Match each marital status event with its legal effect on spousal competency to testify for the prosecution: Events: 1. Decree of divorce or nullity 2. Judicial separation 3. Marriage void ab initio Effects: - Spouses become competent for the prosecution only regarding matters occurring after the decree - Does not remove the rule of spousal incompetency - Incompetency rule does not apply because legally no marriage existed

The notes distinguish among termination by divorce or nullity, judicial separation, and a marriage void from the outset. They also state that a spouse remains incompetent concerning matters arising during the marriage despite a later decree of divorce or nullity. **Key takeaway:** The legal status and timing of the events both matter. **Glossary:** Nullity: a decree treating a marriage as invalid; ab initio: from the beginning.
