The policy of fire insurance involved in this case contains these provisions: “It is a condition of this policy that it shall be null and void if the interest of the assured in the property be other than unconditional or sole ownership, or if the subject of this insurance be or become encumbered by any lien or mortgage except as otherwise endorsed hereon. . . It is a condition of this policy that failure on the part of the assured to render such sworn statement of loss to this company within sixty days of the date of loss (unless such time is extended in writing by the company) shall render such claim null and void. . . No officer, agent, or other representative of this company shall have power to waive any of the terms of this policy, unless such waiver be written upon or attached hereto, nor shall any privilege or permission affecting the insurance under this policy exist or be claimed *649by the assured unless so written or attached.” The insured notified the agent of the insurer, with whom the policy had been left by the insured for safe-keeping for the insured’s benefit, of his intention to encumber the property with a mortgage or bill of sale as security for a loan, and requested the agent to make the necessary entry and indorsement in writing upon the policy to permit such encumbrance. The agent assured the insured that this would be done. The policy remained in the hands of the agent. Relying upon the agent to carry out such instructions, and without knowledge that such instructions had not been carried out, the insured encumbered the property. The agent failed to make any written indorsement or to attach any writing to the policy permitting such encumbrance. Under the above circumstances is the insurer, as a matter of law, estopped from defending against the loss under the policy upon the ground that permission to the insured to en-cumber the property insured had not been indorsed upon the policy, nor had any writing been attached thereto permitting such encumbrance; and would a jury be authorized to find that the insurer was so estopped?
There is great diversity of opinion as to the effect to be given to the provision of this policy last above quoted. One group of decisions tends to favor the insurer, by adhering to a strict and literal constructiqn of this stipulation. The other group, leaning to the insured, tends to nullify the effect of such provisions. 32 C. J. 1318, § 570. But in this State this provision of the policy is valid and binds the insured. Morris v. Orient Ins. Co., 106 Ga. 472 (33 S. E. 430); Lippman v. Ætna Ins. Co., 108 Ga. 391 (supra); Athens Mutual Ins. Co. v. Evans, 132 Ga. 703 (64 S. E. 993); Beasley v. Phoenix Ins. Co., 140 Ga. 126 (78 S. E. 722); Nowell v. British-American Assurance Co., 17 Ga. App. 46 (85 S. E. 498); McAfee v. Dixie Fire Ins. Co., 18 Ga. App. 192 (89 S. E. 181); Long v. Hartford Fire Ins. Co., 25 Ga. App. 24 (102 S. E. 379). But the insurer may be estopped from relying upon this provision as a defense to an action for the recovery of a loss under its policy of insurance. Under the circumstances recited in the first question propounded by the Court of Appeals, we think the insurer would be estopped from defending against a loss under the policy. If the insurer or his authorized agent consents to changes, permission to make which is required to be in*650dorsed on the policy, and promises to make the necessary indorsement, having access to the policy for this purpose, upon which promise the insured relies and acts, but the agent fails to make the indorsement, through mistake, oversight, neglect, or fraud, the insurer will nevertheless be bound, if not by waiver, at least by an estoppel in pais. 3 Cooley’s Briefs on Law of Insurance, 2617; Manchester v.

