A potential renter's father living outside WA state agreed to be co-signer. His credit check is fine. He won't be in Seattle to physically to sign the rental agreement. What procedures do we need to follow to have the right signatures on the right forms? Must we sign the same hard copy he does? Or can he sign a copy, fax it in, we sign the faxed copy and have him mail the actual hard copy and then resign it again at a later date after it arrives? Must the copy be notarized as well? Thank you in advance for your answer.
