Parenting plans are designed to provide structure and clarity for co-parents who do their best to manage the task of parenting across two households. However, life is unpredictable, and circumstances often change after a parenting plan is finalized. When this happens, parents may choose either to adapt informally or to seek a formal modification through the courts.
Adapting a parenting plan informally means that both parents agree to changes without involving the courts. For example, if one parent’s work schedule changes, the other parent might agree to adjust pickup times or swap weekends as needed. Informal adaptations can be flexible and quick, especially if co-parents communicate well and trust each other to uphold agreements.
However, informal adaptations carry risks. Because they are not court-ordered, they are not enforceable if disagreements arise later. One parent could decide to revert to the original plan at any time, and the other would have no legal recourse to enforce the agreed-upon changes. Additionally, if disputes emerge, courts will look to the official parenting plan on file — not the informal arrangements made between parents.
Seeking enforceable approval from the courts
Formal modification involves returning to court to request a change to the existing parenting plan. In Washington State and many other jurisdictions, parents must demonstrate a substantial change in circumstances to justify modifying a plan, if one parent contests the change at issue. This could include changes in a parent’s work schedule, relocation, a child’s medical needs or concerns about a parent’s ability to care for their child safely. If both parents agree on a formal change, this standard does not typically apply.
While seeking formal modification can feel burdensome, it provides legal protection. Court-approved changes are enforceable, offering stability for both parents and their child. This approach helps to ensure that both parents’ rights and responsibilities are clear and prevents one parent from unilaterally withdrawing from the agreement later.