But it is said that this court has ruled to the contrary of what is said above; and to sustain this contention the insurer relies upon the cases of Simonton v. Liverpool &c. Ins. Co., 51 Ga. 76, Lippman v. Ætna Ins. Co., 108 Ga. 391, Johnson v. Ætna Ins. Co., 123 Ga. 404, Athens Mutual Ins. Co. v. Evans, 132 Ga. 703, and Beasley v. Phoenix Ins. Co., 140 Ga. 126 (supra). The case at bar is distinguishable from these cases. In Simonton v. Liverpool &c. Ins. Co., the insured had a policy on their stock of goods in a certain house on a certain street in Atlanta. They concluded to remove them to a different house in a different place in the city. They had actually commenced removing this property. While engaged in so doing an agent of the insurer, noticing that they were removing their stock, notified them that the removal would vitiate *651their policy unless they desired it continued and the company agreed to it. The insured said they did desire it, and the agent said that his company would agree, and that he would fix it upon the books accordingly. The insured alleged that, relying upon this, they removed their goods, took out no new policy, supposed they were duly insured at their new place, and that their goods were destroyed by fire. Under, these circumstances this court held that the insured had failed to make out a case of equitable estoppel, which would have been necessary in order to meet the requirement of our law that a policy of insurance must be in writing, in consequence of which any alteration thereof must be in writing. This court held that the facts of that case showed that the insured did not remove their goods relying upon a statement of the agent of the insurer, but that they were removing and would have removed them without such an agreement. The removal of the goods by the insured was not done in performance and in pursuance of the parol contract. Furthermore, this court said that there was very little in the language of the agent to justify the insured in relying thereon. “The words are consistent,” said Judge McCay, “with an understanding on his part that, as the policy required, they should bring their policy to the office where the entry of agreement would be made.” In that case the agent did not have possession of or access to the policy of insurance, and he made no agreement to indorse thereon or attach thereto permission for the insured to remove their goods. In Lippman v. Ætna Ins. Co., Johnson v. Ætna Ins. Co., Athens Mutual Ins. Co. v. Evans, and Beasley v. Phoenix Ins. Co., the insured relied upon oral permissions of agents to do certain things which their policies provided such agents had no authority to grant, unless such permissions were in writing and indorsed on the policies. In these cases the agents did not have possession of or access to the policies of insurance. They did not agree to make the indorsements upon the policies. For these reasons these cases are clearly distinguishable from the case at bar. In like manner the cases of Nowell v. British-American Assur. Co., 17 Ga. App. 46, McAfee v. Dixie F. Ins. Co., 18 Ga. App. 192, Long v. Hartford F. Ins. Co., 25 Ga. App. 24 (supra), and Bruce v. Hartford F. Ins. Co., 31 Ga. App. 116 (120 S. E. 13), can be distinguished on similar grounds. We cannot agree to so much of the decision in Sparks v. National *652Union F. Ins. Co., 23 Ga. App. 38 (supra), as seems to hold to the contrary of what is ruled above.
The ruling we make is based upon the doctrine of equitable estoppel. If an agent of the insurer, authorized to make the necessary indorsement on a policy permitting the insured to encumber the property thereby insured, and having access to the policy, upon application of the insured for the indorsement of such permission upon his policy promises him to make such indorsement, and upon this promise the insured relies and acts, with notice to such agent that the insured is so relying and acting, and the insured thereafter sustains loss under his policy, the insurer shall be estopped to set up the defense that such indorsement had not been actually made upon the policy. There are authorities to the contrary, but the trend of modern decisions is toward the ruling which we make in this case. So we are of the opinion that the main division of the first question propounded by the Court of Appeals should be answered in the affirmative.
Under the facts set out in subdivision (a) of the first question, we think that a jury would be authorized to find that the insurer was estopped. The fact that the cashier of the bank making the loan to the insured, for which purpose the latter wished authority indorsed upon the policy, was- also agent 'of the insurer, would not alter the case. Clay v. Phoenix Ins. Co., 97 Ga. 44 (25 S. E. 417).
