In Swinford v. World Aviation Systems, Inc. (Del.Ch., Aug. 29, 2007), read opinion here, the Chancery Court dealt with the attempted enforcement by an ex-employer of an agreement with an ex-employee to arbitrate disputes. The ex-employee refused to admit that the signature on the document was his. Instead, he claimed that his signature was forged. In light of a number of factors, the Court relied on the testimony of a handwriting expert and other circumstances to conclude that the signature on the document actually was the signature of the ex-employee, and therefore, the arbitration provisions of the agreement would control. The facts of this case are unusual, but the decision shows that one can prove that a person signed a document even if the alleged signer denies it.
