Legal Question in Real Estate Law in California

You need to obtain a real estate attorney to help you with this. The actual facts need to be more clearly developed, we need to know the party the deed named as the recipient, and the other circumstances surrounding the transaction. Why did your brother sign a deed? That makes little sense. Why did the notary record them. The duty of a notary is to witness the signature. THere is simply to much unknown to determine the most effective method of proceeding

If your story is true, this was either a mistake that can be corrected by the parties involved, or fraud, which will require a lawsuit. I suggest you speak with an attorney, as it seems there is a lot more to this story than you present here.

There can be a lot more to this than you have had time to explain. Consult a real estate attorney in your area that offers free consultations on such matters.

In my opinion, there could be fraud involved. That is a worst case scenario. If all parties agree there is a mistake then simply correct the mistake.
