Greetings. First, adultery (having sex with someone other than your spouse while married) is a crime in North Carolina. I would also not advise him to sign something that incriminates him.
Now, the grounds for divorce in NC used most often is one year of separation. We do not use adultery as grounds for divorce. Adultery affects alimony, but not the actual divorce. Often in the separation agreement we say the parties had irreconcilable differences and do not elaborate on why they truly separated.
Yes, I would be worried about him removing property from the home, as you will likely never see this property again. You lose the rights to equitable distribution after the date of the divorce, so you must divide all of your property before the date of the divorce. Best of luck.
