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 real, substantial, and unanticipated 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 there's been a substantial change in income, employment status, or the custody arrangement. Vermont courts generally consider a change "substantial" when the recalculated amount differs by at least 10% from the current order. The filing fee for a post-judgment modification is $90.

Spousal maintenance (alimony). Rehabilitative maintenance can be modified if the receiving spouse's circumstances change — they become employed, their health improves, or they complete the education the maintenance was designed to support. The paying spouse can request a reduction if their income drops significantly.

Critical exception: If the original divorce decree explicitly states that spousal maintenance is non-modifiable, or if the parties waived the right to future maintenance in their stipulation, the court cannot change it. This is a permanent decision made at the time of divorce.

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 only exception: if one party can prove that the other committed actual fraud during the property division — for example, deliberately hiding assets or lying on financial affidavits. This is an extremely high bar that requires filing 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 in the county where the original divorce was entered. 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

There's no mandatory waiting period before you can file for modification — you can file as soon as the decree becomes absolute. However, 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, either party can request a review from the Office of Child Support (OCS) every three years without demonstrating changed circumstances. The OCS will recalculate support based on current incomes and the existing custody arrangement.

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.
