICWA’s mandate. See In re Welfare of L.N.B.-L., 157 Wash.App. 215, 237 P.3d 944, 965 (2010) (“ICWA’s applicability does not mean that ICWA replaces state law with regard to a child’s best interests.”) Instead, “[w]ell-established principles for deciding custody matters should further [the ICWA’s] goals.” Id. (quoting In re Mahaney, 146 Wash.2d 878, 51 P.3d 776, 785 (2002)).
Where an Indian child’s best interests are at stake, our inquiry into that child’s best interests must also account for his or her status as an Indian, and therefore, we must also inquire into whether the placement is in the best interests of the Indian child. See 25 U.S.C. § 1902 (“The Congress hereby declares that it is the policy of this Nation to protect the best interests of Indian children and to promote the stability and security of Indian tribes and families by the establishment of minimum Federal standards for the removal of Indian children from their families and the placement of such children in foster or adoptive homes which will reflect the unique values of Indian culture, and by providing for assistance to Indian tribes in the operation of child and family service programs.”). In making this determination, the child’s relationship with his or her tribe is an important consideration, as the ICWA is “based on the fundamental assumption that it is in the Indian child’s best interest that its relationship to the tribe be protected.” Holyfield, 490 U.S. at 50 n. 24, 109 S.Ct. 1597 (quoting In re Appeal in Pima Cnty. Juvenile Action No. S-903, 130 Ariz. 202, 635 P.2d 187, 189 (App. 1981)).27 Thus, Baby Girl, as an Indian child, has a strong [654]*654interest in retaining ties to her cultural heritage. See id. at 49-50, 109 S.Ct. 1597 (“In addition, it is clear that Congress’s concern over the placement of Indian children in non-Indian homes was based in part on evidence of the detrimental impact on the children themselves of such placements outside their culture.”).28
The family court order stated, “[w]hen parental rights and the best interests of the child are in conflict, the best interests of the child must prevail. However, in this case, I find no [655]*655conflict between the two.”29 Likewise, we cannot say that Baby Girl’s best interests are not served by the grant of custody to Father, as Appellants have not presented evidence that Baby Girl would not be safe, loved, and cared for if raised by Father and his family. Moreover, in transferring custody to Father and his family, Baby Girl’s familial and tribal ties may be established and maintained in furtherance of the clear purpose of the ICWA, which is to preserve American Indian culture by retaining its children within the tribe. See Holyfield, 490 U.S. at 37, 109 S.Ct. 1597.
C. Preferential Placement
Furthermore, even if we were to terminate Father’s rights, section 1915(a) of the ICWA establishes a hierarchy of preferences for the adoptive placement of an Indian child.30 See 25 U.S.C.1915(a). That section provides: “[i]n any adoptive placement of an Indian child under State law, a preference shall be given, in the absence of good cause to the contrary, to a placement with (1) a member of the child’s extended family; (2) other members of the Indian child’s tribe; or (3) other Indian families.” (emphasis added). While , not binding, the Bureau of Indian Affairs Guidelines concerning good cause state that courts may look to the “request of the biological parents or the child when the child is of sufficient age,” the “extraordinary physical or emotional needs of the child as established by testimony of a qualified expert witness,” and the “unavailability of suitable families for placement after a diligent search has been completed for families meeting the [656]*656preference criteria” when deciding to deviate from the stated preferences. 44 Fed. Reg. 67584, 67954-95 (1979). The party-seeking to deviate from the preferences bears the burden of demonstrating that good cause exists. Id.
From the outset, rather than seek to place Baby Girl within a statutorily preferred home, Mother sought placement in a non-Indian home.31 In our view, the ensuing bond that has formed in the wake of this wrongful placement cannot be relied on by Appellants and the dissent to deviate from the ICWA’s placement preferences.
While the best interests of the child standard is always a guiding consideration when placing a child, any attempt to utilize our state’s best interests of the child standard to eclipse the ICWA’s statutory preferences ignores the fact that the statutory placement preferences and the Indian child’s best interests are not mutually exclusive considerations. Instead, the ICWA presumes that placement within its ambit is in the Indian child’s best interests. See In re C.H., 299 Mont. 62, 997 P.2d 776, 784 (2000) (“[T]he best interests of the child ... is an improper test to use in ICWA cases because the [657]*657ICWA expresses the presumption that it is in an Indian child’s best interests to be placed in accordance with statutory preferences. To allow emotional bonding — a normal and desirable outcome when, as here, a child lives with a foster family for several years — to constitute an ‘extraordinary’ emotional need [comprising good cause to deviate from the preferences] would essentially negate the ICWA presumption.” (emphasis added)). Therefore, “the unfettered exercise of [state] discretion poses a real danger that the ICWA preferences will be overridden upon the slightest evidence favoring alternative placement.” Barbara Ann Atwood, Flashpoints under the Indian Child Welfare Act: Toward a New Understanding of State Comi, Resistance, 51 Emory L.J. 587, 645 (2002). Thus, the bonding that has occurred between Appellants and Baby Girl has not satisfied this Court that custody with Father is against Baby Girl’s best interests. For this reason, under these facts, we cannot say that bonding, standing alone, should form the basis for deviation from the statutory placement preferences.
Conclusion
We do not take lightly the grave interests at stake in this case. However, we are constrained by the law and convinced by the facts that the transfer of custody to Father was required under the law. Adoptive Couple are ideal parents who have exhibited the ability to provide a loving family environment for Baby Girl. Thus, it is with a heavy heart that we affirm the family court order.
Because this case involves an Indian child, the ICWA applies and confers conclusive custodial preference to the Indian parent. All of the rest of our determinations flow from this reality. While we have the highest respect for the deeply felt opinions expressed by the dissent, we simply see this case as one in which the dictates of federal Indian law supersede state law where the adoption and custody of an Indian child is at issue. Father did not consent to Baby Girl’s adoption, and we cannot say beyond a reasonable doubt that custody by him would result in serious emotional or physical harm to Baby Girl. Thus, under the federal standard we cannot terminate Father’s parental rights. For these reasons, we affirm the [658]*658family court’s denial of the adoption decree and transfer of custody to Father.
