The policy issued by the General Exchange Insurance Corporation purports in express terms to be effective from noon, 28 April, 1928, to noon, 28 April, 1929. The car was burned 11 April, 1929. The policy, issued by the defendant on 2 April, 1929, contains this provision: “No recovery shall be had under section 1 of the schedule of perils if at the time a loss occurs thereunder there be any other insurance covering such loss, which would attach if this insurance had not been effected.” Both policies cover loss by fire and lightning.

The appeal, therefore, presents the question whether at the time the loss occurred the policy issued by the General Exchange Insurance Corporation was in effect. The appellants say in the first place, that it was void by reason of the transfer to the Hood System Industrial Bank of the lien on the car, no notice of the lien having been endorsed on the policy. The defendant contends that the policy should hot be declared of no effect on this ground. The existence of a lien in favor of the dealer or its assignees is acknowledged in the policy. The Pitt Chevrolet Company is the dealer and, apparently, the Hood System Industrial Bank is the dealer’s assignee. The note executed to the bank is described as the “extension of a note executed by W. M. Laughinghouse and endorsed by the Pitt Chevrolet Company and J. Knott Proctor on 24 November, 1928.” We do not perceive how the mere renewal or “extension” *436 of the note either increased the risk or diminished the security. As a rule the renewal of a security does not work the forfeiture of a policy which contains a condition against encumbrances. In Bowles v. Phœnix Ins. Co., 20 L. R. A., 400, it is said: “As the debt is unchanged the risk of the insurer is not augmented. The reason for the rule that the creation of an encumbrance in violation of the terms of the policy works a forfeiture has been thus stated: ‘It (the rule) goes upon the theory of an increased risk by reason of encumbrances. If a man may encumber his property to its full value and then insure it to its full value, it may be easily seen how it may be turned into a source of profit. Brown v. Commercial Mut. Ins. Co., 41 Pa., 187.’ ”

It is also contended by the appellants that the defendant waived the provision of the policy sued on respecting other insurance and that the defendant is therefore estopped to say that the appellants have forfeited their right to compensation. This position is based upon evidence tending to show that W. M. Laughinghouse exhibited to the defendant’s agent the policy issued by the General Exchange Insurance Corporation and said he had been informed by J. Knott Proctor that the policy was not in effect; that the defendant’s agent had an opportunity to examine it; and that he took from it the description of the property insured by the policy in suit. It is held that in the absence of fraud or collusion between the insured and the agent the knowledge of the agent, when acting within the scope of the powers intrusted to him, will be imputed to the company, though the policy contains a stipulation to the contrary. Short v. LadFayette Ins. Co., 194 N. C., 649; Ins. Co., v. Grady, 185 N. C., 348.

As we understand the record, the question whether the policy issued by the General Exchange Insurance Corporation is valid should be determined by the jury upon consideration of the evidence and if it is valid the question of waiver should likewise be submitted to the jury. It is insisted that estoppel or waiver must be pleaded, and as a rule this is true. Mfg. Co. v. Assurance Co., 110 N. C., 176; Clegg v. R. R., 135 N. C., 148, 154; Modlin v. Ins. Co., 151 N. C., 35; Shuford v. Ins. Co., 167 N. C., 547. But we are not prepared to say that the plaintiff’s allegations are too indefinite to justify the submission of an issue on this question.

In dismissing the action there is error for which a new trial must be awarded.
