The respondents instituted this action against the appellant to recover damages for an attachment alleged to have been procured to be levied against their property wrongfully, maliciously and without probable cause. The attachment issued on July 28, 1911, and was dissolved on January 13, 1913. The suit in which the attachment was procured was decided in favor of respondents and against appellant. The property alleged to have been attached consisted of moneys, corporate stock, notes, real estate and a motorcycle. Bespondents claim damages on account of being deprived of the use of the property and on account of loss of credit and profits in their business as building contractors. The ease was tried to a jury, which returned a verdict in respondent’s favor in the sum of $1,000. Judgment was entered accordingly, from which this appeal was prosecuted.
Appellant contends that the evidence fails to show that the property was attached. This contention is sustained so far as it concerns the real estate and the motorcycle. The return of the sheriff was offered in evidence by respondents to show what property was attached, but such return is only prima facie evidence of the truth of the matters therein stated. (Sec. 2026, Rev. Codes.) According to the testimony of respondents, the sheriff went to their office and informed them that the motorcycle was attached, but left it with them upon promise that they would not use it. The sheriff testified that although he was about to attach the motorcycle, he decided, at the request of respondents and with the consent of the attorney for appellant, to not do so. Without discussing the conflict of evidence in this particular, we hold that, assuming respondents’ testimony to be the truth in the matter, the sheriff did not levy upon the motorcycle in accordance with see. 4307, Rev. Codes (amended, Sess. Laws 1911, chap. 162, p. 559), because he did not, .at any time, take it into his custody or remove it from the custody of respondents. There is no levy under a writ of attachment unless the acts required by the statute are substantially performed. (First Nat. Bank v. Sonnelitner, 6 Ida. 21, 51 Pac. 993.) The uneontradicted testimony of the county recorder established the fact that no *397copy of the writ of attachment, or description of the real property alleged to have been attached, or notice of the attachment was ever filed in his office. Snch filing is absolutely necessary under the provisions of sec. 4307, supra, in order to constitute a lawful levy upon real estate. No action lies for an attachment procured maliciously and without probable cause unless the levy is complete. (Maskell v. Barker, 99 Cal. 642, 34 Pac. 340.)
The question of whether or not the real property was attached, and whether or not the notice and description and a copy of the writ of attachment were filed in the office of the county recorder, was submitted to the jury, but as there was •no evidence to dispute the testimony of the county recorder, that question should not have been submitted.
Appellant nest contends that the evidence was insufficient to show any damage resulting from the alleged attachment. Respondents rely upon injury to their credit and loss of prospective profits in their business as contractors, which are elements of damage if the attachment was not merely wrongful, but malicious and without probable cause. (Crymble v. Mulvaney, 21 Colo. 203, 40 Pac. 499; note to International Harvester Co. v. Iowa Hdw. Co., 29 L. R. A., N. S., 272; note to Tisdale v. Major, 68 Am. St. 263; note to Ailstock v. Moore Lime Co., 7 Ann. Cas. 545; 6 Corpus Juris, pp. 539-541, and cases in notes 76, 78 and 80; Shinn on Attachments and Garnishments, p. 693.)
Assuming that the evidence in this case supports the allegations that the attachment was issued maliciously and without probable cause, loss of profits and credit could be considered by the jury in awarding damage, but only upon such evidence being submitted as would enable it to calculate, with reasonable certainty, the amount of damage resulting from such loss. In this connection respondents introduced testimony tending to show that during the year previous to the issuance of the attachment the volume of business obtained by them was large and the profits amounted to about $3,000; that immediately after the attachment was dissolved their business and profits were about the same in volume, but that *398during the time the property was attached they performed wery little business and received little or no profits, although, generally speaking, there was as much building in progress in the locality in which they operated during that time as there was prior to or after the time the attachment was in force. They testified that because their property was tied up by the attachment they could raise no money, and could not obtain credit sufficient to enable them to advance the cost of material necessary to be used in construction work. They made no attempt to show that any certain contract for building could have been obtained by them had they been in a condition to perform it. The jury was left to infer from the fact that their business was of certain magnitude before and after the attachment, the volume during the time of attachment would have been the same. In the business of contracting, which is neither steady nor uniform, the profits received, or the amount of building done at one time is not a safe criterion by which to judge what might have been done at another had not the property of the contractor been attached. In case of a building contractor there is no such thing as uniformity in the volume of business. During one year he may have contracts for the construction of a few large buildings and during the next for many more, but smaller structures. If, however, respondents had shown that had they been able, financially, to handle them, they would have received certain building contracts, which they lost by reason of the attachment, then it would have been competent for them to show, upon the theory that the attachment was malicious and without probable cause, the cost of the labor and materials they would have used and the amount of the contract price, and thus furnish to the jury a safe and reasonable basis for the calculation of lost profits. “Past profits cannot be shown to enable a jury to conjecture what future profits would be.” (13 Cyc. 57; Bierbach v. Goodyear Rubber Co., 54 Wis. 208, 41 Am. Rep. 19, 11 N. W. 514.) Where recovery by reason of loss of profits may be had, there must be such evidence as will enable the jury, with some degree of certainty, to ascer.. tain the amount of the profits alleged to have been lost. *399(Central Coal & Coke Co. v. Hartman, 111 Fed. 96, 49 C. C. A. 244; Zinn v. Rice, 161 Mass. 571, 37 N. E. 747.)
The final question to be decided is whether or not the evidence was sufficient to show malice and want of probable cause. As heretofore stated, although actual damage may be recovered where the attachment was merely wrongful, yet to sustain a judgment for damage for loss of credit and profits, the attachment must be malicious and without probable cause. It is not alone sufficient that malice existed, nor is it sufficient that there is want of probable cause, but both these elements must be present. However, malice may be inferred by the jury, from the lack of probable cause (Ames v. Chirurg, 152 Iowa, 278, 132 N. W. 427, 38 L. R. A., N. S., 120; note to Tisdale v. Major, supra), but the jury cannot infer want of probable cause from the mere fact that the action in which the attachment was issued was decided against'the party procuring it. If the party suing out the writ of attachment had a reasonable belief in the existence of facts necessary to sustain the same, there was probable cause. (2 R. C. L. 899.) It is said that the test is what would prudent business men have done under like circumstances. (2 R. C. L., supra.) The burden is upon the party alleging malice and want of probable cause to prove the same. The evidence in this case shows that there was a dispute between the parties as to who was in debt to the other. Respondents had borrowed money from appellant and, on the other hand, were constructing a building for it. There was a dispute as to how much was due on the building. The books of appellant showed that respondents were in its debt to the extent of something over $1,000. There is no evidence tending to show malice or want of probable cause or, as a matter of fact, anything further than an honest misunderstanding between the parties as to which one owed the other.
Judgment is reversed and the cause is remanded for a new trial. Costs are awarded to appellant.
