Modifying or Ending Alimony in Delaware

In Delaware, alimony can be modified or terminated only upon a showing of real and substantial change of circumstances. Unless the parties agree otherwise in writing, it ends on the death of either party or the remarriage or cohabitation of the recipient.

Real and substantial change of circumstances

Under 13 Del. C. 1519(a), alimony or any other relief awarded may be modified or terminated only upon a showing of real and substantial change of circumstances. Property disposition can be reopened only on circumstances that would justify opening or vacating a judgment under the Superior Court rules, and child support and custody follow their own chapters.

Death and remarriage

Unless otherwise agreed in writing and expressly provided in the decree, the obligation to pay future alimony ends on the death of either party or the remarriage of the person receiving alimony (Section 1519(b)). Section 1512(g) adds cohabitation: unless the parties agree otherwise in writing, alimony ends on the cohabitation of the recipient as well.

Notice duty

A person receiving alimony must promptly notify the other party of remarriage or cohabitation. Failing to do so can lead to disputes about overpayments, so keep records.

Where to file

Alimony orders are enforced exclusively by the Family Court in the county where the respondent resides or is found, or where the petitioner resides if the respondent cannot be found in Delaware, and the Family Court may modify or terminate support obligations formerly decreed by the Superior Court (Section 1519(c)).

Waivers and agreements

A party who waived alimony in writing has no remedy under the alimony statute. Check your decree and any written agreement before assuming a change is possible or automatic.

Child support follows different rules

Child support has its own modification standard: within two and a half years of the last order, a petition must allege with particularity a substantial change of circumstances not caused by the petitioner’s voluntary or wrongful conduct, and an order is not modified unless the formula indicates a change of more than 10%. Beyond two and a half years, neither requirement applies, and a change caused solely by a revision of the formula is not a ground. Alimony has no percentage test: the standard is a real and substantial change of circumstances. See the Delaware child support calculator for the child support side.

Interim alimony ends with the decree

Interim alimony is awarded only while the divorce or annulment is pending. The alimony ordered in the decree is a separate order, so a request to change it is decided under Section 1519, not under the interim order.

What to bring when you ask the court to change an order

Bring the order with its terms, proof of what has changed (income, health, employment, remarriage or cohabitation) and documents showing the change is real and substantial. A clear before-and-after comparison is the most useful evidence.
