When Can You Modify a Parenting Plan?

Washington State allows modifications to parenting plans under certain circumstances. The court will consider changes if there has been a significant change in circumstances or if the current plan is no longer working for the child.

Parenting Plans That Actually Work

A parenting plan should not be vague, emotional or open to endless interpretation. It must be clear, practical, measurable and child-focused.

Some common reasons for modifying a parenting plan include:

  • Changes in the child's needs or preferences
  • Relocation of a parent
  • Changes in the child's school schedule
  • Substantial changes in the parent's work schedule
  • Evidence of a parent's inability to follow the current plan

Significant Change in Circumstances

A significant change in circumstances can warrant a modification. This could include a change in the child's needs due to age, health, or other factors. It could also involve a change in a parent's situation, such as a job relocation or a change in their living circumstances.

To prove a significant change, you'll need to demonstrate that the change was unforeseen at the time of the original parenting plan and that it affects the child's best interests. For example, if a parent has been offered a job in another city, this could be considered a significant change.

Current Plan is Not Working

If the current parenting plan is not working, the court may consider a modification. This could be due to a parent's inability or unwillingness to follow the plan, or because the plan is no longer meeting the child's needs.

For instance, if a parent consistently fails to follow the visitation schedule or if the child is struggling in school due to the current plan, these could be grounds for modification.

It's important to note that the court will always prioritize the child's best interests. Therefore, you'll need to demonstrate how the proposed changes will benefit the child.

Filing a Motion to Modify

To file a motion to modify, you'll need to follow these steps:

  1. Complete the necessary court forms, including the motion and any supporting documents.
  2. File the motion with the court clerk and pay the required fees.
  3. Serve the motion on the other parent or their attorney.
  4. Attend the court hearing, if one is scheduled.

Mediation and Collaborative Law

Before going to court, you may want to consider alternative dispute resolution methods like mediation or collaborative law. These processes allow you and the other parent to work together to reach a mutually agreeable solution.

Mediation involves a neutral third-party facilitator who helps you and the other parent communicate and negotiate. Collaborative law involves both parties and their attorneys working together to reach a settlement.

Modifying a parenting plan can be a complex process, but with the right understanding and approach, it's possible to achieve a solution that's best for your child. If you're considering a modification, it's crucial to consult with a family law attorney to ensure you're following the correct legal procedures and protecting your child's best interests.
