COMBS, C.J.:
¶ 1 The essential question before this Court is whether the district court erred by ordering the administrator of a decedent’s estate to timely prepare and file a federal estate tax return for purposes of electing portability of the decedent’s Deceased Spousal Unused Exclusion Amount (DSUE), pursuant to 26 U.S.C.A. § 2010, for the benefit of the decedent’s surviving spouse. We hold that it did not.
I.
FACTS AND PROCEDURAL HISTORY
¶ 2 This cause arises from a dispute concerning the estate of Anne S. Vose (Decedent). Decedent died intestate on January 22, 2016. Appellee C.A. Vose, Jr. (Vose) is her surviving spouse, having married Decedent on June 3, 2006. On May 24, 2006, and prior to their marriage, Vose and Decedent entered into an antenuptial agreement that is relevant to this cause. Appellant Robert E. Lee, III (Lee) is the current administrator of the estate, and also Decedent’s son from a prior marriage.
¶ 3 On January 25, 2016, Lee sought admission to probate of Decedent’s will from 1995 and, in accordance with the will, appointment of himself and his sister as co-administrators of Decedent’s estate. On January 29, 2016, Vose filed his own petition, alleging that Decedent died intestate, asserting a prior right over all Letters of Administration, and seeking to become sole administrator of Decedent’s estate.
¶ 4 Lee eventually withdrew his petition, according to him because of representations from Vose concerning the revocation of Decedent’s 1995 will. He also claims that at that time he had yet to see the antenuptial agreement between Vose and Decedent. The court held a hearing on Vose’s petition on February 23, 2016, where the antenuptial agreement was mentioned but not presented. Vose was appointed administrator of Decedent’s estate and letters were signed. After the antenuptial agreement was produced and Vose’s waiver of the right to be appointed administrator of Decedent’s estate was made manifest, an agreed order was entered appointing Lee as the administrator of Decedent’s estate. '
¶ 5 Lee has filed several applications concerning this matter with the district court. Some have been granted, but many have been stayed pending a conflict of interest hearing concerning Vose’s counsel. Part of the way through the proceedings, three attorneys from McAfee & Taft entered appearances for Vose, and Vose’s previous counsel withdrew. Lee objects to Vose’s new counsel.
¶ 6 On August 10, 2016, Vose filed his Application to Compel Administrator to Timely Prepare and File a Federal Estate Tax Return for Purposes of Irrevocably Electing Portability of Decedent’s Deceased Spousal Unused Exclusion Amount (DSUE Application). The DSUE Application is the primary matter at issue in the order Lee appeals. At a hearing held on August 24, 2016, the district court decided to stay all pending issues in the cause until the alleged conflict of interest issue could be resolved, but stated it would allow the DSUE Application to be heard as scheduled on September 9, 2016, so long as it was presented through special counsel.
¶ 7 On November 8, 2016, the district court entered its order effectively granting Vose’s DSUE application. The district court, non-
exhaustively: 1) denied Vose’s request for appointment of a special administrator for purposes of filing an estate tax return for Decedent; 2) ordered Lee to provide Vose with a list of the records necessary to prepare the estate tax return and ordered Vose to provide the records; 3) ordered Vose to produce to Lee a detailed inventory of the personal property of Decedent in his possession and make it available for pickup; 4) ordered, if a DSUE is available, that the administrator shall timely file an estate tax return electing portability of the DSUE and allow Vose 60 days to review the return and documentation prior to filing; and 5) ordered Vose to pay for the filing of the return if a DSUE is available.
¶ 8 Lee appealed, filing an Amended Petition in Error (with the district court’s order attached) with this Court on November 9, 2016. Vose moved to dismiss the appeal on October 31, 2016, and this Court denied the motion on December 12, 2016. Lee filed a Motion to Retain Appeal and Place on Fast Track Docket on November 23, 2016, and the Court granted the motion and ordered accelerated briefing. The cause was assigned to this office on December 16,2016.
¶ 9 Lee raises several points of error on appeal, including: 1) the district court lacked subject matter jurisdiction; 2) its order concerning the DSUE is preempted by federal law; 3) the trial court failed to properly consider the antenuptial agreement and therefore erroneously determined Vose had standing; 4) the district court’s order violates the terms of the antenuptial agreement.

