Vermont Divorce Modification After Decree: How to Change Custody, Support, or Alimony

Life changes after divorce. A new job, a relocation, a change in the children's needs — any of these can make the original decree unworkable. Vermont law allows post-decree modifications, but only for certain parts of the divorce order, and only when you can demonstrate a real change in circumstances.

What Can Be Modified

Child custody (Parental Rights and Responsibilities). Either parent can request a modification to legal responsibility, physical responsibility, or the parenting schedule. You must show a change in circumstances since the original order and that the proposed change serves the child's best interests under 15 V.S.A. § 665.

Common triggers: a parent's relocation, a change in the child's school needs, a parent's substance abuse or mental health issue, the child aging into adolescence and needing a different schedule.

Child support. Either parent can request a recalculation when a material change in income, employment status, or the custody arrangement affects the guideline amount. The filing fee for a post-judgment modification is $90.

Spousal maintenance (alimony). An existing maintenance award may be modifiable depending on the decree and the parties' circumstances. If the parties waived maintenance or the decree did not award or reserve it, it cannot be requested later.

Critical exception: If the parties waived spousal maintenance, or the decree did not award it or reserve a future request, it cannot be requested later. If the decree labels an existing award non-modifiable, obtain advice before seeking a change.

What Cannot Be Modified

Property division is permanent. Once the divorce decree becomes absolute (after the 90-day nisi period), the property settlement cannot be changed. The court divided your assets and debts based on the circumstances at the time of the divorce, and that division is final.

The recognized exceptions are actual fraud or highly unusual circumstances. For example, deliberately hiding assets or lying on financial affidavits may support a fraud claim. This is an extremely high bar that may require a separate legal action.

This is why getting the property division right the first time matters more than any other part of the divorce. Child support and custody can be adjusted later. Property division cannot.

How to File for Modification

1. File a motion. Submit a post-judgment motion to the Family Division under the court's current filing instructions. The filing fee is $90.

2. Demonstrate changed circumstances. Your motion must specifically describe what has changed since the original order. Vague claims like "things are different" won't survive. Include dates, documentation, and specific facts.

3. Serve the other party. Your ex-spouse must be formally served with the motion and given the opportunity to respond.

4. Attend a hearing. The court will schedule a hearing where both parties present their positions. Bring updated financial affidavits, pay stubs, and any evidence supporting the changed circumstances.

Timing Considerations

Before filing, confirm that the decree is absolute and check the Family Division's current post-judgment filing instructions. The court expects a genuine change in circumstances, not buyer's remorse about the original agreement.

Filing a modification within months of the decree, without a clear triggering event, signals to the judge that you're trying to relitigate the divorce rather than responding to a real change. Courts are skeptical of these early filings.

For child support specifically, check with the Office of Child Support about whether a review or recalculation is available without demonstrating changed circumstances and what timing rules apply.

Protecting Yourself in the Original Decree

The best time to plan for post-decree modifications is during the divorce itself. A few decisions made at the stipulation stage can save significant trouble later:

• Reserve the right to request spousal maintenance. If you waive it in the stipulation, you can never request it — even if your circumstances change dramatically.
• Include a cost-of-living adjustment clause. For child support, agreeing to automatic annual adjustments based on the Consumer Price Index can reduce the need for formal modification filings.
• Be specific about relocation provisions. Address what happens if either parent wants to move out of state — vague language creates expensive disputes.

The Vermont Divorce Filing Process Guide includes a nisi decision worksheet that helps you think through these long-term implications before you sign the final stipulation.
