The pivotal issue concerns the interpretation to be given to provisions of a life insurance contract. Specifically, the issue is whether a clause in the contract prohibiting the insurer, after a certain period of time, from contesting the policy for any reason other than nonpayment of premiums is affected by the lapse and reinstatement of the policy. We hold that it is not and affirm the Court of Appeals.
On 19 April 1975, the defendant issued a life insurance policy to plaintiffs husband, Leotha Jim Chavis, in the face amount of $17,000 with the plaintiff named beneficiary. Premiums were to be paid on a monthly basis. The contract of insurance contained the following pertinent provisions:
The Contract — This policy and the application therefor, a copy of which is attached hereto and made a part hereof, constitute the entire contract. All statements made by the Insured or in his behalf in the application in the absence of fraud shall be deemed representations and not warranties and no statement shall avoid any payment under this policy or be used in defense of any claim hereunder unless it is contained in one of these instruments.
INCONTESTABILITY — After this policy shall have been in force during the lifetime of the Insured for two full years from the date hereof, it shall be incontestable except for non-payment of premium, and except as to the provisions, if any, granting total and permanent disability insurance, and the provisions, if any, granting additional insurance specifically against death by accidental means.
*261Reinstatement — If this policy shall lapse in consequence of default in payment of any premium it may be reinstated at any time within five years upon evidence of insurability satisfactory to the Company and the payment of the defaulted premiums with interest ....
On 19 April 1980, the policy lapsed due to nonpayment of premium by the insured. Under the reinstatement provision the insured was entitled to have the lapsed policy reinstated at any time within five years of the default upon a showing of insurability satisfactory to the company and payment of the defaulted premiums with interest. On 25 June 1980, Mr. Chavis completed and returned an application for reinstatement of the policy. On the application for reinstatement Mr. Chavis answered several questions including the following:
Have you or any person to be insured by this policy had any sickness or injury or been attended by any physician within the past 5 years, or since the issuance of the policy, if later? No
To the best of your knowledge and belief are all persons to be insured in good health? Yes
Mr. Chavis also signed a statement to the effect that all answers given by him on the application were true. The policy was subsequently reinstated upon the payment of the defaulted premiums and interest.
Mr. Chavis continued to make the monthly payments until 25 July 1981 when he died in a house fire. Plaintiff thereupon filed a claim for the proceeds of the policy. The company denied payments under the policy contending that certain statements made by Mr. Chavis in the application for reinstatement were fraudulent and material misrepresentations of fact. Specifically, the company asserted that the defendant had been untruthful when he stated on the application for reinstatement that he had not been ill or attended by a physicián within the past five years and that he was in good health.
The plaintiff initiated this action seeking payment of the proceeds with interest plus attorney fees and court costs. The de*262fendant filed its answer alleging that the insured’s misrepresentations rendered the reinstatement void and invalid. Both parties subsequently filed motions for summary judgment. The plaintiffs motion for summary judgment was denied 27 January 1984. The defendant’s motion for summary judgment was granted 11 May 1984. The Court of Appeals vacated summary judgment in favor of the defendant and remanded the case for entry of summary judgment in favor of the plaintiff ruling that the incontestability clause in the policy foreclosed the defendant from asserting the insured’s alleged misrepresentation in the application for reinstatement as a defense to payment of benefits under the policy.
It is well established that contracts for insurance are to be interpreted under the same rules of law as are applicable to other written contracts. E.g., Motor Co. v. Insurance Co., 233 N.C. 251, 63 S.E. 2d 538 (1951); Woodell v. Insurance Co., 214 N.C. 496, 199 S.E. 719 (1938); Crowell v. Insurance Co., 169 N.C. 35, 85 S.E. 37 (1915). One of the most fundamental principles of contract interpretation is that ambiguities are to be construed against the party who prepared the writing. E.g., O’Grady v. Bank, 296 N.C. 212, 250 S.E. 2d 587 (1978); Contracting Co. v. Ports Authority, 284 N.C. 732, 202 S.E. 2d 473 (1974); Electric Co. v. Insurance Co., 229 N.C. 518, 50 S.E. 2d 295 (1948); Hardy v. Ward, 150 N.C. 385, 64 S.E. 171 (1909). Therefore, in an insurance contract all ambiguous terms and provisions are construed against the insurer. E.g., Woods v. Insurance Co., 295 N.C. 500, 246 S.E. 2d 773 (1978); Trust Co. v. Insurance Co., 276 N.C. 348, 172 S.E. 2d 518 (1970); Jolley v. Insurance Co., 199 N.C. 269, 154 S.E. 400 (1930).
