Legal Question in Real Estate Law in California

Re: Parents Selling Property

Unfortunately, you have little chance of claiming an entitlement to property simply because you have resided there for 20 years and/or cared for grandparents. First, if grandparents had wanted you to have an interest, they could have put you on title along with Mom or instead of Mom, but they did not. Also, if you did not have to pay rent all those years, you were benefitting and a court could determine that your free rent all those years was in return for your care of grand parents. There is no basis for a claim of adverse possession, because you were not possessing "adversely" and you likely did not pay the property taxes, a requirement.

Re: Parents Selling Property

Sounds like your grandparents made their decision when they put their property in your mother's name. While you did not specify whether you were paying rent or not, it appear you may have enjoyed the property for twenty years without charge. However, in response to your question, unles there exists a formal document stating otherwise, it appears you have little or no chance of changing things unless you can convince your mother to make changes.
