Can custody be modified in Washington State?
May 02, 2025  |  Child Custody

Custody arrangements in Washington are detailed in a court-approved parenting plan. While these plans are designed to be stable, they are not necessarily permanent.

In certain cases, parents may request a modification. When can a parenting plan be changed?

Changes since the initial plan was set

A court will consider changing a custody order if there has been a substantial change in circumstances. This means something significant has happened since the current parenting plan was entered. The change must affect the child or the parenting arrangement in a meaningful way.

Common examples include one parent relocating, a change in the child’s needs or concerns about the child’s safety. The court will also look at whether the proposed change is in the best interests of the child.

Major versus minor changes

There are two types of custody modifications in Washington: major and minor. A major modification involves significant changes, such as switching the child’s primary residence. These requests require a higher legal standard and must show that the change would clearly benefit the child.

A minor modification involves less disruptive changes. These may include adjustments to the visitation schedule or decision-making responsibilities. Minor changes are generally easier to request and approve.

To modify custody, a parent must file a petition to modify the parenting plan. The court will review the request and decide if there is adequate cause to move forward. If so, a hearing may be scheduled, and both parents will have a chance to present their case.

The court’s main focus is always the well-being and stability of the child. If you think a modification is necessary, you should seek legal guidance to strengthen your case.