Consistent with these principles is the rule that a life insurance policy containing a provision that it shall be incontestable after a specified time cannot thereafter be contested by the insurer on any ground not excepted from the incontestability provision. Trust Co. v. Insurance Co., 173 N.C. 558, 92 S.E. 706 (1917). The incontestability clause contained in the policy in question explicitly states that after the policy had been in force for two years it could not be contested by the company except for nonpayment of premium and except as to the provisions, if any, granting total and permanent disability insurance or granting additional insurance for accidental death. It is clear that none of these exclusions to noncontestability are relevant here. It is undisputed that the insured paid the monthly premiums from the *263time of the policy’s reinstatement until his death. Also, the insurer is not contesting the provisions of a disability insurance policy. Finally, the reinstatement of the lapsed policy did not constitute the purchase of “additional” life insurance. Reinstatement of a life insurance policy means that the policy is put back into force and effect. 1A J. Appleman & J. Appleman, Insurance Law and Practice § 320, at 356 (1981). Reinstatement of a lapsed policy does not result in the issuance of new or additional insurance. Since the incontestability provision does not expressly permit the company to contest the policy on grounds of material misrepresentations by the insured beyond the two-year limit, ordinary rules of contract construction would preclude the company from asserting this defense.
The defendant, however, contends that this Court should adopt the rule that when a lapsed insurance policy is reinstated, the contestability period contained in the original policy is renewed as to misrepresentations in the reinstatement application. We acknowledge that this appears to be the majority view. See 1A J. Appleman & J. Appleman, Insurance Law and Practice § 320, at 356-58 (1981) (and cases cited therein). However, some jurisdictions have adopted the view that if the contestable period has run the insurer may not assert any defense barred by the incontestability clause, whether such defense arose out of the original contract or out of the application for reinstatement. See, e.g., Munn v. Robinson, 92 F. Supp. 60 (W.D. Ark. 1950); New York Life Insurance Co. v. Dandridge, 202 Ark. 112, 149 S.W. 2d 45 (1941); Burnham v. Bankers Life and Casualty Co., 24 Utah 2d 277, 470 P. 2d 261 (1970). These cases reason that the reinstatement creates no new contract, but merely revives the original contract to the same extent as if there had been no lapse. If the contestability period has run the company is precluded from asserting a nonreserved defense to the same extent as if no lapse had occurred.
We find this reasoning persuasive. Indeed, in Petty v. Insurance Co., 212 N.C. 157, 161, 193 S.E. 228, 231 (1937), the Court said:
“The reinstatement of the policy or contract of insurance did not have the effect of creating a new contract of insurance, dating from the time of the renewal. It had the effect only of *264continuing in force the original contract of insurance which would, under its terms, have terminated and become void if it had not been reinstated in the manner and within the time provided in the original contract.”
The defendant contends the holding in Petty compels a decision in its favor. In Petty a life insurance policy lapsed due to nonpayment of premiums. The insured subsequently applied for reinstatement of the policy. Under the policy the insured was required to sign a certificate of health in order to obtain reinstatement of the policy. In the certificate of health the defendant was required to answer whether he was in good health and whether he had been sick or required the services of a physician during the past year. He answered these questions “yes” and “no” respectively. The company thereupon reinstated the policy. The insured subsequently died and his beneficiary sought to collect the proceeds. The insurance company refused payment alleging that the insured made material misrepresentations concerning his health in the certificate of health. The jury found that the representation concerning whether he had been sick or required the services of a physician during the past year was untrue and returned a verdict in favor of the company. This Court affirmed, holding that the representation in the certificate of health was required as a condition precedent to reinstatement and that a truthful answer was required. Since the jury found the statement to have been false, the Court ruled that the policy was not in law reinstated. Defendant contends Petty is squarely on point and controls the outcome of this case. We disagree.
In Petty the Court noted the “representation in the certificate of health was required as a condition precedent to reinstatement.” Id. at 162, 193 S.E. at 231. Here there is no such requirement in the reinstatement provision. There were only two conditions precedent to reinstatement of this policy should it lapse: presentation of evidence of insurability satisfactory to the company and payment of the defaulted premiums with interest. It is undisputed that the latter condition precedent was fulfilled. The former condition was also met. Evidence was presented to the company concerning the defendant’s health (i.e., insurability). The company obviously found this evidence to be satisfactory since it subsequently reinstated the lapsed policy. Since both conditions precedent were met, the policy was reinstated in law.
*265 Petty did not involve, or at least did not consider the effect of, a two-year incontestability clause. Petty, as we have noted, recognized that reinstatement of a policy of life insurance does “not have the effect of creating a new contract of insurance, dating from the time of the” reinstatement. Id. at 161, 193 S.E. at 231. Rather, it has “the effect only of continuing in force the original contract of insurance.” Id. When, therefore, the instant policy was reinstated pursuant to the terms of the reinstatement clause, it is as if there had been no interruption in the policy’s other provisions including the incontestability clause. The company, pursuant to this clause, may not now, after the lapse of two years, contest the policy on any grounds other than those excepted from the provisions of the incontestability clause.
For the reason given, the decision of the Court of Appeals is
Affirmed.
