I would suggest you do some documentation now , first off photos of the general conditions of the house. then photos of things that you have made request to be repaired. If your counters were stained when you moved in and you didnt take pics now , if there was say a sink that leaked that they wouldnt fix for a long time then take photos of the damage to the sink base ( underneath ) now. The idea is that if they (she) claim you damaged the property then you will have some kind of record. As to his making a deal with out her what can happen is that a wizzing war could start, she gives proper notice to you about A and he doesnt agree and over turns it so she goes for B and he over turns it ETC ETc Etc , or in order to try to have marital harmony they both come to a agreement and maybe that means non renewal or trying to get you out. So for now I suggest yo act as if they both could be a problem , if a sink needs to be fixed Send them a written on real paper letter via certificate of mailing ( lowest cost way to get a receipt that shows to whom you sent mail , make sure it is addressed to both, keep a copy of the letter requesting the sink repair stapled to your postal reciept and if they refuse to fix it dont make deals with just one, call your city housing inspector and tell them you sent a reppair request to the LL via certificate of mailing and the LL still wont fix the sink so you were wondering they could come out, verify the needed repair and send the LL a repair order letter telling them to fix it. this way no drama , no as the stomach turns. ( Carol Burnett show) dont be surprised if she doesnt want a renewal with you.
