Judgment Nisi

The initial, temporary judgment of divorce. When courts grant divorces, their judgments are not final until the expiration of a statutory "waiting period" known as the nisi period. It begins when the judgment nisi enters and ends upon entry of the "judgment absolute" on the docket.

The initial judgment of divorce. When courts grant divorces, their judgments are not final until the expiration of a statutory "waiting period" known as the interlocutory or nisi period. It begins when the interlocutory judgment enters and ends upon the "final judgment," "judgment absolute," or "final decree." State law varies greatly in this regard, so check with counsel.
Despite your judgment of divorce nisi or interlocutory decree, you are still legally married and cannot remarry until the judgment becomes "final" or "absolute." Also, during the interlocutory or nisi period, your spouse has the right to inherit from you unless a separation agreement waiving such rights was executed. Check with counsel if you are feeling mortal.
Our misguided legislatures, in an effort to save obviously failed marriages, require this waiting or "warming-up" period in the highly unlikely event the parties reconcile. We have heard of "cooling off" periods before gun purchases, but our lawmakers are unrealistic if they think a warming-up period can save marriages after an interlocutory judgment. Besides, it would be easier for parties to remarry than stop the clock on an interlocutory judgment.
