In a Florida post-judgment divorce proceeding, alimony may modified assuming the parties did not agree to make it non-modifiable in writing. The general rule in a Florida post-judgment divorce proceeding is, when the former spouse who is receiving alimony remarries, then his/ her right to receive alimony may be terminated. Likewise, in Florida, when the former spouse who is receiving alimony starts living with someone in a “supportive relationship” (as if married), then his/ her right to receive alimony may be decreased or terminated altogether. The burden would be on you to prove that your Ex is in a supportive relationship, for example, has your Ex made major purchases with the other person? Do they have joint bank accounts and/ or lines of credit? These are just a few of the types of questions to be asked.
