Opinion

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v. UNPUBLISHED OPINION MOISEES PEDRO VAUGHAN,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 88146-9-I/2

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. 2 88146-9-I/3

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-day- per-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.
