The plaintiffs—six in number—-the defendant, and various other persons, seventeen in all, became sureties in several sums, upon the official bond of one Rogers, as Public Administrator of the County of San Bernardino. The complaint charges that afterward letters of administration in the matter of the estate of one Avaline, deceased, were duly issued to Rogers as such Public Administrator, and that on the same day, the latter entered upon the administration of said estate. That subsequently Rogers was removed, and one Pulwiler duly appointed administrator of the estate, and an order made directing Rogers to deliver to Pulwiler all moneys and other property in his hands belonging to the estate, among which was the sum of twenty-eight hundred dollars. That Rogers failed to pay over said sum, and that the sureties became liable therefor. For the plaintiffs’ cause of action the complaint then proceeds as follows: “ That on the (blank) day of September, A. jd. 1877, plaintiffs, and Peter Filance, William Hawley, M. Katz, J. A. Rosseau, (the last four named of whom are not parties to this action, but were sureties upon the bond) and defendant, agreed and promised that they would pay the said W. B. Ful wiler, administrator as aforesaid, the sum of twenty-eight hundred dollars; promising and agreeing, each with each and all the others, that they would so pay in proportionate rate, as the total original liability of said last-named persons, to wit, plaintiffs, and Peter Filance, Win. Hawley, M. Katz, J. A. Rosseau, and defendant, upon said of*108ficial bond of said Albert Rogers, to wit, thirteen thousand dollars, bore to the said sum of twenty-eight hundred dollars, so should the original liability of each upon said original bond bear to the sum each should pay. That defendant’s original liability upon said bond was the sum of two thousand dollars, and the amount of his proportionate rate of the twenty-eight hundred dollars, the sum of four hundred and thirty and ^ dollars gold coin. That on or upon the 1st day of December, a. d. 1877, plaintiffs paid, and fully discharged, the said sum of twenty-eight hundred dollars; and that afterward, to wit,- on or about the 25th day of December, 1877, and before the bringing of this suit, plaintiffs demanded of defendant his proportion of said sum so by them paid, to wit, four hundred and thirty 1'|)40 dollars, and that defendant has wholly refused and neglected to pay said sum or any part thereof.” Wherefore, the plaintiffs brought the present action to recover, and did recover, judgment against defendant for the last mentioned sum. After carefully considering the complaint, we are unable to discover that it states any cause of action in favor of the plaintiffs against the defendant. There is no averment that the defendant ever agreed to pay the plaintiffs anything, or that it was understood or agreed between the plaintiffs and defendant, or any of the parties mentioned, that the plaintiffs should pay to Fulwilcr the defendant? s pro rata share of the deficit, in consideration of which the defendant should refund to plaintiffs. This is not an action upon the bond, nor one for contribution, but the action is based upon the alleged contract of September, 1877, which, according to the allegations of the complaint, did not provide for the payment by the plaintiffs of the defendant’s pro rata share of the money due from the late administrator. The complaint failing to show any agreement or understanding by which the plaintiffs were authorized to pay the defendant’s part, pr any promise by the latter to repay, it fails to show any right in plaintiffs to recover what must be regarded, as the case is presented by the complaint, as a voluntary payment. No man can be a debtor for money paid, unless it was paid at his request. (Hilliard on Contracts, vol. 1, p. 71; 1 Parsons on Contracts, 6th ed. p. 471, and note “ F,” p. 273.) It follows that the judgment and order must be reversed, and the cause re-*109mantled, with directions to sustain the demurrer to the complaint. So ordered.
