A dissolution of marriage is the formal legal process for ending a marriage through the courts, essentially what most people call a divorce.

What is a dissolution of marriage?

In plain terms, a dissolution of marriage is when a court legally ends a marriage and issues an order (or “decree”) that says the spouses are no longer married. This process doesn't just end the relationship; it also resolves key issues like property division, debts, child custody, child support, and sometimes alimony.

Some states use the word “dissolution” instead of “divorce,” especially where no‑fault divorce is the norm (you don’t have to prove cheating, abuse, etc. — it’s enough to say the marriage is irretrievably broken or there are irreconcilable differences).

Key features at a glance

  • It is the legal ending of a valid marriage by a court.
  • It fully terminates the spouses’ legal status as a married couple.
  • It usually covers:
    • Division of marital property and debts.
* Child custody/parental responsibility and parenting time.

* Child support and spousal support (alimony), if applicable.
  • It can be:
    • Uncontested – spouses agree on all terms, the court mainly approves the agreement.
* **Contested** – spouses disagree and a judge decides some or all issues.

How the process typically works

Details vary by state, but the broad steps are similar.

  1. One spouse files a petition (or complaint) for dissolution with the court, stating the grounds (often “irretrievable breakdown” or “irreconcilable differences”).
  1. The other spouse is formally “served” and has a chance to respond.
  1. Both sides disclose finances (income, assets, debts) so property and support can be fairly handled.
  1. The couple negotiates, mediates, or litigates:
    • Settlement talks or mediation are common, and many cases end in agreement rather than trial.
  1. The judge reviews any agreement or decides disputed issues, then signs a final judgment/decree of dissolution.
  1. The marriage is officially over on the date the judge signs that final order; a certificate of dissolution can be issued as proof.

Term What it does Key idea
Dissolution of marriage Legally ends a valid marriage and resolves finances, custody, and support. Modern/no‑fault style end to marriage; often same thing people mean by “divorce.”
Divorce Also ends a valid marriage with court orders on property, kids, support. In many places it is just another word for dissolution.
Annulment Declares the marriage legally void, as if it never existed. Used in limited situations (fraud, bigamy, incapacity, etc.). Unlike dissolution, it “undoes” rather than ends a valid marriage.

Quick story-style example

Imagine two spouses who have grown apart over the last few years. They agree the marriage is over, don’t want to blame each other, and just want a clean, respectful separation. One spouse files a petition for dissolution saying the marriage is irretrievably broken, they exchange financial information, work out an agreement on the house, debts, and a parenting plan, then submit it to the judge. Once the judge signs the final dissolution decree, they are no longer married and can move forward with separate legal and financial lives.

Important note

Laws and terminology differ by state and country, including grounds, residency requirements, waiting periods, and procedures. For personal advice about your situation, it’s wise to speak with a qualified family law attorney in your area.

TL;DR: A dissolution of marriage is the court process that legally ends a marriage, divides property and debts, and sets orders about children and support—essentially, it’s what most people think of as a divorce.
