It is not the amount of days that will be relevant, but whether your ex can prove that your current boyfriend pays for bills or food in your household. Also, as long as your boyfriend has his own home, and gets his mail at his own home, cohabitation will be almost impossible to prove.

Please be advised my answers to questions does not constitute legal advise and you should not rely on it, due to the fact that we have never met, I have not been aprised of the facts in you case nor have I reviewed any documents.


Cohabitation is a much an economic analysis as it is an overnight stay analysis. The frequency of the overnight stays is not determinative.

It is fact sensitive so no amount of overnights trigger a reduction. An attorney can explain your potential exposure to you in detail.

The crux of your ex attempting to prove cohabitation to reduce or terminate his support for you is whether or not you derive an economic benefit from the presence of your current boyfriend in your home. If you are not sharing bank accounts or helping each other pay bills on your home, your ex is probably barking up the wrong tree. That said, there may be facts regarding this matter to which I am not privy and as such my answer could change depending on new information.


The other attorneys who responded to your question are correct in that "cohabitation" in connection with alimony modification cases is as much a financial analysis as one of whether your boyfriend stays at your home (or you at his) several nights per week. I recommend consulting with an experienced Family Law attorney who can discuss the specific facts and circumstances involved in your matter with you more in-depth and can guide you accordingly.
