The question for decision is whether or not the defendant insurer used due diligence to secure the cooperation of its insured to assist in the defense of an action for damages.
The defendant, hereinafter referred to as Farmers, wrote an automobile liability policy for one Ratzlaff. During the policy period Ratzlaff had a collision with one of the plaintiffs, Sjolund. Sjolund carried collision insurance with the plaintiff insurance company, hereinafter called State Farm. After State Farm paid Sjolund for the damages to his automobile, less the deductible, Sjolund and State Farm brought an action against Ratzlaff for the damage done to Sjolund’s vehicle. This action was tried and resulted in a judgment for the plaintiffs.
Such judgment was not satisfied and plaintiffs brought this suit against Farmers, as the liability insurance carrier of Ratzlaff. The suit was brought pursuant to ORS 736.320, which authorizes a suit against an insurer if a judgment against an assured is not satisfied within 30 days of the rendering of the judgment. Farmers alleged as an affirmative defense that it had no obligation under its policy because Ratzlaff had breached the terms of the policy by failure to cooperate in the defense of the damage action in that he failed to appear at the trial. The trial court entered a decree for the plaintiffs.
Failure to attend trial is usually deemed noncooperation on the insured’s part. See cases collected at 60 ALR2d 1146 (1958). The usual question, and the question here, is whether the insurer used due diligence to secure the attendance of the insured. In Johnson v. Doughty, 77 Or Adv Sh 253, 385 P2d 760 (1963), we stated our accord with the general rule that an insurer *288must use due diligence to secure the cooperation of its insured. We held in that case that the insurer had not used due diligence to secure its insured’s cooperation. In the Johnson ease there had been no communication between the insurer and the insured about any matter at any time. It was found that the only letter sent by the insurer to the insured had been sent to an address known to be incorrect.
The facts in this case are not as one-sided. On September 11,1959, a copy of the answer in the damage action was sent to Ratzlaff at his address in Eureka, California, where he had lived for sometime. An acknowledgment was requested, but none was received. The trial of State Farm and Sjolund against Ratzlaff was set for February 2, 1960, at Dallas, Oregon. On November 30, 1959, the attorneys appearing for Ratzlaff wrote Ratzlaff notifying him of the trial date and requesting him to acknowledge receipt of this notice. The letter was addressed to the same address in Eureka. No acknowledgment was received. On January 14, 1960, Farmers sent a letter to Ratzlaff by certified mail again notifying him of the trial date, stating the necessity for him to be present at the trial and offering to reimburse him for any expenses incurred in attending the trial, including loss of wages. An acknowledgment was again requested, but again none was received. Ratzlaff did not appear at the trial or notify Farmers that he was not going to appear. Ratzlaff’s attorneys moved for a continuance upon the ground that Ratzlaff was not present. Their motion was denied, and the attorneys continued to represent Ratzlaff at the trial.
The cooperation clause in the policy issued to Ratzlaff was as follows:
“The insured shall cooperate with the Exchange *289and, upon the Exchange’s request, shall attend headings and trials and shall assist in affecting settlement, securing and giving evidence, obtaining the attendance of witnesses and in the conduct of suit.”
If this were an ordinary commercial bilateral contract between two parties for whom a continuous relationship during the term of their agreement was mutually advantageous, Eatzlaff probably would be held to have breached his contractual duty. If a party to an ordinary contract is notified by mail that, under the terms of the contract, he is now required to perform an obligation assumed by him in the contract, such notification is usually sufficient. A failure to perform after such notification would amount to a breach of the contract unless some legal excuse for nonperformance is shown. The party whose performance was not forthcoming would have the burden of explaining his default. The presumption would arise that a letter duly directed and mailed to the addressee at his last known address was received by him. ORS 41.360(24).
Notification by mail to the insured in an automobile liability insurance contract that he must now perform a duty he undertook by contract may not be sufficient.
The motivation of an insurer and an insured may be very different from the motivation of the parties to the usual contract. In the usual contract it is to the promisee’s benefit and advantage to have the promisor perform his contractual duties. If there is any indication that the promisor is not going to perform, the promisee will exert great effort to secure performance. If performance is not secured, the benefit the promisee hoped to gain from entering into the contract is lost. There is no need to impose a legal duty on the promisee *290to use diligence to secure the promisor’s performance; the economies of the bargain provide ample incentive. The only legal duty that must be inferred, if it is not expressed in the contract, is the duty to notify the promisor that the contractual prerequisites upon which his performance was conditioned have now occurred.
In an insurance contract the benefit to the promisee, the insurer, may be gained in exactly the opposite manner from that existent in the usual contract, i.e., the insurer benefits if the promisor fails to perform. If the promisor, the insured, fails to perform his duty to cooperate, the promisee gains the ultimate benefit; it does not have to pay a loss. There is no economic incentive for the insurer to expend any effort to secure the insured’s performance.
