Bouvier's Law Dictionary
1856 Edition

11. When a person uses a name in making a contract under seal, he will not be permitted to say that it is not his name; as, if he sign and seal a bond " A and B," (being his own and his partner's name,) and he had no authority from bis partner to make such a deed, he cannot deny that bis name is A. & B. 1 Raym. 2; 1 Salk. 214. And if a man describes himself in the body of a deed by the name of James and signs it John, he cannot, on being sued by the latter name, plead that his name is James. 3 Taunt. 505; Cro. Eliz. 897, n. a. Vide 3 P. & D. 271; 11 Ad. & L. 594.