THE DECEASED SPOUSAL UNUSED EXCLUSION AMOUNT AND PORTABILITY
¶ 11 With the passage of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010, Pub. L. No. 111-312, § 303, 124 Stat. 3296 (2010), a concept known as portability was introduced into the United States Tax Code. The mechanism was made permanent by the American Taxpayer Relief Act of 2012, Pub. L. No. 112-240, 126 Stat. 2313 (2013). In the event a first-to-die spouse has not fully used the estate tax exclusion, portability allows for the unused portion to be transferred to the surviving spouse. DetaOs concerning the mechanics are provided in 26 U.S.C.A. § 2010.
The unused exclusion amount that may be transferred to the surviving spouse is called the Deceased Spousal Unused Exclusion
Amount (DSUE). 26 U.S.C.A. § 2010(c)(4). However, in order for a surviving spouse to make use of the DSUE, an election must be made by the executor of the deceased spouse’s estate, who must also file an estate tax return. Specifically, 26 U.S.C.A. § 2010(c)(5)(A) provides:
(A) Election required.—A deceased spousal unused exclusion amount may not be taken into account by a surviving spouse under paragraph (2) unless the executor of the estate of the deceased spouse files an estate tax return on which such amount is computed and makes an election on such return that such amount may be so taken into account. Such election, once made, shall be irrevocable. No election may be made under this sub-paragraph if such return is filed after the time prescribed by law (including extensions) for filing such return.
¶ 12 The Internal Revenue Service has promulgated rules
concerning portability that further clarify the election process and who may make the election. Specifically, 26 C.F.R. § 20.2010-2 provides in pertinent part:
(6) Persons permitted to make the election—(i) Appointed executor. An executor or administrator of the estate of a decedent survived by a spouse that is ap
pointed, qualified, and acting within the United States, within the meaning of section 2203 (an appointed executor), may timely file the estate tax return on behalf of the estate of the decedent and, in so doing, elect portability of the decedent’s DSUE amount. An appointed executor also may elect not to have portability apply pursuant to paragraph (a)(3) of this section.
(ii) Non-appointed executor. If there is no appointed executor, any person in actual or constructive possession of any property of the decedent (a non-appointed executor) may timely file the estate tax return on behalf of the estate of the decedent and, in so doing, elect portability of the decedent’s DSUE amount, or, by complying with paragraph (a)(3) of this section, may elect not to have portability apply. A portability election made by a non-appointed executor when there is no appointed executor for that decedent’s estate can be superseded by a subsequent contrary election made by an appointed executor of that same decedent’s estate on an estate tax return filed on or before the due date of the return, including extensions actually granted. An election to allow portability made by a non-appointed executor cannot be superseded by a contrary election to have portability not apply made by another non-appointed executor of that same decedent’s estate (unless such other non-appointed executor is the successor of the non-appointed executor who made the election). See § 20.6018-2 for additional rules relating to persons permitted to file the estate tax return.
¶ 13 In its Summary of Comments and Explanation of Revisions, the IRS further clarified why only an executor, and not a surviving spouse who is not an executor (such as Vose in this cause) may make the DSUE portability election. Portability of a Deceased Spousal Unused Exclusion Amount, 80 Fed. Reg. 34,279-01, 34,281 (June 16, 2015). Specifically, the IRS explained:
3. Persons Permitted to Make the Election
Several commenters requested that the final regulations allow a surviving spouse who is not an executor as defined in section 2203 of the Code to file an estate tax return and make the portability election in several different circumstances. A few of the circumstances described include those in which the spouse is given the right to file the estate tax return in a prenuptial or marital agreement, or the spouse has petitioned the appropriate local court for the spouse’s appointment as an executor solely for the limited purpose of filing the estate tax return and the executor does not make the portability election. The Treasury Department and the IRS recognize the possibility that an executor may exercise the executor’s discretion to not make the portability election, thus causing the estate to forfeit the opportunity to elect portability, but note that section 2010(c)(6) of the Code permits only the executor of the decedent’s estate to file the estate tax return and make the portability election. The 2012 temporary regulations address the circumstances in which an appointed executor or a non-appointed executor may file the estate tax return and decide whether or not to elect portability. The Treasury Department and the IRS believe that any consideration of what, if any, state law action might bring the surviving spouse within the definition of executor under section 2203 is outside of the scope of this regulation. Accordingly, the final regulations adopt the applicable rules in the 2012 temporary regulations without change.
