Mr. Justice Craig

delivered the opinion of the court:

In the decision of this case we do not deem it necessary to follow counsel in their long argument, or to enter upon an extended review of the many authorities which have been cited in the briefs. To do so would extend this opinion to an unreasonable length, and result in no substantial benefit to either of the parties.

As has been seen, Prank Hebner applied for insurance on the propeller, and the boat was insured in his name, as his property. The propeller was worth, at the time the loss occurred, $15,000. The loss was fixed at the sum of $9857.10. At the time the policies were issued Prank Hebner was not the sole owner of the propeller. He owned only one-half, and the other half belonged to W. P. and J. S. Botsford. But this fact was not disclosed to the insurance companies. It appeared, however, from the evidence, that at the time the insurance was effected the propeller was in the possession of and under the control of Hebner, and that he had agreed with the Bots-fords to keep her insured. The policies contained the following provisions:

“First — This entire policy shall be void * * * if the interest of the insured be other than unconditional and sole ownership.

“Second — This entire policy shall be void if the insured has concealed or misrepresented any material fact concerning this insurance or the subject thereof, or if the interest of the insured in the property be not truly stated herein.”

Notwithstanding these provisions in the policies it is claimed, on behalf of the appellant, that he is entitled to recover the entire loss, less his proportionate share of raising the vessel.

It may be conceded that it was entirely competent for Hebner, had he so desired, when the contract of insurance was made, to not only insure his own interest in the propeller, but also the interest of the other two owners. But no language will be found in the policies indicating any intention whatever of the contracting parties to insure property owned or possessed by any person other than Hebner. It will be observed by going to the policies, which constitute the contract between the parties, that Hebner was not insured as to any part of the vessel as manager, trustee or agent, nor was he insured against loss on property held by him as agent, in trust or as manager for some other person, as he might have been, and the law which controls cases of that character can have no bearing here. The contracting parties, Hebner and the insurance companies, agreed that if the interest of the insured be other than sole ownership the policies shall be void. This was the contract of the parties, deliberately made, and the question is whether that contract shall control, or shall some other contract never made be enforced.

The law as laid down by the authorities, as we understand it, is : Where the policy contains a provision that the insured is the unconditional and sole owner of the property, and it turns out the insured was not the unconditional and sole owner, no recovery can be had, unless it appears there was a waiver or an estoppel, by which the insurance company is precluded from relying on the contract. May on Insurance, (3d ed.) sec. 287; Southwick v. Atlantic Fire and Marine Ins. Co. 133 Mass. 457; Brown v. Com. Ins. Co. 86 Ala. 186; Farmville Ins. Co. v. Butler, 55 Md. 233 ; Fuller v. Phœnix Ins. Co. 61 Iowa, 350 ; Fire Ins. Co. v. Weaver, 70 Md. 536; Finney v. Bedford Ins. Co. 8 Metc. 348.

The case last cited is like the present case, except that the agent knew, when the policy issued, the condition of the title. It is there said: “The question here presented is not as to the competency of John S. Bates to effect an insurance for the benefit of all his associates who were interested in the property which was the subject of insurance, but whether, upon the face of the policy and the terms of this contract of insurance, the legal effect is not to restrict the insurance to the sole interest of Bates. It may at once be conceded that it was competent for Bates to effect such insurance on the entire interest of all concerned if either previously authorized by the co-owners or if they elected to ratify his act, even after the loss. But the appropriate form of the policy in such case is ‘for himself and other owners,’ or ‘for whom it may concern,’ or other words indicating that the insurance is to embrace an interest beyond that of the party in whose name the policy is issued. * * * But the real question here is, whether a policy made in the name of a particular person who is the owner of a small proportion, in interest, of the property insured, without any words indicating an intention to insure beyond his own interest, can be made effective to cover the interest of others upon parol proof that the application for insurance was for such others as well as for the party named, and that this was well known to the insurers, and that it was the intention and understanding of the parties that the policy was to cover the interests of all the owners. * * * When the parties have put their agreement into writing, and the terms of it are plain and di-. rect, leaving no uncertainty as to the nature of it, we must treat it as the whole engagement of the parties. * * * The evidence proposed in the case at bar was incompetent and the verdict for the defendant was properly ordered.”

The case in 61 Iowa is quite similar to the case under consideration. In the decision of the case it is, among other things, said: “It is contended that Ashem had an insurable interest in the property of plaintiffs. This proposition may be conceded for the purposes of this case. We do not think it is material whether he had an insurable interest or not, because the fact remains that according to the terms of this policy he insured no property but his own; and in order to include the property of the plaintiffs in the policy it is necessary to show that it was included, either by proof of a waiver of the conditions of the policy or by proof that a different contract was actually made than that which is expressed in the policy. There are many adjudged cases which hold that certain conditions of a policy of insurance may be waived by parol. These cases include such provisions as the time of the payment of premiums, the production of proofs of loss, the breach of any condition in the policy as against the increase of risk, or the keeping of hazardous goods, or the like. (See cases cited in Wood on Ins. 832.) In this court it has been held that an increase of risk may be waived by an agent by parol. (Viele v. Germania Ins. Co. 26 Iowa, 9.) That the time for payment of the premium may be waived. (Young v. Hartford Ins. Co. 45 Iowa, 377.) Other cases of waiver of conditions need not be stated. In the case at bar we are asked to go a step further than any case to which our attention has been called, and hold that the conditions of a policy as to the subject of the insurance — the property insured and the ownership thereof — may be waived by parol. In other words, we are called upon to allow the plaintiffs to maintain an action upon a policy in which they are not named, and which, by its very terms, excludes all property except such as was owned by Ashem in his own right.”

In the case cited from Alabama, supra, it is said: “Where the true ownership is not required to be fully stated by the conditions of the policy, generally, it will be sufficient if the assured has an insurable interest; but when such requirement is the condition of the policy it becomes a material part of the contract, and all rights under it are forfeited by non-compliance. * * * By express stipulation the parties make it material, and the validity of the contract is dependent on a compliance with the condition. The assured, by accepting a policy in which such condition is incorporated, becomes bound thereby, and when he claims to enforce the contract and receive its benefits he is estopped from denying his assent to the stipulation.”

There are many other cases where the same doctrine has been announced, but it is not necessary to make quotations from them. Indeed, this court in Reaper City Ins. Co. v. Brennan, 58 Ill. 158, in effect laid down the same rule.

On the trial the defendants, through their attorneys, stated to the court that although not liable they were willing to pay plaintiff, as half owner of the vessel, one-half the amount of the loss, less the expense of raising the vessel and placing her in proper condition. Under this agreement a judgment was rendered for §2597.15, — • one-half the loss after deducting the amount paid by defendants for raising the vessel. It is, however, claimed that the court erred in deducting the cost of raising the vessel. The policies provide that if fire occur the assured shall protect the property from further damage ; that he shall separate the damaged and undamaged personal property, and that he shall put the property in the best possible order, and that within sixty days he shall make proofs of loss. Under the policy we think it was the duty of Hebner to raise the vessel at his own expense and protect it from further damage. He applied to the insurance companies to raise the boat for him. This they did at §400 less expensé than he was able to do, and we see no reason why the amount should not be deducted.

The judgment of the Appellate Court will be affirmed.

Judgment affirmed.
