¶1The place of seizure was the town of Hampden. The plaintiffs lived in Palmer. There were otljer deputies nearer, but the defendant especially desired and requested the plaintiffs to do the work, and promised to pay them. The case is here, after a finding for the plaintiffs by a judge without a jury, upon an exception to a refusal to rule that the contracts were without consideration and illegal. That broad question is the only one before us. It appears that the plaintiffs, at the defendant’s request, went to Springfield to get evidence upon which to found complaints, and advice as to the best manner in which to proceed in serving the warrants, and subsequently made complaints, obtained warrants, and served them. We must assume that the judge found that the defendant’s promises referred to the pre*296liminary or outside work and expenditures, and that the trips to Springfield recovered for fall within the promises as thus construed. No question is raised by the exceptions on these points.
¶2It follows that the exceptions must be overruled. The rule of law is simple. A contract to pay an officer for doing his official duty, or to pay him a sum in addition to his statutory fees, cannot be enforced. Pool v. Boston, 5 Cush. 219. Brophy v. Marble, 118 Mass. 548. Hatch v. Mann, 15 Wend. 44. But a contract is good to pay him for services outside the line of his duty for which the law allows him no fee. Davis v. Munson, 43 Vt. 676. Trundle v. Riley, 17 B. Mon. (Ky.) 396. England v. Davidson, 11 Ad. & El. 856. In Shattuck v. Woods, 1 Pick. 171, 175, it is said that, if an officer returns an execution unsatisfied by consent of the creditor and has incurred any expense, he must look to the creditor for his recompense.
¶3We cannot say that the plaintiffs have been allowed to recover for anything except their time, travel, and outlay in order to get information before filing the complaints. In Davisv. Munson, ubi supra, a deputy sheriff who went in pursuit of escaped prisoners and recaptured them was held entitled to a reward which had been offered. In these cases, as in that, the plaintiffs were under no “ specific official obligation ” to look up information, and apart from the defendant’s promises would have been entitled to no pay for their trouble or expense. It does not appear that what they did fell within Pub. Sts. c. 100, § 43, and it is unnecessary to consider what the effect of that section would be.
¶4Exceptions overruled.
