Long story but dp has left me and children (3 and 5) in family house. House is in both our names although dp pays mortgage. I've said that since dp has left me (I didn't want this) then how and when he sees kids is up to me. He's currently living in a tent. DP and his parents are now talking about getting solicitors involved to give dp access to kids. What rights does he have in this situation? We're not married if that makes any difference. Please help
