In Pennsylvania, divorce is divided into two categories: “fault” and “no fault.” A divorce on fault grounds requires that the plaintiff prove that he or she is the innocent and injured spouse and that the other spouse is guilty of one of six categories of marital misconduct: adultery, desertion, cruel and barbarous treatment, bigamy, imprisonment for a crime, and indignities.

A divorce based on no-fault grounds must assert that the marriage is irretrievably broken.
