A fault divorce is a divorce which is granted after the party asking for the divorce sufficiently proves that the other party did something wrong that justifies ending the marriage. For example, in Texas, grounds for an "at-fault" divorce include cruelty, adultery, a felony conviction, abandonment, living apart, and commitment in a mental institution. The party filing for the divorce must prove that the other party has done something to justify ending the union. Different states have different requirements for obtaining a fault divorce but in each state the spouse filing for the divorce is required to establish a reason for the divorce and provide evidence of the other party’s guilt. The specific grounds for receiving a fault divorce include adultery, impotency, infertility or homosexuality (for heterosexual married couples) of the other party that was not discussed before the union; criminal conviction of a felony or imprisonment of one party for a certain length of time; abandonment or desertion, cruelty, or mental instability of one of the parties.
