¶1This suit is brought to recover damages for the non-delivery of certain property in Missouri, given in exchange for city lots, and also to recover hack the difference in price, $491 12, between the property received and that given in exchange. This difference in price, was equalized in the act of exchange by the transfer by the defendant to the plaintiff, of a claim to that amount, against one George Leach.
¶2On the trial, the defendant excluded all testimony on the ground, that the petition contained no sufficient allegation of the putting in mora. Plaintiff excepted, and prosecutes this appeal from the judgment of nonsuit against him. The only question, therefore, is whether the proof ought to have been received under the petition ?
¶3The allegation in regard to Leach’s claim is, “ that said Glover (the defendant) has deceived your petitioner, and that the claim which he transferred to petioner against George Leach, never had existence, and was not due by Leach, and is not now due, and that, moreover, said Leach is insolvent and has no means to pay ; that said Glover is bound unto petitioner for the amount of said claim.”
¶4After alleging that one George Leach is in possession of the property received in exchage under an unexpired lease, or some other contract, and that he refuses to deliver possession, notwithstanding every possible diligence to obtain it, petitioner alleges, that “ he has informed said Glover- of the facts, and said Glover refuses to do any act by which petitioner can get possession; that said Glover well knew of the existence of said contract between him and Leach, and did not give petitioner any knowledge, but fraudulently concealed the same from your petitioner, to his great injury and damage.”
¶5Petitioner, after showing the expenses which his attempt to obtain possession had occasioned him, to the amount of over $400, alleges further : “ That he has suffered damage by beiDg deprived of the possession of said lands, and the fraudulent acts of said Glover, in keeping secret the contract between Mm and Leach, and his neglect and refusal to put petitioner in possession thereof.”
¶6The allegations appear to us to be sufficient to authorize the introduction of the proof offered by the plaintiff. If the pretended claim against Leach had no existence, the defendant was bound for the $491 12, under his obligation of warranty' — for he who sells a debt or incorporeal right, warrants its existence at the time of the transfer, though no warranty be mentioned in the deed. C. C. 2616.
¶7The law also imposes upon the vendor the obligation of delivering the thing sold. O. 0. 2450, 2631.
¶8If he refuse to comply with his obligation, lie thereby waives a formal putting in mora by such refusal. The party is not required to demand performance of *248him who has already expressly refused to perform his obligation — for lex nominan cogit ad vana. 3 Rob. 358 ; 18 La. 513.
¶9It is, therefore, ordered, adjudged and decreed by the court, that the judgment of the lower court be avoided and reversed, and that this case be remanded to the lower court for a new trial, with instructions to permit the plaintiff to introduce proof to sustain the allegations of his petition ; the defendant paying the costs of the appeal.
