MR. JUSTICE HOLLOWAY
delivered tbe opinion of tbe court.
The complaint in this action alleges that on June 21, 1910, one Ira Miller, being then indebted to tbe plaintiff, executed and delivered to it tbe following order in writing:
“June21st, 1910. No. 0909. $400.00
“To J. P. Bain, Knerville, Mont.
“Please pay to tbe order of Tbe A. H. Averill Machinery Co. (a corporation), of Portland, Oregon, Four Hundred no-100 Dollars, and charge the same to my account for plowing done. This order is given The A. H. Averill Machinery Co. as collateral security to notes held by it, the net amount, if collected, to be credited on said notes; otherwise this order to be returned to drawer. Ira Miller. ’ ’
And that plaintiff thereupon presented the order to defendant Bain, who indorsed it in writing as follows:
“I hereby accept this order, payable Nov. the 1st, 1910, at First State Bank, Stanford, Mont. And I agree to pay interest at the rate of ten per cent per annum after maturity, if not then paid. J. P. Bain.”
It is then alleged that the defendant has not paid the sum of $400 or any part thereof, and a prayer for judgment follows. *514The defendant prevailed in the lower court, and plaintiff has appealed from the judgment and from an order denying its motion for a new trial. At the opening of plaintiff’s case, the ■defendant objected to the introduction of any evidence on the ground that the complaint does not state facts sufficient to constitute a cause of action. The objection was overruled, but if it should have been sustained, it is unnecessary to consider what other errors were committed upon the trial. If the complaint does not state a cause of action, it would not sustain any judgment which plaintiff might secure.
The complaint discloses upon its face that the order was not delivered by Miller, or accepted by plaintiff, with the intention that the general title to it should pass. It was only intended as collateral security to Miller’s indebtedness, and so recites.
When used in connection with the term “security,” the word “collateral” has no technical,.legal significance distinct from its common, well-understood meaning. (Seanor v. McLaughlin, [1] 165 Pa. St. 150, 32 L. R. A. 467, 30 Atl. 717.) “The term ‘collateral security’ or ‘collateral’ means a pledge of incorporeal property assigned or transferred and delivered by a debtor or some one for him to a creditor as security for the payment of a debt or the fulfillment of an obligation. It stands by the side of the principal obligation as an additional means to secure the payment of the debt or fulfillment of the obligation.” (Jones on Collateral Securities, 3d ed., sec. 1; Moffatt v. Corning, 14 Colo. 104, 24 Pac. 7; Colebrooke on Collateral Securities, 2d ed., sec. 2; International Trust Co. v. Union Cattle Co., 3 Wyo. 803, 19 L. R. A. 640, 31 Pac. 408; 2 Words & Phrases, 1252.) The term refers to personal property exclusively and in common parlance to choses in action. (31 Cyc. 786.) The transaction by which collateral security is delivered by the debtor and accepted by the creditor constitutes a pledge. (Secs. 5774, 5775, Rev. Codes; Jones on Collateral Securities, [2] sec. 1.) The legal title to property pledged remains in the pledgor. (Leggat v. Palmer, 39 Mont. 302, 102 Pac. 327.) The pledgee has a special property interest in the thing pledged; *515that is, be bas a lien upon it which depends for its validity upon possession. (Rairden v. Hedrick, 46 Mont. 510, 129 Pac. 498.) When the principal debt is paid, the pledge is discharged (31 Cyc. 851), and the pledgor is entitled to a return of the pledge. (Seanor v. McLaughlin, above.)
These elementary rules of law suffice to illustrate the relationship of the parties to this action. Since it was not the intention of Miller or plaintiff that the absolute title to the Bain order should pass, it could not have been the intention of Bain, in accepting the order, to bind himself unconditionally to pay the amount to plaintiff; and plaintiff could not have understood [3] that such unqualified liability existed. The order and acceptance, executed contemporaneously and relating to the same transaction, are to be construed together. (Lyon v. Dailey Copper Min. & S. Co., 46 Mont. 108, 126 Pac. 931.) In order to [4] state a cause of action upon a contract, the plaintiff must disclose the existence of a valid agreement, a right in himself, and a breach by the defendant. Without the existence of the principal debt, plaintiff could not enforce payment of the collateral security; and in failing to allege that the whole or some part of Miller’s indebtedness remained unpaid at the time this action was commenced, plaintiff failed to state facts sufficient to disclose any right to enforce collection of the Bain order, which was given merely as further security for the payment of such indebtedness. (16 Ency. Pl. & Pr. 638.) The allegation [5] that Miller was indebted to plaintiff in June, 1910, is not sufficient to disclose an indebtedness in November, 1911, when this action was commenced. The complaint fails to put the defendant in the wrong. It does not state a cause of action, and the'judgment and order are therefore affirmed.
Affirrmd.
