Fathers house
My father is divorced and in his papers it states that we owns half of the house he lives in and my mother owns the other half. My husband and I moved in with my father 2 years ago to help take care of him because he is sick. He told us that we are to get his half of the house. He typed up a letter stating this. It says “I ____ do on this date of February 02, 2007 leave all my worldly goods and possessions to ___ and ___ This letter is signed and notarized. I just want to make sure this is a good legal document and will hold up on court if need be. I also have a signed and notarized general power of attorney.

Contesting will
My Aunt, who lives in Tn but whose will is registered in Fl has left 3 nephews out of her will. She has included 5 neices and 1 nephew who is a co-executor along with one of the neices. The aunt is senile. Is there a way for the 3 nephews to contest the will for inclusion as beneficiaries with equal standing. Secondly, is there a way to determine from the will why the 3 were left outl. The one executor nephew refuses to acknowledge that a will exists or where it is located. He does have a general power of attorney to handle the Aunt’s affairs. The Aunt is still living. My sister, one of the neicies, told me in front of her husband that she would divide her share equally with me if I am not included in the will. Is this enforceable?
