When bringing proof that your spouse has a lover to court in VA... Does it have to be by a PI? What kind of proof does it have to be? We are separated and he has a girlfriend and she spends most of her nights there. HOW many nights would I have to prove that she spends there in order to prove that he does spend the night with her? My lawyer says that since we do not have separation papers signed nether of us are supposed to SLEEP with anyone. He does spend most nights with her. Do I have to pay a professional to prove this or can I have someone I know do it for me?
