The policy issued by Nationwide to Mrs. King contained all provisions of an owner’s policy of liability insurance required by G.S. 20-279.21 as proof of the financial responsibility required by G.S. 20-309 et seq. The distinction between an owner’s policy of liability insurance and an operator’s policy of liability insurance, the required provisions of each being set forth in G.S. 20-279.21, is pointed out in Howell v. Indemnity Co., 237 N.C. 227, 74 S.E. 2d 610, and Lofquist v. Insurance Co., 263 N.C. 615, 140 S.E. 2d 12.
In Woodruff v. Insurance Co., 260 N.C. 723, 133 S.E. 2d 704, the plaintiff had obtained judgment against the party to whom the defendant had issued an owner’s assigned risk policy. Defendant based its defense on its policyholder’s failure to give it notice of the accident as required by the policy. This Court, in opinion by Denny, C.J., said: “Our Financial Responsibility Act does not require an owner’s assigned risk policy to cover any liability except that growing out of the operation of the motor vehicle described in the policy. *499Consequently, the coverage in the policy issued by the defendant to Holbrook with respect to the use of other automobiles, was in addition to the coverage required by our Motor Vehicle Safety and Financial Responsibility Act. Therefore, with respect to such coverage, the policy makes the giving of notice a condition precedent to insurer’s liability.” In this connection, see also Howell v. Indemnity Co., supra.
G.S. 20-279.21 (g) provides: “Any policy which grants the coverage required for a motor vehicle liability policy may also grant any lawful coverage in excess of or in addition to the coverage specified for a motor vehicle liability policy and such excess or additional coverage shall not be subject to the provisions of this article. With respect to a policy which grants such excess or additional coverage the term ‘motor vehicle liability policy’ shall apply only to that part of the coverage which is required by this section.”
Since Nationwide’s liability, if any, is based on “coverage in excess of or in addition to the coverage specified for a motor vehicle liability policy,” decision herein is governed by Muncie v. Insurance Co., 253 N.C. 74, 116 S.E. 2d 474, rather than by Swain v. Insurance Co., 253 N.C. 120, 116 S.E. 2d 482.
This Court has held binding and enforceable provisions requiring that an insured give notice of an accident, Muncie v. Insurance Co., supra, and Woodruff v. Insurance Co., supra, and requiring the insured’s cooperation in defense of any action against him, Henderson v. Insurance Co., 254 N.C. 329, 118 S.E. 2d 885. Moreover, the cited cases establish that compliance with such policy provisions is a condition precedent to recovery, with the burden of proof on the insured to show compliance, where the policy, as in this case, provides, “No action shall lie against the Company unless, as a condition precedent thereto, the Insured shall have fully complied with all the terms of this policy,” or words of like import. Moreover, with reference to an owner’s policy of insurance, unless the action be based on policy provisions required by G.S. 20-279.21, as in Swain v. Insurance Co., supra, an injured party who obtains a judgment against the insured has no greater rights against the insurer than those of the insured. Muncie v. Insurance Co., supra, and cases cited; Woodruff v. Insurance Co., supra.
While no decision of this Court involving a policy provision, “If claim is made or suit is brought against the Insured, he shall immediately forward to the Company every demand, notice, summons or other process received by him or his representative,” has come to our attention, decisions in other jurisdictions hold this is an unambiguous, reasonable and valid stipulation, and that, unless the insured or his judgment creditor can show compliance by the insured *500with this policy requirement, the insurer is relieved of liability.

As stated by Frankum, J., in Employees Assurance Society v. Bush, 123 S.E. 2d 908 (Ga.): “In order to hold the insurer liable for damages under the policy, provisions of the policy place upon the insured the duty of complying with two conditions: first, to notify the company of the accident, and second, to forward to the insurer every demand, notice, summons, or process received by him or his representative. The purpose is to inform the insurer of the occurrence of the two events.” In Potter v. Great American Indemnity Co. of N. Y., supra, Wilkins, J., said: “It is none the less a breach notwithstanding the fact that the company received prompt written notice of the accident under another condition of the policy. These were separate and distinct undertakings by the insured. (Citation). It is not for the plaintiff to assert that the company may not have been prejudiced by failure to receive the summons ‘immediately' as stipulated.”
“An automobile liability insurer may, by waiver or estoppel, lose its right to defeat a recovery under a liability policy because of the insured’s failure to comply with the policy provision as to the forwarding of suit papers.” 7 Am. Jur. 2d, Automobile Insurance § 188; 45 C.J.S., Insurance § 1058; Annotation, 18 A.L.R. 2d 443, 487. The subject of waiver will be discussed later with specific reference to the facts in evidence.
Defendant excepted to and assigns as error the denial of its motion at the conclusion of all the evidence for judgment of nonsuit. See G.S. 1-183; Murray v. Wyatt, 245 N.C. 123, 128, 95 S.E. 2d 541. Decision with reference thereto requires consideration of the evidence in the light of the foregoing legal principles.
