Where an acceptance by the debtor is material, such acceptance can be made only by such words or conduct on his part as to show his willingness to accept.1 If the debtor has paid a check upon a forged endorsement, such payment is not such an acceptance of the check that the payee may maintain action thereon as against the bank on which it is drawn.2 Any words or conduct on the part of the debtor, which disclose to the assignee the intention of the debtor to accept the assignment, are sufficient.3 The fact that the debtor has marked an assignment "accepted,"4 or that he has taken the notice of assignment without objection and filed it,5 has been held to amount to a sufficient acceptance of the assignment.

Under some statutes, however, a written acceptance is necessary.6
