How do I dispute a rejected third-party motor insurance claim in India?

Motor insurance in India bundles two very different protections, and the dispute route depends on which one is involved:

(1) Third-party (TP) liability cover:
(a) Mandatory for every vehicle on an Indian road under Section 146, Motor Vehicles Act, 1988 — driving without it is a criminal offence;
(b) Pays for death, injury, or property damage caused by your vehicle to someone else — not for your own vehicle;
(c) Liability for death or injury is unlimited in principle; premiums are standardised and fixed by IRDAI every year, not set by the insurer;
(d) The injured third party (or their legal heirs) is the one who ultimately gets paid — not you, the policyholder;

(2) Own-damage (OD) cover:
(a) Optional, pays for repair or replacement of your own vehicle after an accident, theft, fire, or natural calamity;
(b) You are both the policyholder and the beneficiary, so a dispute here is a straightforward policyholder-vs-insurer grievance;

(3) Why this matters for disputing a rejection: when an insurer 'rejects' a third-party claim, it usually means it is refusing to admit liability on your behalf towards the victim, or contesting the extent of liability — this dispute is typically fought out before the Motor Accident Claims Tribunal, not resolved by an internal grievance letter the way an OD rejection often can be. See how vehicle insurance claims work generally for the full OD claim process.

Insurers typically raise one or more of these grounds when resisting third-party liability:

(1) Driver had no valid licence for that class of vehicle at the time of the accident, or was driving on a learner's licence without a qualified supervisor — the single most litigated rejection ground;
(2) Policy had lapsed or was not in force on the date of the accident;
(3) Breach of permit or route conditions — e.g., a goods vehicle used outside its permitted route, or a private vehicle used commercially;
(4) Vehicle used for a purpose outside the policy — e.g., a vehicle insured for private use found to be plying as a cab;
(5) Fraud or fabricated/exaggerated claim, or a staged accident;
(6) Driving under the influence of alcohol or drugs at the time of the accident;
(7) Late or no intimation of the accident to the insurer;

Important nuance specific to third-party claims: even where the insurer proves one of grounds (1)-(4) above, Indian courts have repeatedly applied the 'pay and recover' principle — the insurer is first directed to pay the injured third party or their legal heirs in full, and is only afterwards permitted to recover that amount from the vehicle owner or driver who breached the policy condition. So a 'rejection' on these grounds does not leave an injured third party without a remedy; it shifts the eventual financial burden to the insured, not the victim. This principle has been reaffirmed by the Supreme Court in multiple motor accident appeals, including cases involving invalid licences and permit breaches — confirm the latest position with a lawyer or the MACT registry for your specific facts, since courts apply it fact-by-fact.

Before escalating externally, exhaust the insurer's own grievance mechanism — tribunals and the Ombudsman generally expect this first:

1. Write to the insurer's Grievance Redressal Officer / Nodal Officer (named on the policy document and the insurer's website), stating the claim number, the rejection letter's grounds, and why you dispute them.
2. Ask for the rejection reason in writing if it was only communicated verbally — you need this document for every later stage.
3. Most insurers commit to responding within 15 working days, though you should verify the current timeline stated in your policy's grievance redressal clause or the insurer's own citizen's charter, since this can vary.
4. If the vehicle owner (not just the injured third party) is the one disputing repudiation of their indemnity, also check whether the policy's internal ombudsman clause (introduced for larger insurers) applies before going external.

(1) Insurance Ombudsman:
(a) A free, quasi-judicial forum under the Insurance Ombudsman Rules, intended for disputes between a policyholder and their own insurer — typically own-damage repudiation, delay in settlement, or disputes over the quantum of an own-damage payout;
(b) Complaints must generally be filed after the insurer's final response or after a stated waiting period, and within a limitation window from that response — confirm the current limitation period and pecuniary (monetary) ceiling directly with your regional Ombudsman office or cioins.co.in, as both have been revised in recent years and sources are not always consistent;
(c) A pure third-party liability dispute — where the injured party or claimant is not the insurer's own policyholder — is generally outside the Ombudsman's remit and is directed instead to MACT; the Ombudsman route is more relevant where you, the policyholder, are disputing how the insurer handled your defence or indemnity;

(2) IRDAI:
(a) File a complaint on the Bima Bharosa portal (bimabharosa.irdai.gov.in) or call the IRDAI Grievance Call Centre, generally after giving the insurer a chance to respond first;
(b) IRDAI does not adjudicate individual compensation disputes itself, but it can direct the insurer to follow proper claims-handling procedure and escalate unresolved service failures;
(c) Use this route for process failures — unreasonable delay, failure to respond, failure to depute a surveyor — rather than as a substitute for a MACT claim on liability itself.

Where the insurer disputes liability for death or injury to a third party, the claim is decided by the MACT constituted under Section 165, Motor Vehicles Act, 1988:

1. Who can file: the injured person, or the legal heirs/dependants in a fatal accident, under Section 166.
2. What to file: the prescribed claim petition, FIR copy, medical records or post-mortem/death certificate, income and age proof of the victim, and details of the vehicle and insurer.
3. Insurer is made a party: the vehicle owner's insurer is impleaded as a respondent and can contest liability before the Tribunal — this is where the insurer's rejection grounds (invalid licence, permit breach, etc.) actually get tested, with the 'pay and recover' principle applied if the Tribunal finds a breach but still orders the insurer to pay the victim first.
4. Limitation period: Indian law on this has changed more than once — a six-month limitation from the date of the accident was reinserted into Section 166(3) by the 2019 amendment, with that specific provision notified for enforcement from 1 April 2022; this reinstated limitation has itself been challenged in court. Do not rely on a fixed number from this page — confirm the limitation position currently in force, and any condonation-of-delay possibility, with the Tribunal registry or a lawyer before you file, and file as early as possible regardless.
5. No-fault / structured compensation: Section 164 provides a no-fault interim compensation scheme for death and permanent disability, payable without having to prove negligence, while the main Section 166 claim for full compensation proceeds separately.
6. Hit-and-run cases, where the vehicle or insurer cannot be identified, are compensated from the Solatium Fund rather than through a named insurer's third-party cover — see hit-and-run cases and compensation.
7. Many MACT claims are also settled through Lok Adalats, which offer a faster, cooperative settlement before full-length litigation.