Plaintiff’s evidence, apart from the testimony of Ruby B. King, judgment debtor and Nationwide’s policyholder, and of Sylvia P. Edwards, consists of the testimony, on adverse examination prior to trial, of Stanley J. Wiemer, H. F. Snevel and William J. Martin; *501and of the testimony, on adverse examination at trial, of Robert L. Triplett, James Edward Harrington and E. J. Sealey.
The testimony of Mrs. Edwards, a court reporter, related solely to features of the trial of the prior action, including identification of the attorneys who appeared therein.
The adverse examination of Wiemer, Resident Vice President of Nationwide, was exploratory in nature and resulted in no pertinent discovery. Hence, no further reference will be made to Wie-mer’s testimony. The testimony elicited on the other adverse examinations is summarized, except when quoted, as set out below.
After notice of the collision of February 6, 1964, investigation thereof was assigned by Nationwide to Sealey, its District Office Manager in Wilmington. On or about February 13, 1964, Sealey assigned the investigation to M. E. Gooch and Associates (Gooch), independent claims adjusters of Wilmington. Triplett, Claims Manager for Gooch, assigned the field investigation to Harrington, an employee of Gooch. Statements were obtained (recorded in Harrington’s phraseology and handwriting) from Florence Jean Clem-mons, Myrtle Clemmons Strickland, Eulene Lee, Rufus Vonnie King, Ruby Blanton King and Jimmy Lee Maggard.
Triplett’s initial report dated February 25, 1964, advised Nationwide that Mrs. Clemmons “had sustained very minor injuries” and, based on Gooch’s evaluation of the claim, stated: “Her injuries are such that settlement certainly can be made within the initial or primary coverage and we should not be involved, and therefore we are not suggesting a BI reserve.” (Note: “BI” is the abbreviation for Bodily Injury.)
Gooch’s said report also advised Nationwide that Mr. Ray Walton was representing Mrs. Clemmons. The report contained the following: “Your insured and her family, which were the occupants of the insured unit at the time, are represented by Attorney Bunn Frink of Southport, North Carolina.”
Gooch closed its investigation on February 28, 1964. Thereafter, on March 2, 1964, Triplett sent to Nationwide a hospital bill relating to Mrs. King’s injuries, and on March 20, 1964, a medical report relating to Mrs. Strickland’s injuries. The Gooch reports were filed with Martin, a claims examiner for Nationwide in Raleigh. Until a suit is instituted, a “claims examiner” or “division claims manager” has supervision of claims.
Snevel was an assistant claims attorney. On the day of the trial of the plaintiff’s action against Mrs. King and Mrs. Lee, and a short time prior to the commencement thereof, Mr. Frink advised the Raleigh office of Nationwide of the pending action and of the imminent trial thereof. Prior to receiving information of Mr. Frink’s *502said message, Snevel had heard nothing of the suit or of the “open claim,” the file with reference to the “open claim” being under the supervision of (claims examiner) Martin.
According to Snevel, Nationwide had no regularly retained counsel at Southport. It retained counsel to defend actions against its insureds on a case by case basis. Sometimes it had “hired”' Mr. Frink, sometimes Mr. Smith (counsel for Nationwide in the present action) and sometimes other counsel to represent its insureds in Brunswick County.
Evidence admitted over defendant’s objection tended to show Mr. Joshua S. James, a Wilmington attorney, and Mr. Frink, a Southport attorney, had represented and defended Mrs. King and Mrs. Lee at August 1964 Session at the trial of plaintiff’s said prior action. Questions were asked, and exhibits were offered and later stricken, the general purport of which was to leave the impression that Mr. Frink or Mr. James or both were retained by Nationwide to represent Mrs. King in said action and represented her pursuant to employment by Nationwide. However, no legitimate inference to that effect may be drawn from any facts in evidence. Moreover, there is no allegation that such was the case and no suggestion in the court’s charge that plaintiff sought to recover herein on that theory.
The other evidence consisted of the testimony of Mrs. King, a witness for plaintiff, and of the testimony of Braxton L. Prevatte, defendant’s agent at Whiteville, North Carolina, from whom Mrs. King purchased the Nationwide policy. Prevatte was the only witness offered by defendant. Both testified that Mrs. King reported the accident to Prevatte a few days after its occurrence on February 6, 1964. In other respects, their testimony was in conflict.
Prevatte testified in substance: He advised Mrs. King, when she called him and reported the accident, that he would notify the Claims Department of Nationwide and they would take care of it. Thereupon, he communicated the information Mrs. King had given him to Nationwide. Prevatte recalled no further conversation with Mrs. King concerning the matter.
Since contradictions and discrepancies must be resolved in favor of plaintiff, we must turn to and accept as true the testimony of Mrs. King. Her testimony, summarized except when quoted, was as follows: Shortly after her original report of the accident, she telephoned Prevatte again. In this conversation, she advised him she had been tried in Recorder’s Court for a traffic violation and had been found not guilty. This (second) telephone conversation occurred before Mrs. Clemmons started her suit. She called Pre-vatte a third time, when she was “sued”' — when she “got the paper.”
