Yes, the former Husband needs to file in Family Court or the original Divorce Court for a cessation of Maintenance/Alimony/spousal support. It is up to the Husband to prove that she was cohabiting with another man so that it is tantamount to being married to another man. If he can prove that as a fact, then he can stop his payments once a court issues an Order to that effect.
