7 years ago, my husband and I purchased a home with his parents. It was 50/50. FIL now wants his half, left to the other 3 children, because he got mad 4 years ago, that his golden child (son from 1st marriage) was mistreated by my husband (1/2 brother). My husband has always been a scapegoat for my narcissistic FIL. Sister (1/2 sister, same mother) has been instructed to come after us for FIL contribution, after he dies. He denies this. He loves to attack us verbally, whenever possible. The past 4 years have been hell on earth. He has turned the whole family against us, so we have no support system. The MIL knows nothing about FIL's smear campaign. When we try to tell her about it, she says that it's too hard to believe. She is the ostrich of the family. She just wants everyone to get along. FIL is mean and hateful, when she is not around. He is almost 94 and a diabolical liar. We made a contract years ago and all four of us signed it in front of a notary public. The contract states that if one of us passes away, the three remaining will own the home, and so on, until there is only one. Even though the deed is in our name only, we constructed this contract to make sure that it was fair to all four of us.
The father in law told my husband's half sister to wait and come after the money when he dies, because he doesn't want to be a part of it, even though he started this entire battle. He has destroyed this family. The house was paid, in full, 7 years ago. My husband and I had to take out a mortgage for home upgrades. We are stuck here. Any ideas on ways we can protect ourselves from the SIL?
