D.C. Code § 28:3-401
This section is not intended to affect any other law requiring a signature by mark to be witnessed, or any signature to be otherwise authenticated, or requiring any form of proof.
2. A signature may be handwritten, typed, printed or made in any other manner. It need not be subscribed, and may appear in the body of the instrument, as in the case of “I, John Doe, promise to pay * * *” without any other signature. It may be made by mark, or even by thumb-print. It may be made in any name, including any trade name or assumed name, however false and fictitious, which is adopted for the purpose. Parol evidence is admissible to identify the signer, and when the signer is identified the signature is effective. Indorsement in a name other than that of the indorser is governed by Section 3-204(d).
1. Obligation on an instrument depends on a signature that is binding on the obligor. The signature may be made by the obligor personally or by an agent authorized to act for the obligor. Signature by agents is covered by Section 3-402. It is not necessary that the name of the obligor appear on the instrument, so long as there is a signature that binds the obligor. Signature includes an indorsement.
