alimony termination

Alimony Termination

Do you suspect your former spouse is living with someone else while you are paying maintenance? Alimony termination is possible in the event of cohabitation and requires presenting convincing evidence. Under Illinois, Indiana, Wisconsin, and Michigan law, an order for maintenance may be modified or terminated only upon a showing of a substantial change in circumstances. The lack of an intimate or sexual relationship does not prohibit a finding of cohabitation!
