That old adage

In Horvath v. Bank of New York, N.A., Mr. Horvath claimed that only the original lender could sue on the note secured by the deed of trust on his property. The Fourth Circuit, in an opinion by Judge Wilkinson joined by Judges Keenan and Diaz, was unimpressed:

"Negotiable instruments like mortgage notes that are endorsed in blank may be
freely transferred. And once transferred, the old adage about possession being nine-tenths of the law is, if anything, an understatement. Whoever possesses an instrument endorsed in blank has full power to enforce it."
