Something deposited, laid, or hazarded on the event of a contest or an unsettled question; a bet; a stake; a pledge.

(Law) A contract by which two parties or more agree that a certain sum of money, or other thing, shall be paid or delivered to one of them, on the happening or not happening of an uncertain event. --Bouvier. Note: At common law a wager is considered as a legal contract which the courts must enforce unless it be on a subject contrary to public policy, or immoral, or tending to the detriment of the public, or affecting the interest, feelings, or character of a third person. In many of the United States an action can not be sustained upon any wager or bet. --Chitty. --Bouvier. 3. That on which bets are laid; the subject of a bet. Wager of battel, or Wager of battle (O. Eng. Law), the giving of gage, or pledge, for trying a cause by single combat, formerly allowed in military, criminal, and civil causes. In writs of right, where the trial was by champions, the tenant produced his champion, who, by throwing down his glove as a gage, thus waged, or stipulated, battle with the champion of the demandant, who, by taking up the glove, accepted the challenge. The wager of battel, which has been long in disuse, was abolished in England in 1819, by a statute passed in consequence of a defendant's having waged his battle in a case which arose about that period. See Battel. Wager of law (Law), the giving of gage, or sureties, by a defendant in an action of debt, that at a certain day assigned he would take a law, or oath, in open court, that he did not owe the debt, and at the same time bring with him eleven neighbors (called compurgators), who should avow upon their oaths that they believed in their consciences that he spoke the truth. Wager policy. (Insurance Law) See under Policy.

WAGER OF LAW, Eng. law. When an action of debt is brought against a man upon a simple contract, and the defendant pleads nil debit, and concludes his plea with this formula, "And this he is ready to defend against him the said A B and his suit, as the court of our lord the king here shall consider," &c., he is said to wage his law. He is then required to swear he owes the plaintiff nothing, and bring eleven compurgators who will swear they believe him. This mode of trial, is trial by wager of law. 2. TheWager of law : could only be had in actions of debt on simple contract, and actions of detinue; in consequence of this right of the defendant, now actions on simple contracts are brought in assumpsit, and instead of bridging detinue, trover has been substituted. 3. If ever wager of law had any existence in the United States, it is now completely abolished. 8 Wheat. 642. Vide Steph. on Plead. 124, 250, and notes, xxxix.; Co. Entr. 119; Mod.
