Greetings. Yes, you may be able to get the IM conversation admitted in court. I would always suggest that someone hire a PI to find out of their spouse was cheating if they may have an alimony or equitable distribution claim.
Adultery is a bar for a dependent spouse trying to receive alimony. Hope that helps.
