Grounds for Divorce

No Fault:
1- Irreconcilable Differences: New Jersey is a “no fault” divorce State. This means that one party may file for divorce under the grounds of irreconcilable differences without the necessity of showing any fault on behalf of the other party, provided that those irreconcilable differences existed for at least 6 months prior to filing for divorce.
2- Separation

3- Adultery
4- Extreme cruelty
5- Desertion
6- Addiction (Habitual drunkenness or drug addiction)
7- Imprisonment
8- Institutionalism
9- Deviant sexual behavior

Residency requirement:

Generally, in order to file for a divorce in New Jersey, one party must be a resident of the State New Jersey for at least one year prior to the filing of the action. The exception to this rule is in the case of adultery. There is no one year residency requirement if a party files for divorce under the grounds of adultery. The only requirement is that one party was a resident of New Jersey at the time when the cause of action arose, and continued to be a resident until the filing of the action.