Id.
¶ 14 Lee asserts that he is the appointed executor within the meaning of the relevant federal law.
Accordingly, Lee argues on appeal that, pursuant to 26 U.S.C.A. § 2010 and the applicable regulations, the decision to elect portability of the DSUE is discretionary and entirely his to make. He further argues that the district court therefore had no sub
ject matter jurisdiction over the matter, and that its order compelling him to make the election is directly contrary to federal law and any state law grounds on which it might be based are defeated by the preemption doctrine.
IV.
THE DISTRICT COURT PROPERLY EXERCISED AUTHORITY AND SUBJECT MATTER JURISDICTION, UNAFFECTED BY THE PREEMPTION DOCTRINE
A. The district court possesses statutory authority over matters related to probate.
¶ 15 To begin, authority
in probate matters is conferred upon the district courts of Oklahoma by 58 O.S. 2011 § 1.
The district court sitting in probate has the power to order and regulate all distribution of property or estates of deceased persons. Title 58 O.S. 2011 § 1(A)(7). The district court sitting in probate also has the power to cause estate taxes to be equitably apportioned and collected. Title 58 O.S. 2011 § 1(B). Finally, the district court sitting in probate has authority to make all such orders as may be necessary to exercise the powers conferred upon it, 58 O.S. 2011 § 1(A)(10), and further authority to determine rights as to estate property as to all persons and entities. 58 O.S. 2011 § 1(C). Given the statutory authority granted to the district court sitting in probate, it possesses authority to determine the applicability of federal estate tax provisions to Decedent’s estate and determine what interest, if any,
Vose may have in the DSUE. Lee does not dispute this on appeal, but rather argues: 1) the district court is deprived of jurisdiction in this matter by virtue of the preemption doctrine; and 2) Vose is not an heir and has no interest in the estate (and hence no standing) pursuant to the antenuptial agreement he entered into with Decedent prior to their marriage.
B. The preemption doctrine does not bar the district court’s exercise of authority and jurisdiction in this matter.
¶ 16 The preemption doctrine arises from the Supremacy Clause of the United States Constitution. U.S. Const. art. VI, cl. 2.
Though he does not explicitly state it, Lee’s combined argument concerning preemption and lack of subject matter jurisdiction implies he is relying on the concept of complete preemption, which converts what would ordinarily be state law claims into federal claims.
See Devon Energy Production Co., L.P. v. Mosaic Potash Carlsbad, Inc.,
693 F.3d 1195, 1204-1205 (10th Cir. 2012). When a federal statute completely preempts a state-law cause of action, a claim which comes within the scope of that cause of action, even if pleaded in terms of state law, is in reality based on federal law.
Beneficial Nat. Bank v. Anderson,
539 U.S. 1, 2, 123 S.Ct. 2058, 2059, 156 L.Ed.2d 1 (2003).
¶ 17 In
Reeds v. Walker,
this Court noted the link between complete preemption and the potential loss of subject matter jurisdiction:
Although the complete preemption doctrine is ordinarily invoked to support removal of an action to federal court, we see no reason why it cannot be invoked in a state-court appellate proceeding to analyze federal question jurisdiction, which, if exclusive, would divest the state courts of subject matter jurisdiction.
2006 OK 43, ¶ 15 n.34, 157 P.3d 100 (internal citations omitted).
However, complete preemption is a rare doctrine.
Devon Energy Production Co., L.P.,
693 F.3d at 1204; Cmty. State Bank v. Strong, 651 F.3d 1241, 1260 n. 16 (11th Cir. 2011).
The Tenth Circuit explained:
“[w]e read the term [“complete preemption”] not as a crude measure of the breadth of the preemption (in the ordinary sense) of a state law by a federal law, but rather as a description of the specific situation in which a fedei-al law not only preempts a state law to some degree but also substitutes a federal cause of action for the state cause of action, thereby manifesting Congress’s intent to permit removal.”
Devon Energy Production Co., L.P.,
693 F.3d at 1205 (quoting
Schmeling v. NORDAM,
97 F.3d 1336, 1342 (10th Cir. 1996)).
In other words, the federal statute must so pervasively regulate its respective area that it leaves no room for state-law claims.
