What are the process of adding names to a title in California? - Property is located in Alameda County, CA.
1) Anay idea about the expences? ( will is be few hundred dollars or may be more? )
2) how long it takes ( 2-3 weeks or few months ?)

Near the top of the Real Estate Law forum is a sticky post that explains how to add names to a deed. The expenses depend on the recording fees in your area and if you have it handled by an attorney or title company. It shouldn't be more than a few hundred dollars. If there are no "issues" then it can be done in a day.
