Legal Question in Real Estate Law in California

I believe most lawyers would prefer to restrict the term "against the law" to matters that involve violation of a statute or are a common-law crime, which this probably isn't. It's more of a careless misrepresentation that might theoretically allow you to recover money damages in a civil suit, but the economics don't favor your coming out ahead. You might be able to get the property owner's name by direct inquiry with the management firm, or more likely perhaps from property records at the county assessor or recorder's office.