Devon Energy Production Co., L.P.,
693 F.3d at 1205.
¶ 18 Vose’s claims concerning the DSUE are rooted in Oklahoma law concerning the fiduciary obligations owed by estate administrators to potential beneficiaries of the estate. There is no indication in the federal law provisions concerning the DSUE that the Congress intended to leave no room for state law claims relating to the duties of
the estate administrator, even if those duties involve a federal matter such as the election of the DSUE. Indeed, the IRS itself acknowledged that the question of what state law actions might bring a surviving spouse within the definition of executor pursuant to 26 U.S.C.A. § 2203 are outside the scope of its regulations, implicitly acknowledging the interplay between state laws concerning probate and estate distribution and the federal estate tax provisions. The complete preemption doctrine is inapplicable here and does not deprive the district court of subject matter jurisdiction in this cause.
¶ 19 Absent complete preemption, the question is whether the district court’s order violates any other aspect of the preemption doctrine. This Court has previously stated the ways in which preemption might come into play:
Generally, preemption is a matter of Congressional intent that occurs under four instances: (1) express statutory language; (2) a pervasive regulatory scheme that infers by its presence that Congress felt the federal regulation did not need supplemental state law provisions; (3) an actual conflict between state and federal laws making it physically impossible to comply with both; or (4) where the objectives and purpose of Congress are thwarted by state law.

Missouri-Kansas-Texas R. Co. v. State,
1985 OK 108, ¶ 41, 712 P.2d 40.
The Supreme Court of the United States effectively summarized the doctrine in
Arizona v. U.S.,
where it stated:
... state laws are preempted when they conflict with federal law.

530 U.S. 363],

at 372, 120 S.Ct. 2288 [147 L.Ed.2d 352 (2000)]. This includes cases where “compliance with both federal and state regulations is a physical impossibility,”

373 U.S. 132, 142-143, 83 S.Ct. 1210, 10 L.Ed.2d 248 (1963), and those instances where the challenged state law “stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress,”

Crosby, supra,
at 373, 120 S.Ct. 2288 (“What is a sufficient obstacle is a matter of judgment, to be informed by examining the federal statute as a whole and identifying its purpose and intended effects”). In preemption analysis, courts should assume that “the historic police powers of the States” are not superseded “unless that was the clear and manifest purpose of Congress.”
Rice [v. Santa Fe Elevator Corp.,
331 U.S. 218],
supra,
at 230, 67 S.Ct. 1146 [91 L.Ed. 1447 (1947) ]; see
Wyeth v. Levine,
555 U.S. 555, 565, 129 S.Ct. 1187, 173 L.Ed.2d 51 (2009).
567 U.S. 387, 132 S.Ct. 2492, 2501, 183 L.Ed.2d 351 (2012).
¶20 Lee asserts there is a direct conflict between the district court’s order compelling him to file an estate tax return for Decedent and elect portability of the DSUE for use by Vose, and the terms of 26 U.S.C.A. § 2010, which grants him discretion as to whether or not he will do so. It is this discretion that poses the problem.
¶ 21 However, 26 U.S.C.A § 2010 grants the administrator a choice, and the statute as a whole is silent as to the effect state laws might have on how the administrator must make that choice. Here, the district court ordered Vose to elect portability in response to arguments that his fiduciary obligations as an estate administrator under Oklahoma law compel him to do so. The result, an election of portability, does not directly conflict with 26 U.S.C.A § 2010, which allows such an election. Lee makes no argument that: 1) there is an explicit preemption clause in the Internal Revenue Code in this instance; 2) the regulatory scheme is so pervasive it leaves no room for state law provisions; and 3) it is somehow physically impossible to comply with both laws, for the district court’s order compels him to take an action allowed by federal law. By asserting deprivation of a choice granted by 26 U.S.C.A §2010, he implicates the fourth factor set out by this Court, that the district court’s order thwarts the objective and purpose of Congress.
Todd v. Frank’s Tong Service, Inc.,
1989 OK 121, ¶ 5, 784
P.2d 47.
