My father passed away in early April. He left behind a wife with whom he was separated for 20 years, myself and my half brother. His estranged wife naturally has come around. She took all legal documentaion from the house and is not willing to give us copies. She is on the title to one of his properties and the other is held in trust and is a sole and separate property. The will he left behind is one he made himself on the computer and is only witnessed by my half brother and his estranged wife and they are both beneficiaries, there are no other witnesses except for the notary who notarized it. His houses are both worth over 500,000. Any help would be great. By the way we are in California.
