Fault-Based Divorce
A fault-based divorce is one where the filing spouse claims specific misconduct by the other spouse — like adultery, abandonment, or cruelty — as the legal grounds for ending the marriage.
What It Means in Plain English
While most divorces today are filed on no-fault grounds, some states still allow — and some situations call for — a fault-based divorce. In a fault-based divorce, you allege that your spouse's specific behavior was the reason the marriage failed. Common fault grounds include adultery, physical or mental cruelty, abandonment, imprisonment, and substance abuse.
Proving fault requires evidence — and often a court hearing where both sides present their cases. This makes fault-based divorces more complex, more expensive, and more emotionally charged than no-fault divorces. The other spouse gets to respond and contest the allegations.
In states where fault is recognized, proving it can sometimes affect financial outcomes. A judge may award a larger share of marital property or higher alimony to the 'innocent' spouse in some circumstances. However, the impact of fault varies widely by state — in many states, fault has little or no effect on property division.
Why It Matters for Your Case
Understanding fault-based divorce helps you decide whether to pursue it or simply file no-fault. Unless fault is likely to significantly improve your financial outcome — and your state allows it to influence property or support decisions — the added time, cost, and emotional burden of proving fault often isn't worth it.
Even if your spouse genuinely did wrong, a no-fault divorce may serve your interests better. Courts are generally focused on fairness going forward, not punishment for past behavior. Your attorney can help you evaluate whether pursuing fault grounds makes strategic sense in your specific situation and state.
Real-World Example
For example, Susan discovers her husband has been unfaithful throughout their marriage. She files for divorce on fault grounds of adultery in a state where adultery can influence alimony awards. At the divorce hearing, she presents evidence of the affair. The judge considers this conduct and awards Susan a higher alimony payment than would have been typical in a no-fault case.