See Arizona v. U.S,
132 S.Ct. 2492, 2501
¶ 22 The fact that state law may restrict a choice granted by federal law does not necessarily implicate the preemption doctrine by thwarting the objective and purpose of the law. In
Williamson v. Mazda Motor of America, Inc.,
the Supreme Court of tine United States determined that even though a state tort judgment might restrict manufacture choice concerning seat belt installation allowed by federal law, the judgment was not an obstacle to the accomplishment of the full purposes and objectives of federal law because maintaining manufacturer choice was not a significant regulatory objective. 562 U.S. 323, 336, 131 S.Ct. 1131, 1139, 179 L.Ed.2d 75 (2011). Particularly persuasive is Justice Sotomayor’s concurring opinion, where she notes:
In other words, the mere fact that an agency regulation allows manufacturers a choice between options is insufficient to justify implied pre-emption; courts should only find pre-emption where evidence exists that an agency has a regulatory objec
tive—e.g.,
obtaining a mix of passive restraint mechanisms, as in Geier—whose achievement depends on manufacturers having a choice between options.
Williamson,
562 U.S. at 338, 131 S.Ct. 1131 (Sotomayor, J., concurring).
¶ 23 Though the facts are different, the logic is applicable here. Absent an expressed Congressional purpose served by the DSUE election choice, the fact that the choice may be restricted on state law grounds does not implicate preemption. An examination of the relevant provisions does not reveal such a purpose. In fact, the IRS leaves open the possibility that a state court could appoint the surviving spouse as the administrator for the limited purpose of making the election, thereby depriving the primary administrator of the ability to make the election, either to comply with an antenuptial agreement or on some other grounds.
See
Portability of a Deceased Spousal Unused Exclusion Amount, 80 Fed. Reg. 34,279-01, 34,281 (June 16, 2015). It is the conclusion of this Court that the district court’s order compelling Lee to file an estate tax return and elect portability is within the district court’s subject matter jurisdiction and is not preempted by federal law.
V.
THE DISTRICT COURT DID NOT ERR BY ORDERING LEE TO FILE A FEDERAL ESTATE TAX RETURN AND ELECT PORTABILITY OF THE DSUE
¶ 24 Lee asserts Vose lacked standing to press DSUE Application before the district court because he is not an heir and can have no interest in Decedent’s estate pursuant to the antenuptial agreement he entered into with Decedent prior to their marriage. Lee further argues that the district court’s order violates the antenuptial agreement.
A. Vose has standing to assert his interest in the DSUE, independent of any other interest he may have, unless his interest in the DSUE is barred by the antenuptial agreement.
¶ 25 Lee asserts Vose waived his right to a distributive share under Paragraph 6.1(H) of the antenuptial agreement
, and thus is not an heir of Decedent and without standing to press his DSUE application in the district court. Standing in a probate proceeding generally requires a pecuniary interest in the estate of the deceased.
See
58 O.S. 2011 § 29 (interested persons may contest will); 58 O.S. 2011 § 129 (interested persons may contest petition for letters of adminis
tration);
Murg v. Barnsdall Nursing Home,
2005 OK 73, ¶ 20, 123 P.3d 21;
Mayweather v. Wallace,
1945 OK 148, ¶¶ 16-18, 195 Okla. 587, 159 P.2d 529.
¶ 26 However, Vose’s status as an heir and his potential right to an intestate share under 84 O.S. § 213(B), is not the subject of this appeal. Title 26 U.S.C.A. § 2010 grants Vose a potential interest in a part of Decedent’s estate under the control of Lee as the administrator. Vose may have a pecuniary interest as the surviving spouse in the portability of the DSUE, independent of his ability to take as an hem. The portability election would result in an increase to Vose’s own applicable exclusion amount pursuant to 26 U.S.C.A. § 2010(c)(2). If reliance is not placed on any specific statute authorizing invocation of the judicial process, the question of standing depends upon whether the party has alleged a personal stake in the outcome.
Ind. School Dist. No. 9 of Tulsa County v. Glass,
1982 OK 2, ¶ 8, 639 P.2d 1233. Vose has an obvious interest in the portability of the DSUE. The determinative question, then, is not whether the antenuptial agreement between Vose and Decedent bars him from being a legal heir, but whether the agreement bars him from claiming any interest in the portability of the DSUE.
