IN THE COURT OF APPEALS OF THE STATE OF WASHINGTON NANCY YOLANDA ORTIZ- SOSA, No. 88146-9-I
Appellant, DIVISION ONE
v. UNPUBLISHED OPINION MOISEES PEDRO VAUGHAN,
Respondent.
COBURN, J. — Appellant Nancy Ortiz-Sosa appeals a Parenting Plan Order and Final Child Support Order regarding the child she shares with Respondent Moisees Vaughn. Because the trial court failed to enter the statutorily required findings for modification of a parenting plan, we reverse and remand.
FACTS
Appellant Nancy Ortiz-Sosa and Respondent Moisees Vaughn share one child, born in 2020. When the child was 11 months old, in January 2021, Mason County Superior Court entered a parenting plan ordering that the child live with Ortiz-Sosa except for every weekend from Friday evening to Sunday morning, when the child would live with Vaughan. There was no request for child support filed at this time.
In May 2023, Vaughan filed a written petition to modify the parenting plan. He requested only a change to transporting the child between homes because he had moved. The court denied the motion. At the hearing, Vaughan started to also request a change to the parenting plan schedule, but the court informed him that to request a
schedule change he would need to file a new motion. The record before us does not reflect any later motion by Vaughan.
Instead, over a year later, on June 20, 2024, Ortiz-Sosa filed a petition to modify the parenting plan and request child support from Vaughan, apparently for the first time. Ortiz-Sosa proposed that the child live with her except for every other week from Sunday evening to Tuesday morning, when the child would live with Vaughan. 1 In July 2024, Vaughan filed a written response disagreeing with Ortiz-Sosa’s proposed parenting plan and with her request for child support; he stated that he deserved more time with his child.
The parties entered mediation and, on November 14, 2024, reached a written agreement that the child would live with Vaughan every other week from Sunday morning to Thursday morning, with an overnight Wednesday visit on the alternating weeks. The child would live with Ortiz-Sosa the remainder of the time. Vaughan later testified that they followed this mediated schedule for about two and a half months until Ortiz-Sosa stopped following it.
In December 2024, Ortiz-Sosa filed a motion for an adequate cause decision to modify the parenting plan, attaching a declaration stating that she did not agree with the mediation agreement. Ortiz-Sosa eventually proposed that the child live with Vaughan only every other weekend from Saturday morning to Sunday evening.
The same month, Vaughan filed a declaration opposing Ortiz-Sosa’s motion for adequate cause and requesting the court approve the mediated agreement as the
1 Ortiz-Sosa’s proposed parenting plan listed this schedule under “Summer Schedule” on the form, but based on the entirety of the record, including Ortiz-Sosa’s brief on appeal, it appears this was a clerical error and Ortiz-Sosa was in fact proposing this as a year-round schedule.
permanent parenting plan. Vaughan filed a proposed parenting plan proposing the mediated schedule. 2 On December 30, 2024, the court conducted an adequate cause hearing.
Vaughan confirmed he wanted the court to order the mediated parenting plan agreement. Based on this, the court concluded that there was agreement to adequate cause. The court entered a written order stating that the parties agreed there is adequate cause to hold a full hearing.
The trial court conducted a hearing on March 20, 2025. Ortiz-Sosa and Vaughn were both present at the hearing and represented themselves. Ortiz-Sosa testified that she wanted stability for the child, not “bouncing from home to home during the week.” She testified that she worked six days a week to support their child because she was solely financially responsible for the child. 3 She said the child expressed not wanting to go to Vaughan’s home because she did not want to sleep alone there. Vaughan testified that his relationship with the child had grown while spending more time together under the mediated agreement. He felt it was important for the child to know she could rely on him. He explained that he lived five minutes from the child’s school with work flexibility and could thus accommodate her needs. The court undertook colloquies with both
2 “Parties can use stipulations and alternative dispute resolution to create proposed changes to a parenting plan for a trial court to consider. But the trial court must review the parties’ proposed changes under the best interests of the child standard and approve or reject them. RCW 26.09.260(1)… ” Marriage of Coy, 160 Wn. App. 797, 806 n.7, 248 P.3d 1101 (2011). The parties had used mediation to create a proposed modification to their parenting plan, and Vaughan was asking the trial court to approve it under the standards of RCW 26.09.260(1).
3 On appeal, Ortiz-Sosa objects to the trial court’s repeated statement that her six-dayper -week work schedule was her “choice.” We note there is evidence in the record that, in addition to work, Ortiz-Sosa was also attending college full time, had the child living with her the majority of the time, and had only irregular financial support from Vaughan.
parties discussing various potential schedules.
At the conclusion of the hearing, the court entered written parenting plan and child support orders. The parenting plan ordered a 50/50 week on/week off parenting time schedule where the child would spend one full week at a time with each parent, switching homes each Monday. Each week the child would have one after-school visit with the parent whose home she was not staying at. Vaughn was ordered to pay a monthly child support amount of $202 to Ortiz-Sosa. The trial court did not enter any written or oral findings.
Ortiz-Sosa appeals.
DISCUSSION
Modification of Parenting Plan A trial court’s order modifying a parenting plan is reviewed for abuse of discretion. In re Marriage of Kinnan, 131 Wn. App. 738, 746, 129 P.3d 807 (2006). A trial court abuses its discretion if it fails to follow the statutory procedures or modifies a parenting plan for reasons other than the statutory criteria. In re Custody of Halls, 126 Wn. App. 599, 606, 109 P.3d 15 (2005) (citing In re Marriage of Hoseth, 115 Wn. App. 563, 569, 63 P.3d 164 (2003)). “The trial court’s discretion is cabined by several provisions in chapter 26.09 RCW.” In re Marriage of Chandola, 180 Wn.2d 632, 642, 327 P.3d 644 (2014).
Modification of a parenting plan is statutorily prescribed by RCW 26.09.260 and .270. Compliance with the statutory procedures is mandatory. Bower v. Reich, 89 Wn. App. 9, 14, 964 P.2d 359 (1997). As a threshold requirement to obtain a full fact-finding hearing on the issue of modification of a parenting plan, a party must submit with his or
her motion an affidavit listing facts supporting the requested modification. RCW 26.09.270. The court must deny the motion unless it finds that the affidavits establish adequate cause for hearing the motion. RCW 26.09.270.
Once a court finds adequate cause to schedule a parenting plan modification hearing under RCW 26.09.270, the trial court may then modify the existing parenting plan under RCW 26.09.260(1) only if the court makes specific, required findings:
…the court shall not modify a prior custody decree or a parenting plan unless it finds, upon the basis of facts that have arisen since the prior decree or plan or that were unknown to the court at the time of the prior decree or plan, that a substantial change has occurred in the circumstances of the child or the nonmoving party and that the modification is in the best interest of the child and is necessary to serve the best interests of the child.
RCW 26.09.260(1) (emphasis added).
For major modifications such as the modification ordered in this case, RCW 26.09.260(2) establishes a presumption against changing a previously decreed residential schedule:
