What is the name of your state (only U.S. law)? California My mothers boyfriend was allowed to continue living in my mom's house after she passed away a year ago. His son does not live there. My mothers boyfriend was in the hospital for two and a half months in and out of ICU, he passed away just a few days ago and his son has been using the garage of my mother's home as a free place of business. The son went to the father while in the hospital with 2 family members and a letter giving him permission to keep the garage to use it as he pleases as long as he pleases and had the father sign the letter and it was witnessed by the two family members signatures, none of them are of any legal authorities. Is this considered a legal binding contract to a place that is not owned by the father?*in Los Angeles, CA
