Adds Section 17702.08 to the Corporations Code. Authorizes a California LLC to present a signed, acknowledged "certification of LLC existence and authority" to a licensed escrow agent, licensed real estate broker, or title insurance / underwritten title company to prove the LLC exists and to identify who is authorized to sign on its behalf. Escrow agents (and the other listed parties) who rely on the certification in good faith are protected from liability, and the resulting transaction is enforceable against the LLC's assets. The certification can be recorded with the county recorder when it relates to real property.
