My question involves landlord-tenant law in the State of: Texas
My elderly grandparents (80+ years old) are being forced out by one of my uncles from their home.
Here is a little backstory: Two years ago said uncle's daughter died (17 years old) from an a sudden cardiac event, natural causes, she was living with my grandparents for school purposes. My aunt and uncle live out of State. Because of this, they turned to abusing prescription anti-depressants and who know what else, and they want to sell the house without regard to my grandparents wishes nor financial situation, they basically don't care, and have said as much to all of us. If you're wondering if they need the money, no, they're literally millionaires.
As far as the house, it's in his wife's name (aunt-in-law) but 3 of my uncles paid for the house and my grandparents don't want to leave, they have been there for 16 years. My other aunts and uncles, and grandchildren chip in with my grandparent's needs as best we can, but they're still pretty self-sufficient.
So basically, said uncle has already put the house for sale. What should we do? It's not fair to my grandparents, nor my other family members that paid towards the house.
