I am leasing a small house in Richardson, TX from an individual. Since we signed the lease 22 months ago, one of the people on the lease has died (Landlord) his wife is the survivor. My problem is the Son is not very respectful of my time, will call and make an appointment then never show. Then the next day call less than 1 hour to show the place. I have asked him to give me atleast 24 hours. Can I refuse to let him in to my home since he is not on the signed lease. And the wife that is on the lease is still alive.
