whose signature has been forged, does not render hím liable thereon, there being no new consideration; 67 Pa. 391; s. c. 5 Am. Rep. 445, n.: 83 Ohio St. 405; s. c. 31 Am. Rep. 546, n. But if a contract be merely against conscience, then if a party, being fully informed of all the circumstances of it and objections to it, voluntarily confirms it, his ratification will stand; 67 Pa. 217; 62 III. 483; s. c. 14 Am. Rep. 106. When a claim is founded upon an act done without the claimant's knowledge and authority, by a person claiming to act as his agent, the bringing of an action by him based upon that act is a ratification of it; 155 U.S. 13. A forged note cannot be ratified; L. R. 6 Ex. 49; 92 Pa. 447; but see 4 Allen 447. A party from whom a contract has been wrung by duress must disclaim it on the recovery of freedom, subsequent recog- nition is the equivalent of ratification; 23 Misc. Rep. 178. Ratification will, in general, relieve the agent from all responsibility on the con- tract, when he would otherwise have been liable; 2 Br. & B. 452. See 16 Mass. 461; 8 Wend. 494. See ASSENT; Ayliffe, Pand. *386; 18 Viner, Abr. 156; Story, Ag. 239. See, generally, 25 Am. Law Rev. 14; AGENCY. A principal having the right to disaf- firm acts of an agent must do it promptly, and if not done within a reasonable time ratification will be presumed; 120 U. S. 256. The principle of ratification by laches or delay is applicable to a muni- cipal corporation, such as a county; 139 U. S. 684. An infant is not, in general, liable on his contracts; but if, after coming of age, he ratify the contract by an actual or ex- press declaration, he will be bound to per- form it, as if it had been made after he attained full age. The ratification must be voluntary, deliberate, and intelligent, and the party must know that without it he would not be bound; 3 Pa. 428; see 12 Conn. 551; 10 Mass. 137; 4 Wend. 403; and now in England must be in writing. But a confirmation or ratification of a contract may be implied from acts of the infant after he becomes of age, as, by enjoying or claiming a benefit under a contract he might have wholly rescinded; 1 Pick. 221; and an infant partner will be liable for the contracts of the firm, or at least such as were known to him, if he, after becoming of age, confirm the con- tract of partnership by transacting busi- ness of the firm, receiving profits, and the like; 2 Hill S. C. 479; 1 J. B. Moore 289; 33 S. C. 285. Where an infant, during his minority, has made a deed or mortgage, his mere failure to disaffirm the conveyance on com- ing of age, without some positive and clear act of affirmation, will not amount to a ratification; 86 Ala. 442; 86 Ky. 572.