The promisor-insured’s motivation may also be very different from that of the usual contractual promisor. The usual promisor hopes to gain a benefit or avoid a detriment by performing. Again, the economics of the bargain usually provide enough incentive to guarantee performance and, if this is insufficient, the financial consequences of a breach of contract supply an additional goad.
This motivation is usually wholly lacking when difficulty is encountered in securing the cooperation of an insured. Insureds, when uncooperative, usually become so because they cannot see how their cooperation would benefit either themselves or their insurance company. If the insured was a witness to the accident and believes that on trial he will be found to be at fault, he may see no reason why he should be at the trial. If he was not a witness to the accident, he likewise may see no reason why he should be at the trial. Regardless of his attitude about the above matters, if the *291insured is judgment proof, lie may see no pecuniary benefit accruing to him from attending the trial. The type of person most likely to be indifferent to his duties under the insurance contract is frequently the type of person least likely to be concerned about a judgment being obtained against him.
This situation presents the temptation and the opportunity to the insurer to create a defense to what otherwise would be an indefensible claim, particularly when the insured is believed to reside some distance away from the place of trial. The disinterested attitude of the insured becomes known to the claims man handling the claim. (This was obvious here as the insured on two occasions failed to notify the insurer of the service of summons on him in this action until long after service.) The claims man forms the opinion that this particular defendant may not respond to impersonal, routine communications such as by letter. The insured may not respond to a personal urging by a representative of the insurer either, but if the law does not require some degree of diligence, the insurer has no incentive to do more than “go through the motions.” If the insurer sends a letter to the insured notifying him of the trial date, and the insured does not appear, what initially may have appeared to be a case involving a certain loss to the insurer in some amount conveniently turns into a case with an airtight defense.
We are not inferring that the insurance industry makes this a trade practice. The fact that this appeal and Johnson v. Doughty, supra, are the first two cases in this court involving this problem is proof it does not. However, the temptation and opportunity inherent in this situation is a factor to be considered in determining the scope of the duty to use due diligence.
*292If a situation of the kind described only involved the loss by an insured of the indemnity he purchased under his insurance contract, the possibility envisioned above would not concern us. As noted, the typical uncooperative insured is judgment proof. Indemnity is only of academic concern in such eases. However, while such an insured is nominally the important party, he has no real interest in the outcome; the injured party has the real interest. The injured party is at law only a subrogee of the insured, but in the usual noncooperation case the injured party has the substantial interest, and the interest of the insured is only superficial. The appearance of the insured may be all-important to the defense of the action, but the losing, winning or paying of a judgment ordinarily does not concern the noncooperating insured.
This court and the Oregon Legislature have recognized this interest of an injured party. In In re Vilas’ Estate, 166 Or 115, 135, 110 P2d 940 (1941), this court stated:
“The public policy of this state is to protect as far as possible those injured through the carelessness or negligence of motor vehicle operators who make use of its highways. * * *”
The Oregon Legislature by the Financial Responsibility Act, ORS ch 486, largely abolished any insurance policy defenses, including the defense of noneooperation, when an action is brought by an injured party against an insurer. That act, however, only applies to policies issued as proof of financial responsibility. ORS 486.550. Again, in another context, the legislature has required that all automobile liability policies contain a provision insuring policyholders against loss by reason of injuries inflicted by an uninsured motorist. *293OES 736.317. These legislative declarations reflect a governmental policy in favor of protecting the innocent victims of vehicular accidents even though the tortfeasor may have been totally indifferent to the rights of others.
For these reasons we conclude that standards governing ordinary bilateral contracts do not necessarily govern an insurer’s obligation to use due diligence to secure the cooperation of its insured. We are not holding, however, that an insurer, issuing a policy not required as proof of financial responsibility, can never assert successfully the defense of noncooperation. We are holding that an insurer must make a substantial showing of diligence before it can successfully rely on the defense of noneooperation.
Before it can be determined whether Farmers used due diligence here, it must first be determined whether this is a suit in equity or an action at law. In the former, the case is tried de novo.
We hold this is an equitable proceeding in the nature of a creditor’s bill. The prayer of the complaint was for an order requiring Farmers to satisfy plaintiff’s judgment against Ratzlaff. The proceeding was an attempt by a judgment creditor to reach an asset of the judgment debtor. “* * * where a creditor seeks to satisfy his debt out of some equitable estate of the defendant [judgment debtor] in the suit which is not liable to levy and sale under an execution at law,” it is a type of creditor’s suit. Security S. & T. Co. v. Portland F. M. Co., 124 Or 276, 303, 261 P 432 (1928). In the case of In re Vilas’ Estate, supra (166 Or 115), the contractual liability of an insurance carrier to the deceased insured was held to be an asset warranting the appointment of an administrator in the county in *294which, the insured did business. Such an asset is equitable, rather than legal, because it is not liable to levy and sale by an execution at law. Note, Foundation for a Creditor’s Bill in Oregon, 36 Or L Rev 338 (1957).
