Legal Question in Real Estate Law in California

Well, the actions you mention cover part of what is required to obtain title by "adverse possession," it is not clear that you have satisfied all of the requirements, which include "continuous" actual or constructive possession of the property for five years. The interpretation of the possession requirement in court is somewhat technical, and I think your first step would be to confer with a real-estate attorney, bringing him/her all the facts relating to your possession and the presence or absence of the owner of record.
