has anybody ?

so me and my boyfriend looking for an apartment and we can’t get approved for anything bc he got stuck on a lease and owe money after the apartment complex told him he was off of it.. i have no income as im pregnant and have complications this time so it’s just him.. and my grandma said she’ll put the apartment in her name (it’s actually a duplex) anyways, does anybody know anybody that has done this before or have you did it before? my grandma is scared she’ll get in trouble for it but i dont see how if they will be getting there money every month for rent & we won’t cause any issues as we have nowhere else to go and we will have 2 kids.. it’s not a section 8 housing or anything like that.