B. Vose’s interest in the DSUE is not barred by the antenuptial agreement he entered into with Decedent.
¶ 27 Antenuptial agreements are contracts. Title 84 O.S. 2011 § 44;
Freeman v. Freeman,
1977 OK 110, ¶¶ 1-2, 565 P.2d 365. Antenuptial agreements can be used to waive rights to property or in other ways alter the rights related to marriage, statutory or otherwise.
See In re Cobb’s Estate,
1956 OK 299, 305 P.2d 1028.
¶28 However, extant applicable law is a part of every contract in this state as if it were expressly cited or its terms incorporated in the contract.

¶ 29 Further, in
Faulkenberry v. Kansas City Southern Ry. Co.,
this Court considered the principles concerning waiver of rights under federal law, and the conclusion reached by the Court is relevant to this cause:
No one can be bound by a waiver of one’s lights unless it was made with full knowledge of the rights intended to be waived. The fact that one knows his rights and intends to waive them must plainly appear. An indispensable ingredient of effective waiver is a freely exercised will to relinquish a known right,
1979 OK 142, ¶ 6, 602 P.2d 203 (footnotes omitted). One must have actual or constructive knowledge of rights to waive them.

1989 OK 8, ¶ 29 n.42, 775 P.2d 766;
Faulkenberry,
1979 OK 142, ¶ 6, 602 P.2d 203.
¶ 30 Given the above principles, the antenuptial agreement does not bar Vose’s interest in the DSUE. The portable DSUE is not simple property acquired by one party over the course of the marriage according to existing laws in effect when the agreement was made. It is an interest created by the federal tax code that was an impossibility at the time the antenuptial agreement between Vose and Decedent was created. The ante-nuptial agreement was entered into on May 24, 2006, and portability of the DSUE became an option under the federal tax code for the first time with the passage of the Tax Relief, Unemployment Insurance Reauthori-zation, and Job Creation Act of 2010, Pub. L. No. 111-312, § 303, 124 Stat. 3296 (2010). Vose and Decedent clearly intended a comprehensive waiver of their marital rights under the law as it existed at the time, and
included reference to specific statutory provisions where necessary. However, the agreement is silent as to portability because the change in law was unforeseeable to the parties when the contract was made. Accordingly, the district court was correct in implicitly determining that the antenuptial agreement did not bar Vose from asserting an interest in portability of the DSUE.
C. Given Lee’s fiduciary obligations as the estate administrator of Decedent under Oklahoma law, the district court did not err by ordering Lee to file an estate tax return and elect portability of the DSUE.
¶ 31 A administrator is responsible for the faithful administration of the estate’s property,
Wilson v. Kane,
1993 OK 65, ¶ 10, 852 P.2d 717, and has a duty to preserve the estate.
Murg v. Barnsdall Nursing Home,

In re Estate of Bleeker,
2007 OK 68, ¶ 13, 168 P.3d 774.
¶ 32 Lee argues that since the DSUE is valuable only to Vose, while at the same time being an estate asset under Lee’s complete control, he should be allowed to demand consideration from Vose in exchange for making the election. Lee further argues that pursuant to 26 U.S.C.A. § 2010(c)(5), electing portability of the DSUE will extend the audit window for Decedent’s estate considerably. While 26 U.S.C.A. § 2010 requires the administrator to make the election to allow portability of the DSUE, the only person with an interest in and ability to use the DSUE, if it exists, is the surviving spouse. If the election is not made through the timely filing of an estate tax return, then it is lost. 26 U.S.C.A. § 2010(c)(5)(A). Vose has also agreed to pay any costs associated with preparing the necessary return.
¶ 33 The district court, after hearing expert testimony and considering the evidence, evidently determined that any risk to the estate was outweighed by Lee’s fiduciary obligation to preserve the assets of the estate and safeguard Vose’s interest in the DSUE. We agree, and determine the district court did not eiT by requiring Lee to file a federal estate tax return and elect portability of the DSUE. The district court’s order was not contrary to the clear weight of the evidence or applicable governing law, and is therefore affirmed. Because of the time sensitive nature of this matter, any potential Petition for Rehearing is to be filed no later than Friday, January 27.
ORDER OF THE DISTRICT COURT IS AFFIRMED; CAUSE REMANDED.
