1. In the motion for new trial error is assigned upon the 'admission of testimony for the defendant tending to show that he had not executed the note which had been transferred by Griffith to the bank, and also upon an instruction to the jury that if they believed that the defendant had not executed the note, the plaintiff would not be entitled to recover. It is contended that inasmuch as the defendant did not file a plea of non est factum, he should not have been permitted to introduce evidence that the note was a forgery. We do not think this contention is well founded. The note was not the foundation of the plaintiff’s action, within the meaning of the Civil Code (1910), § 5650. It was simply evidence of the plaintiff’s title, and could be attacked by the defendant as a forgery, in the same way that a defendant in an ejectment case can show that a deed offered as evidence of the plaintiff’s title was a forgery. The note was admissible in evidence, and the burden was on the defendant to show that he had not in fact executed it, but he had a right to attempt to carry this burden without having filed a plea of non est factum Anderson v. Cuthbert, 103 Ga. 767 (30 S. E. 244).
2. The trial judge charged the jury as follows'. “The first question is, did the defendant sign the note, or authorize it to be signed for him; then you say further if he was in possession of the property at the time of the filing of the suit. If you find these questions in the affirmative, then you would be authorized to find in favor of the plaintiff.” We think this charge was error, and entitles the plaintiff to a new trial. In the first place there was am admission, in the defendant’s answer, that he was in possession of the mule at the time suit was filed. In the second place, it was not necessa^, in order to entitle the plaintiff to recover, that the defend-' ant should have been in possession of the property at the time of the filing of the suit. It was only essential that the plaintiff should show that it had title to the property in dispute, and that the defendant had been in possession of it at some time after the plaintiff acquired title. The only purpose of a demand in a trover ease is to furnish evidence of a conversion. The defendant having admitted in his answer that he was in possession of a portion of the property, and that he had refused to deliver it to the plaintiff, and having testified that he had traded the mule, no demand was necessary, so far as the mule was concerned; because, taking the defendant’s an*706swer and his testimony together, it is evident, if both are true, ho must have traded the mule after the suit was filed. The trading of the mule was a conversion by the defendant, and no proof of demand was necessary to authorize the plaintiff to recover the mule or its value. So far as the horse is concerned, it does not appear exactly when the defendant delivered the horse back to Griffith. If this was done after the transfer of the note and after its record, of course this was sufficient evidence of a conversion of the horse, as against the plaintiff, and no demand was necessary. If, at the time the defendant surrendered the horse to Griffith, the defendant had no actual or constructive knowledge that the note had been transferred to the bank, he would be relieved, so far as the horse was concerned. The evidence was in sharp conflict as to whether the defendant had executed the note upon which the plaintiff relied in support of its title, and it was harmful error against the plaintiff to instruct the jury that before the plaintiff could recover, it must have appeared from the evidence that the defendant was in possession of the property at the time of the filing of the suit. For this reason the judgment overruling the motion for new trial must be . Reversed.