Do the facts stated in the second question propounded by the Court of Appeals amount as a matter of law to a waiver by the insurer of its right to insist upon the filing by the insured of proofs of loss in the time prescribed in the policy, and prevent the insurer from setting up the failure of the insured to make proof of loss within a prescribed time, as a defense against the suit by the insured to collect the loss under the policy ? In Underwriters Agency v. Sutherlin, 55 Ga. 266, this court held that an adjuster could not, without express authority from the managing officers of the insurer, waive a stipulation in the policy of insurance that no action for loss thereunder could be sustained unless commenced within twelve months after such loss occurred. This case is not authority for the proposition that an adjuster cannot waive proofs of loss within the time in which the insured was required to make such proofs. In Lippman v. Ætna Ins. Co., 120 Ga. 247 (47 *653S. E. 593), this court held that “a forfeiture of a contract of insurance cannot be waived by a local agent of an insurance company, without express authority from the governing officials of the insurance company.” Here this court was dealing with the forfeiture of a policjr which had already taken place, and not with the authority of an adjuster to waive proofs of loss under a policy in full force when such waiver was made. In Farmers Mutual Fire Asso. v. Steed, 20 Ga. App. 329 (93 S. E. 75), the Court of Appeals was dealing with the authority of the agent of the insurance company to waive the forfeiture of the policy caused by the failure of the insured to comply with the terms of the iron-safe, clause embraced in such policy. That case does not authorize the holding that the adjuster could not waive proofs of loss under the facts set out in this question. In Athens Mutual Ins. Co. v. Evans, 132 Ga. 703 (supra), this court was dealing with the authority of an agent to give oral permission to the insured to encumber the property insured by a security deed, when the policy of insurance contained provisions that such encumbrance would render the policy void, and that no agent of the company had the power to waive such provision except by agreement indorsed thereon or attached to the policy. That case does not furnish a basis for the contention that an adjuster, under the provision of this policy, could not waive proofs of loss. In Williams v. Atlas Assur. Co., 22 Ga. App. 661 (97 S. E. 91), the Court of Appeals held that under this limitation “an agent’s notice of refusal to pay the loss would not bind the company as a waiver on its behalf of the contractual duty of furnishing the proofs of loss called for by the terms of the contract of insurance.” Johnson v. Ætna Ins. Co., 123 Ga. 404 (supra), was cited as authority for this ruling. We submit that the cited case, properly construed, does not justify the ruling made. In the cited case this court properly held that “Limitations in an insurance policy upon the authority of the agent of the company to waive the conditions of the contract of insurance are to be treated as referring to waivers made subsequently to the issuance of the policy;” but this court did not have before it in that case the question of the power of an adjuster to waive proofs of loss within the time in which the insured had the right to make them. In Williams v. Atlas Assur. Co., supra, the Court of Appeals recognized that an absolute refusal to pay, *654made by an authorized agent of the insurer, would waive the requirement of proofs of loss, notwithstanding the provision limiting the authority of the agents and officers of the insurer, and quoted in support of this ruling the case of Continental Ins. Co. v. Wickham, 110 Ga. 129 (35 S. E. 287).
In Folds v. Fireman’s Fund Ins. Co., 28 Ga. App. 323 (110 S. E. 925), the Court of Appeals held that an adjuster could not waive proofs of loss unless such waiver was written upon or attached to the policy. In- support of this proposition the court cited, among other authorities, the case of Metropolitan Life Ins. Co. v. Caudle, 122 Ga. 608 (50 S. E. 337), but an examination of that case will show that it does not support this view. This ruling by the Court of Appeals is not in harmony with the great weight of authority. “By the weight of authority, an officer or agent otherwise having authority to waive notice or proofs of loss may bind the company by an oral or implied waiver, notwithstanding a stipulation in the policy that no officer or agent shall have power to waive any of its terms or conditions unless the waiver is in writing indorsed on the policy or attached thereto.” 33 C. J. 24, § 681, and cases cited in note 10 to this section. Clauses in insurance policies which prohibit waivers unless indorsed thereon refer only_to_the provisions which enter into the contract of insurance, and do not affect conditions which are to be performed after loss, such as furnishing proofs of loss and giving notice. These may be expressly waived, or may be waived by conduct inconsistent with an intention to enforce a strict compliance with the condition, by which the insured is led to believe that the insurer does not intend to require such compliance.

L. 1345.
An adjuster sent to adjust a loss presumably has authority to waive proof of loss. Slater v. Capital Ins. Co., 89 Iowa, 628, 57 N. W. 422 (23 L. R. A. 181); Popa v. Northern Ins.

A., 155 Ill. App. 225.
So we are of the opinion that the insurer, under the facts stated in the second question, waived proofs of loss, ánd that the second question should be answered in the affirmative.
