How to Modify Custody in Maine

A custody order isn't permanent. When circumstances change significantly — a new job, a relocation, a child's evolving needs — Maine law provides a process to modify parental rights, primary residence, and child support. But you can't just ask for a change because you're unhappy with the current arrangement.

The Legal Standard: Substantial Change in Circumstances

To modify a custody order in Maine, you must demonstrate a substantial change in circumstances that has occurred since the last order was entered. The court then re-evaluates the arrangement under the best-interest-of-the-child standard.

Changes that courts typically recognize include:

• A parent's relocation that disrupts the existing schedule
• Documented safety concerns (substance abuse, domestic violence, neglect)
• A significant change in either parent's work schedule that makes the current plan unworkable
• The child's developmental needs shifting as they age (a schedule that worked for a toddler may not suit a teenager)
• A parent's repeated failure to follow the existing order

Changes that usually don't qualify: general dissatisfaction with the arrangement, a new romantic partner, or the child preferring one household over the other without a substantive underlying reason.

How to File: Motion to Modify (FM-062)

The process starts with filing a Motion to Modify (Form FM-062) with the District Court that issued the original order. You'll need to:

1. Describe the specific change in circumstances
2. Explain why the current order no longer serves the child's best interests
3. Propose a modified arrangement
4. Serve the other parent with a copy of the motion

The court will schedule a hearing. If the modification is contested, the case goes through the same process as an initial custody dispute — Case Management Conference, possible mediation, and trial if no agreement is reached.

Child Support Modifications Have a Different Rule

Child support follows a separate modification standard. Under Maine law, either parent can request a review every three years without demonstrating a substantial change in circumstances. The court recalculates using current income figures and the state's child support guidelines.

Between those three-year windows, you can still file for modification if there's a substantial change: job loss, significant income increase or decrease, a change in the child's healthcare needs, or a shift in the parenting schedule that affects the "substantially equal care" determination.

To reduce child support, you'll need to show a legitimate reason for reduced income. Voluntarily quitting a job or reducing hours to lower your obligation is likely to result in the court imputing income at your previous earning level.

Timeline and Cost

Modification filings typically cost the same as initial filings ($120 filing fee, unless waived). The timeline depends on whether the modification is contested. An agreed-upon modification can be approved in weeks; a contested one may take several months to work through mediation and a hearing.
