The sole question before us is whether the plaintiff is the real party in interest in this suit against a third party or has lost that status by reason of entering into the loan agreement with his insurer. The loan receipt and agreement detailed the claim, disclaimed liability, and re *594 cited the reasonableness of compromise settlements, the financial inability of the plaintiff, and the casualty company’s desire to make a loan for the purpose of making the settlements. The agreement provided the loan did not satisfy any obligation of the company to the plaintiff and was repayable only to the extent of recovery by the plaintiff from third parties by way of contribution, indemnity, subrogation, or other means. The plaintiff agreed to commence all actions requested by the casualty company but at its expense and under its control and not to settle or compromise any claim without the consent of the casualty company. All moneys collected by the plaintiff were to be turned over without demand to the casualty company and applied in satisfaction of the loan. The agreement was silent as to interest and provided the plaintiff waived no rights against the casualty company and the casualty company did not obtain any right to prosecute any claim in its own name against strangers to the agreement and waived any right of contribution, indemnity, or subrogation, except its right to have the loan repaid to the extent of any recovery by the plaintiff.
The casualty company does not seriously argue this loan agreement creates in fact a customary loan but it does contend the agreement constitutes a valid and legitimate means of settling claims and lawsuits in an expeditious manner and of avoiding extensive litigation. These purposes it is argued justify this court considering the plaintiff the real party in interest in fact as well as in form within the meaning of sec. 260.13, Stats., which provides every action must be prosecuted in the name of the real party in interest.
Whether or not the plaintiff is to be considered the real party in interest in this suit to be indemnified by Chick depends upon the nature of the transaction between the plaintiff and the casualty company. If the transaction was a
*595
payment although called a loan by the casualty company, the plaintiff is not the real party in interest because any rights he had against Chick belonged to the casualty company by virtue of subrogation. The form of a transaction if inconsistent with its substance is not controlling. This court on other occasions has construed the form of documents to be overridden and controlled by the substance of the transaction. Two notable examples are construing a warranty deed as a mortgage and of joint tenancies in form as not being joint tenancies or as being tenancies in common.
Barr v. Granahan
(1949),
The loan receipt and agreement has a propér and legitimate place in the adjustment of losses under insurance policies but the device is unavailable and improper in this state to cover up a suit based on subrogation or to obtain the same results as the enforcement of subrogation rights. The court will not recognize the transaction as a loan if the insurer’s right to demand repayment of the loan is in substance its right to subrogation parading in disguise. However, to expedite prompt settlement of claims against insurance companies the loan-agreement device has been recognized when payment would be prejudicial to the insurance company under the terms of its policy.
The leading case upholding the validity of a loan-receipt agreement is
Luckenbach v. McCahan Sugar Co.
(1918),
Some subsequent cases citing Luckenbach have lost sight of the fact the loan agreement therein involved was in fact intended to be a loan and was justified under the circumstances that the insurer’s liability was contingent in effect upon the nonliability of the carrier. Many of these cases are cited and commented upon in Anno. — Insurance — Loan Receipts, 157 A. L. R. 1261. In Bolton v. Ziegler (D. C. Iowa 1953), 111 Fed. Supp. 516, apparently all of the cases decided up to that time and the literature by way *597 of text and law review articles in any way relating to loan receipts and agreements are collected. The cases are grouped under various classifications without, however, any critical analysis. The case, however, holds that the loan agreement used was invalid as an attempt to secure contribution between joint tort-feasors which was not permitted in Iowa whose substantive law governed the facts.
We do not say that all policy or coverage defenses may justify the use of the loan receipt; but, where the liability under the terms of the indemnity or liability policy is contingent, loan receipts and agreements have been sustained as not being payments in fact. In another class of cases akin to
Luckenbach,
loan receipts and agreements have been upheld in order to avoid or eliminate any contention or possibility that a void insurance policy was valid, which might be the case if payment were made. This class of cases is illustrated by
Kossmehl v. Millers National Ins. Co.
(1945),
*598
Another type of case in this class in which the loan agreement is justified arises when an insurer has a policy which provides only excess insurance.
Young v. Drive-It-Yourself, Inc.
(1961),
The use of a loan receipt and agreement as a substitute for a subrogation suit was struck down in
American Alliance Ins. Co. v. Capital Nat. Bank
(1946), 75 Cal. App. (2d) 787,
On the other hand there are cases supporting the position of the appellant that the use of the loan-agreement device is justified in cases to avoid subrogation in form. The justification in this class of cases is to protect the insurers by nondisclosure from the prejudice of juries against insurance companies especially in subrogation cases.
Merrimack Mfg. Co. v. Lowell Trucking Corp.
(1944),
Wisconsin has no such statute and the reasoning of the Merrimack Case has no justification here at least in regard to automobile accident cases because in such cases insurers may be sued directly by the injured party. Secs. 260.11 and 204.30 (4), Stats. In fact if an insurer could use the loan-receipt device to avoid subrogation in Wisconsin it would receive an advantage because while its identity could thus be hidden it could expose the identity of the insurer of the third party.
*600 The appellants in their reply brief attempt to argue the casualty company’s liability was contingent and not absolute. The argument fails to convince us that the loan transaction was entered into because of any contingent liability under the terms of the policy nor does the record disclose any such reason. Perhaps the liability was undetermined but that is not identical with being contingent. Nowhere in the loan agreement, which elaborately states the reasons for making it, is there any claim the loan receipt was used for any other purpose than to reimburse the casualty company for the money it claimed it loaned. On the facts presented, we cannot find the parties intended this to be a loan and not a payment, but assuming the insurer can intend and make this type of loan, it is not a valid device for the indirect enforcement of subrogation rights so that the insurer receives back money by way of recoupment.
The two Wisconsin cases cited by the casualty company are not to the contrary. In
Liner v. Mittelstadt
(1950),
By the Court. — Judgment affirmed.
