interposing this judgment as a counterclaim. Sections 4914, 4915, Comp. Laws. The intervener can maintain his claim to priority, as against this judgment, in one way only. He must show that to the extent of his lien for services he is, in equity, the owner of plaintiff's cause of action on the undertaking. If he became such owner before Sullivan’s right to set-off the judgment accrued to him, and Sullivan had notice of his rights at the time he (Sullivan) bought the judgment against plaintiff which he seeks to set off, then we are of opinion that, to the extent of the intervener’s lien, the judgment docs not constitute a proper counterclaim.
What were the rights of the intervener with respect to this undertaking, and the cause of action thereon against Sullivan? We are clear that he had all the rights with regard to this instrument that he had with respect to the judgment against Mead in favor of the plaintiff. This undertaking was executed by Sullivan in the very case in which the judgment was rendered, and in the undertaking Sullivan promised to pay any judgment which the District Court might render in the case. The undertaking is but an additional security, provided for by the law, for the payment of the money due from Mead to the plaintiff. The lien which attaches to the money must necessarily attach to the undertaking. The money which Sullivan is to pay under this undertaking is the money which the attorney has secured for his client by the labor he has bestowed upon the original case. Nor is authority wanting to support our views. Newdert v. Cunning: ham, 50 Me. 231; Hobson v. Watson. 34 Me. 20; Martin v. Hawks, 15 Johns. 405; Wilkins v. Batterman, 4 Barb. 48. The reasoning upon which these cases rest is that the rights of an attorney, under his lien, are those of an equitable assignee of the judgment, to the extent of his lien. Under our statute he would be the equitable assignee of the money due from the debtor to the creditor. Of course, as such assignee, he would have the same interest in any undertaking or cause of action which the creditor, his client, might have, as security for the payment of such money. The