The fact that it can be reached by garnishment, an action at law, does not necessarily deprive equity of jurisdiction. Sabin v. Anderson, 31 Or 487, 494, 49 P 870 (1897); Matlock v. Babb, 31 Or 516, 49 P 873 (1897). The rule of these decisions is that pre-existing equitable jurisdiction is not taken away by legislative creation of a remedy at law, such as garnishment, unless the legislature specifically so provides. Plaintiff here is proceeding under ORS 736.320, which provides:
“* * * if such judgment [against an assured] is not satisfied within 30 days after it is rendered, then such person or his legal representatives may proceed against the company to recover the amount of such judgment, either at law or in equity, * * (Emphasis added.)
This is a clear statement that an injured party may use any equitable remedies that are otherwise applicable, such as a creditor’s suit. See Note, 9 Or L Rev 58-59 (1929), for decisions permitting the use of creditors’ suits against liability insurance carriers. See decisions noted in 8 Appleman, Insurance Law and Practice, 247, § 4838.
Trying this as an appeal de novo, we find that the defendant did not use due diligence in attempting to secure the attendance of Ratzlaff at the trial of the damage action.
It is difficult to state any specific principles concerning what does or what does not constitute an exercise of due diligence. All we shall attempt here *295is to state the evidence, or lack of evidence, that caused us to reach this decision.
All the circumstances here warned that Eatzlaff’s cooperation was not going to be a matter of course. The accident was in May, 1953, more than six years before the trial date. Automobile collisions with no personal injuries dim in importance as they grow ancient. In June, 1955, attempted service in State Farm v. Ratzlaff was made on Eatzlaff in Eureka. He did not send the summons and complaint to Farmers until its representative contacted him over two years later in September, 1957. The default judgment entered by reason of this service was set aside, and he was served again in March, 1959. The papers then served were not turned over to Farmers until more than 90 days after service. Despite a request he failed to acknowledge letters sent to him by Farmers and by Eatzlaff’s attorneys, engaged by Farmers, in September and November, 1959, and January, 1960. It should not have been surprising when he did not appear at the trial in response to the January letter requesting him to appear.
On July 30, 1959, Farmers had Eatzlaff execute a Eeservation of Eights Agreement. The agreement recited that Farmers “considers that it would not be responsible for any judgment rendered,” but Farmers agreed to defend him if he would cooperate. This agreement is significant in two respects. It appears that a representative of Farmers personally contacted the insured at his address in Eureka and supervised the execution of the agreement. The inference is that when the insurer desired the insured’s cooperation for the insurer’s benefit, acquiescence in the insurer’s denial of protection, personal contact could be made, and such contact was effective in obtaining the in*296sured’s cooperation. When the insured’s cooperation was not to the insurer’s benefit, it relied upon letters, not personal contact. It should not be assumed that in every case personal contact is essential to an exercise of due diligence. However, in this case, under all the circumstances, the absence of an attempt to have a representative of the insurer personally attempt to secure the insured’s presence at trial is damaging to defendant’s defense.
Farmers denied any liability to Ratzlaff by the Reservation of Rights Agreement. Under some circumstances a denial of liability by the insurer terminates any duty of the insured to cooperate. See cases collected at 70 ALR2d 1197, 1201 (1960), and 49 ALR2d 694, 759 (1956). iSuch is not the case here, but denial of liability would certainly dull the insured’s incentive to cooperate, and, therefore, more diligence would be necessary to attempt to secure his cooperation.
Ratzlaff’s version of the collision is not in evidence. We may assume Farmers obtained his statement. The answer filed for Ratzlaff denies his negligence and alleges contributory negligence upon 'Sjolund’s part. However, the answer was not verified by Ratzlaff. The absence of Ratzlaff’s statement leaves us in doubt as to whether his testimony at the trial would have helped or hindered his defense. Its absence creates the suspicion that it was unfavorable to Ratzlaff. The importance of this is that if an insured’s version of the accident is unfavorable to him, and, therefore, to his insurer, we would more closely scrutinize the insurer’s efforts to secure the presence of the insured.
The defendant alleged the affirmative defense of noncooperation by Ratzlaff, its insured. To maintain successfully such a defense it must bear the burden of *297proving that it used due diligence in securing such cooperation. As the trier of fact upon an appeal de novo we find it did not prove that it used due diligence.
The defendant also contended that the trial court erred in not considering certain evidence. Inasmuch as we have tried the case de novo and reached the same decision that the trial court did, it is not necessary to consider this.
Affirmed.
