What is No-Fault Divorce?

Updated January 24, 2026

A divorce in which the spouse filing does not have to prove that the other spouse did anything wrong, only that the marriage has broken down, using grounds such as irreconcilable differences or an irretrievable breakdown.

Family Law

Understanding No-Fault Divorce

Every state now allows some form of no-fault divorce. The wording of the grounds varies by state, such as "irreconcilable differences," "irretrievable breakdown" or living separate and apart for a set period. Some states allow only no-fault divorce, while others also keep traditional fault grounds such as adultery, cruelty or abandonment. Even in a no-fault divorce, conduct can still matter to some issues in some states, such as alimony, property division when marital money was wasted, or custody when a parent's behavior affects the children.

Examples

  • 1A petition citing irreconcilable differences as the only ground
  • 2A divorce granted after the spouses lived separately for the period required by state law
  • 3A no-fault divorce where one spouse's spending on an affair is still raised during property division

Why This Matters in Legal Cases

Clients often believe that proving the other spouse was at fault will win them a better outcome. In most cases the ground for divorce has little effect on the result, and pursuing fault can add cost and conflict. Knowing when conduct does matter in the client's state, and when it does not, helps set realistic expectations.

Frequently Asked Questions

Can my spouse stop a no-fault divorce by refusing to sign?

Generally, no. In a no-fault divorce, one spouse can obtain a divorce even if the other does not want it. A spouse who does not respond may face a default judgment, although they can still contest issues such as property, support and custody if they participate.

Does adultery matter in a no-fault divorce?

It depends on the state and the issue. In many states, adultery does not affect property division or custody unless it had a financial or child-related impact. Some states allow marital misconduct to be considered for alimony, and spending marital money on an affair may be treated as dissipation.

Do all states have no-fault divorce?

Yes, all states offer some form of no-fault divorce, but the grounds, waiting periods and separation requirements vary by state. Some states also still allow divorces based on fault grounds.
