Legal Question in Real Estate Law in California

Care of, as in send to this person care of someone else.

"c/o" on a deed or in any writing is an abbreviation for "in care of" and is used (for example) to direct delivery to A at B's address. As such, it has little or nothing to do with conveying rights.