*503Testimony of Mrs. King with reference to this (third and last) telephone conversation, which bears directly on the crucial question for decision, was as follows: “I called him (Prevatte) on that occasion at his office in Whiteville. Exactly what I told him when I called him was that I had been sued. He did not say anything to me. I just told him that. He didn’t say anything. Yes, sir, I told him who I was when he answered the phone. I said this is Mrs. Ruby King, I have been sued by Jean Clemmons, that is right. No, sir, he did not make any comment to me at all. I then hung up. Yes, sir, I knew Mr. Prevatte pretty well. As to whether or not I know of my own knowledge that I was actually talking to Mr. Pre-vatte, I say it sounded like his voice and I have been to his office several times. I.don’t remember approximately how long it was after I got the suit papers that I called and talked to someone that sounded like Mr. Prevatte. The best estimate I could give you is it was within a week. I took the suit papers to my lawyer. That was Mr. Bunn Frink.” Again: “I never did send the suit papers to my own insurance company, Nationwide. I have the original policy somewhere at the house.” Again: “After I gave the suit papers to Mr. Frink, I did not call Mr. Prevatte any more after that. I did not call any person connected with Nationwide Insurance Company after I gave the suit papers to Mr. Frink or tell them I had been sued or had any papers, no, sir.”
Nationwide makes no contention it did not receive timely notice of the accident. On the contrary, it admits it received such notice and caused an investigation to be made. It contends such investigation indicated Mrs. King’s liability, if any, for Mrs. Clemmons’ injuries, was within the coverage provided by Dixie’s policy on Mrs. Lee’s car. Its asserted ground of defense is that Mrs. King did not comply with the pleaded policy provision. ,
All the evidence, including the testimony of Mrs. King, tends to show Mrs. King did not “forward to the Company every demand, notice, summons or other process received by (her) or (her) representative,” in plaintiff’s said prior action. Indeed, her testimony is that she delivered the papers that were served on her in plaintiff’s prior action, presumably the summons and complaint, to her own attorney, Mr. Frink. Hence, the court correctly directed the jury to answer the first issue, “No.” Nothing else appearing, this negative answer to the first issue defeats plaintiff’s asserted right to recover herein.
Decision as to nonsuit depends upon whether plaintiff’s allegations and evidence with reference to waiver were sufficient to withstand defendant’s motion. Plaintiff alleged the requirement that Mrs. King “forward to the Company every demand, notice, sum*504mons or other process received by (her) or (her) representative” was waived by defendant “by failing and refusing to instruct the defendant (i.e., Mrs. King) to whom or to what address said papers should be delivered.” The evidence must be considered in the context of plaintiff’s allegations in passing upon whether it was sufficient for submission to the jury. Faison v. Trucking Co., 266 N.C. 383, 146 S.E. 2d 450.
It is noted that plaintiff relies primarily on her (according to her testimony) third telephone conversation with Prevatte. There is no evidence Prevatte refused to answer any inquiry or that he failed to comply with any request or that he gave Mrs. King any misleading directions or instructions. Mrs. King’s testimony indicated (somewhat uncertainly) that she knew she was talking to Prevatte because “it sounded like his voice.” Her testimony, considered in the light most favorable to plaintiff, is to the effect she advised Prevatte she had been sued and that suit papers had been served on her. Notwithstanding, she insisted that “he (Prevatte) did not make any comment to (her) at all.”
In Hospital v. Stancil, 263 N.C. 630, 139 S.E. 2d 901, distinctions between estoppel and waiver are pointed out by Sharp, J. Compare Boyle Road & Bridge Co. v. American E. Ins. Co., supra. Suffice to say, plaintiff’s allegations relate to waiver, not to estoppel.
Ordinarily, waiver is defined as a voluntary and intentional relinquishment of a known right. In Hospital v. Stancil, supra, waiver is defined as “the intentional surrender of a known right or privilege, which surrender modifies other existing rights or privileges or varies the terms of a contract.” In Fetner v. Granite Works, 251 N.C. 296, 302, 111 S.E. 2d 324, Moore, J., in accord with 56 Am. Jur., Waiver § 12, stated: “The essential elements of a waiver are: (1) the existence, at the time of the alleged waiver, of a right, advantage or benefit; (2) the knowledge, actual or constructive, of the existence thereof; and (3) an intention to relinquish such right, advantage or benefit.”
In Boyle Road Ac Bridge Co. v. American E. Ins. Co., supra, with reference to a similar policy provision, Fishburne, J., stated: “(I)n our opinion mere knowledge by the Insurance Company of the fact that process has been served upon the insured does not of itself amount to a waiver or an estoppel. There must exist, in addition to such knowledge, where the papers have not been forwarded to the Insurance Company as provided in the contract, some positive act upon which, in connection with the knowledge, a waiver may be predicated. And this positive act must be known to the insured.” In accord: Nevil v. Wahl, supra; De Vigil v. General Accident Fire & Life Assurance Co., supra.
*505Consideration of the evidence in the light most favorable to plaintiff impels the conclusion that Prevatte’s silence, when advised that Mrs. King had been sued, is insufficient to support a finding that Nationwide thereby knowingly and intentionally waived its rights under the contract provision pleaded by defendant. Defendant’s motion for judgment of nonsuit should have been granted. Accordingly, the judgment of the court below is reversed.
Reversed.
