Legal Question in Family Law in New York

In the U.S. polygamy is illegal. If a man marries two people he could be convicted of a crime, but it is not a crime that is aggressively prosecuted in most jurisdictions. You should know that according to the laws of all states, if someone is married and they marry a second person without divorcing the first, the second marriage is void. More importantly, if you're separated from this person, perhaps it's time you think about divorcing him?
