Union Standard Insurance Company appeals a trial court judgment declaring that Gene Kimbrell is indemnified under a garage operations insurance policy issued to his corporation, Gene Kimbrell’s Body Shop, Inc. We reverse based on Mr. Kim-brell’s failure timely to notify Union Standard of the underlying lawsuit.
I.
Mr. Kimbrell was involved in a motor vehicle accident in January, 1997. According to trial testimony, two or three months later he discussed the accident with an individual at First Arkansas Insurance, where he had purchased the Union Standard policy. In May, 1997, Steven Roberts filed a state lawsuit for injuries arising out of the accident, and Mr. Kimbrell filed an answer the same month. In October, the state court granted partial summary judgment to Mr. Roberts, holding that Mr. Kimbrell was hable for the accident. Damages issues, however, still had to be tried. Exactly two months later, Mr. Kimbrell’s attorney sent to First Arkansas a copy of thе state court complaint and a demand that Union Standard participate in Mr. Kimbrell’s defense. First Arkansas forwarded the documents to Union Standard.
In a subsequent letter to Mr. Kimbrell’s attorney, Union Standard denied coverage based on policy provisions unrelated to notice and further stated that by relying on these provisions it “[did] not intend to waive any other provisions of the policy.” Mr. Kimbrell then filed a state declaratory judgment action, which was removed to federal court. Union Standard’s answer to the cоmplaint included an allegation that coverage was precluded because Mr. Kim-brell failed to give notice of the claim. The trial court, prior to entering a judgment holding that the Union Standard policy provided coverage for the accident, denied Union Standard’s summary judgment motions, one of which contended that Mr. Kimbrell failed tо comply with the policy’s notice provisions. On appeal, Union Standard again raises the issue of notice.
II.
We agree with the parties that Arkansas law apрlies in this diversity action. In order for timely notice to be a condition precedent to coverage, the insurance policy must use language expressly to that еffect or language that necessarily implies that the provision is a condition precedent.
See Hope Spoke Co. v. Maryland Casualty Co.,
Union Standard contends that Mr. Kimbrell breached section 2 of the “Loss Cоnditions,” which sets forth the following “Duties in the Event of Accident, Claim, Suit or Loss”:
In the event of “accident,” claim, “suit” or “loss,” you must give [Union Standard] or our authorized representative prompt notice of the “accident” or “loss.” Include: (1) How, when and where the “accident” or “loss” occurred; (2) The “insured’s” name and address; and (3) To the extent possiblе, the names and addresses of any injured persons and witnesses.... Additionally, you and any other involved “insured” must ... [immediately send [Union Standard] copies of any request, demand, order, nоtice, summons or legal *537 paper received concerning the claim or “suit.”
Section 3 of the “Loss Conditions” includes the following language:
No one may bring a legal action against [Union Standard] under this Coverage Form until: ... There hаs been full compliance with all the terms of this Coverage Form.
We conclude that the policy “conditions” stating that the insured must give prompt notice and immediately fоrward legal papers (notice provisions), combined with the requirement that no legal action may be brought without “full compliance with ... [the] Coverage Form,” establish by nеcessary implication that the notice provisions are conditions precedent to recovery.
See M.F.A. Mutual Insurance Co. v. Mullin,
Addressing another issue during the trial, Don Martin (the agеnt who sold the policy in question) testified that Mr. Kimbrell discussed the accident with a First Arkansas employee about two or three months after it occurred, and we note that оn a page of the policy entitled “Common Policy Declarations” Mr. Martin’s signature and “First Arkansas Insurance” appear on the signature line and above the words “Authоrized Representative.” Even assuming, however, that this discussion with the First Arkansas employee constitutes the required “prompt notice” of the “accident” to an “authorizеd representative,” the policy further compelled Mr. Kimbrell “[i]mmediately [to] send” to Union Standard the legal papers regarding Mr. Roberts’s lawsuit.
Although immediate notice dоes not necessarily mean instantaneous notice, it does mean notice “within a reasonable time under all the facts, circumstances, and conditions.”
See Maryland Casualty Co. v. Waggoner,
III.
The trial court concluded that Union Standard waived its right to assert the policy’s notice provisions by asserting other grounds for denying coverage. In so holding, the сourt relied on
Tri-State Insurance Co. v. Smith,
In
Tri-State,
however, unlike our case, the insured gave timely notice of the occurrence and оf a related lawsuit, and the insurer’s agent twice stated that the policy provided no coverage,
id.,
449 S.W.2d at
*538
700; the court thus held that the insurer did not have the right to require the insured to give notice when the injured party refiled the action after a nonsuit.
See id.,
We note that waiver and estoppel, although often used interchangeably in insurance law, are not synonymous,
see Bethell v. Bethell,
We alsо note that to establish a waiver (as opposed to an estoppel), Mr. Kimbrell has to show that Union Standard intentionaUy relinquished a known right.
See Bethell,
IV.
, Accordingly, we reverse the trial court and remand this case to that court for the entry of a judgment in favor of Union Standard consistent with this opinion.
