11.5 Coverage Problems (Reservation of Rights, Non-Waiver Agreements, Waiver & Estoppel) and Negotiation, Competitive Estimates, Mediation & Arbitration

Key Takeaways

  • A reservation of rights letter is a unilateral notice that the insurer is continuing to investigate while preserving its right to deny coverage later on stated grounds.
  • A non-waiver agreement is a bilateral agreement signed by the insured and insurer confirming that investigating or adjusting the claim does not waive policy defenses; the insured is not required to sign it.
  • Waiver is the voluntary relinquishment of a known right, while estoppel prevents a party from asserting a right when the other party reasonably relied on its conduct; neither generally creates coverage for a risk the policy excludes.
  • The Standard Fire Policy states that no provision is waived by the insurer's requirements or proceedings relating to appraisal or an examination under oath.
  • Appraisal decides only the amount of loss, while arbitration and litigation can resolve coverage; disputes a public adjuster starts against an insured must be filed and heard in New York under 11 NYCRR 25.12(b).

Coverage Problems: When the Insurer Is Not Sure

Sometimes an insurer must keep investigating a loss even though it has doubts about coverage, such as a late notice, a possible vacancy, a suspicious origin, or an exclusion that may apply. If it keeps adjusting without protecting itself, it risks waiving a defense or being estopped from asserting one. Two documents manage that risk.

DocumentNatureSigned byPractical effect
Reservation of rights (ROR) letterUnilateral noticeInsurer onlyTells the insured the insurer is investigating or paying undisputed items while reserving its right to deny on the grounds stated. A well-drafted ROR identifies the specific policy provisions and facts.
Non-waiver agreementBilateral contractInsured and insurerBoth agree that the insurer's investigation, adjustment, or appraisal activity does not waive policy defenses. The insured may decline to sign; the insurer then typically relies on an ROR.

PA guidance: read every ROR closely. Respond in writing to each ground, supply documents that resolve the issue, and keep every Regulation 64 deadline in view. An ROR does not suspend the insurer's duties to acknowledge, investigate, and decide within the regulation's time frames. Before advising a client to sign a non-waiver agreement, confirm that it is limited to the issues actually in question, and remember that a PA may not give legal advice (Ins. Law § 2108(o)). A client who needs a legal opinion on a complex agreement should consult an attorney.

Waiver and Estoppel

  • Waiver: the voluntary and intentional relinquishment of a known right. Example: an insurer that knows of a late-notice defense but keeps demanding documents and negotiating without reserving rights may be found to have waived it.
  • Estoppel: a party is prevented from asserting a right because the other party reasonably relied on its words or conduct to its detriment. Example: an adjuster tells an insured in writing that the proof-of-loss deadline has been extended, the insured relies on it, and the insurer later tries to deny for late filing.
  • Limit: under New York law, waiver and estoppel generally operate on conditions and forfeitures (notice, proof of loss, cooperation). They generally cannot create coverage for a risk the policy never covered or expressly excludes.
  • Built-in protection for insurers: the Standard Fire Policy states that no permission affecting the insurance exists, and no waiver of a provision is valid, unless it is in writing. It also states that no provision, stipulation, or forfeiture is waived by any requirement or proceeding relating to appraisal or to any examination provided for in the policy. Demanding an EUO or taking part in appraisal is therefore not, by itself, a waiver.

ArbitrationAn arbitrator or panelYes, if agreed (CPLR Article 75)Issues the parties submit, which can include coverageContractual or agreed arbitration
LitigationA courtYesCoverage, breach, and damagesWhen other methods fail; suit time limits apply

Negotiation and Competitive Estimates

Effective negotiation rests on a complete, documented scope (Section 10.3), clear citations to policy language, and a written record. When an insurer relies on a low contractor bid, the PA tests whether the bid covers the same scope: code items, matching, general contractor overhead and profit, permits, and debris. The PA may also obtain competitive estimates from qualified local contractors. A bid for a narrower scope is not a competitive estimate of the same work.

Mediation

A mediator helps the parties find a settlement but cannot impose one. Mediation is informal, confidential in most programs, and fast. After major catastrophes, regulators have at times established mediation programs for property claims. Any agreement reached should be put in writing with a release limited to what is paid.

Arbitration

Arbitration produces a binding award on the issues submitted and is governed in New York by CPLR Article 75. Unlike appraisal, arbitration can decide coverage if the parties agree to submit it. Courts give arbitration awards very limited review.

Disputes Between the Public Adjuster and the Insured

Regulation 10, § 25.12(b), requires that any mediation, arbitration, or litigation initiated by a public adjuster against an insured over a New York loss be filed and held in New York and be subject to New York law. A PA cannot force a New York homeowner into an out-of-state forum over a fee dispute.

Releases in Settlement

A release is the document that ends a dispute. Under Regulation 64 (§ 216.6(g)), an insurer may not require a release broader than the scope of the settlement. A mediated or negotiated settlement of the building claim should release only the building claim, preserving contents, additional living expense, and replacement-cost holdback where they remain open.
