New York State requires specific grounds to grant a divorce. These grounds are expressly stated in section 170 of the Domestic Relations Law of New York State and include the following six:
1) cruel and inhuman treatment
2) abandonment
3) confinement in prison
4) adultery
5) living apart pursuant to a decree or judgment of separation for a period of 1 year or more
6) living separate and apart pursuant to a written agreement of separation for a period of 1 or more years
These were the only grounds upon which a divorce in New York State was granted. Judges are generally understanding if both parties are in agreement or there is some egregious conduct on the part of either party.
Now, NY has a No-Fault provision as well.
