I've been living in this house for 46 years with my mother, sister and brother. My beloved uncle decided to take over the house because the house needed repairs. He was approved for a second mortgage. Unforunatelly he passed away. My aunt became exceutive of his estate or so she claimed, Any she sends a eviction notice to her own family, My mother was the caretaker of my grandparents after my grandparents died my mother took over the repairs and paid the taxes on the house. What should we do?

You can check at the court house as to who actually owns the house
(on the deeds) how did your uncle decide to "take over the house" and who did he take it over from.
Who had the first mortgage,

Was there a will,

After the granparents died, who got ownership of the house ?
