Insurance Grievance Letter Template India — Write to Your Insurer's GRO

A formal grievance letter to your insurance company's Grievance Redressal Officer (GRO) is not just good practice — it is a mandatory prerequisite before you can file with IRDAI IGMS or escalate to the Insurance Ombudsman. Without this step on record, the Ombudsman will not accept your complaint. This guide provides a template you can adapt for any insurance dispute, along with guidance on what each section must contain.

When to write to the GRO

Write to the GRO as soon as your claim has been rejected or you have received a final decision you disagree with. Do not wait. The Insurance Ombudsman requires complaints to be filed within one yearof the insurer's final rejection. Starting the GRO process promptly preserves your Ombudsman option.

Every insurer licensed by IRDAI must have a designated GRO. Their contact details must be printed on your policy document and published on the insurer's website. Most insurers also have an online complaints portal — using this creates a timestamp record of your submission.

The grievance letter template

Copy and adapt the following template. Replace all text in [brackets] with your specific details.

To, The Grievance Redressal Officer [Full name of insurance company] [Company address — found on your policy document] By email: [GRO email address from the insurer's website] By post / courier: [address above] Date: [Date] Subject: Formal Grievance — Wrongful Rejection of Claim No. [CLAIM NUMBER] Policy No. [POLICY NUMBER] | Insured: [YOUR FULL NAME] Dear Sir/Madam, I write to formally grieve the rejection of my insurance claim under the above-referenced policy. 1. BACKGROUND I hold [type of insurance] policy No. [POLICY NUMBER] issued by [insurer name], with a sum insured of ₹[AMOUNT]. The policy has been continuously in force since [ORIGINAL INCEPTION DATE] and is currently valid until [EXPIRY DATE]. On [DATE OF HOSPITALISATION / INCIDENT], I [briefly describe what happened — hospitalised for X / vehicle damaged / insured died]. I filed claim No. [CLAIM NUMBER] on [DATE CLAIM FILED]. 2. THE REJECTION By letter / email dated [REJECTION DATE], [insurer name] rejected my claim on the stated ground that: "[QUOTE THE REJECTION REASON EXACTLY AS STATED]." 3. WHY THIS REJECTION IS INVALID [Choose and adapt the applicable argument:] For pre-existing condition rejections: The pre-existing condition exclusion does not apply because [choose one or more]: (a) The condition treated was not caused by the alleged pre-existing condition — the pre-existing condition must be the direct and proximate cause of treatment, not merely present in my medical history. (b) I have held this policy for [X] years, and the [X]-year PED waiting period has been fully served. (c) I was not aware of the alleged condition at the time of the proposal — it was first diagnosed during the current hospitalisation. For non-disclosure rejections: The non-disclosure ground fails because [insurer name] has not established all three required elements: (a) That the statement in the proposal was false; (b) That it was material to the underwriting decision; and (c) That it was made with fraudulent intent to deceive. [Specify which elements are not established and why.] For cashless / delay rejections: The denial of cashless pre-authorisation was invalid because [insurer name] / the TPA failed to respond within the 1-hour period mandated by IRDAI regulations. The pre-authorisation request was submitted at [TIME] and the response (if any) was received at [TIME] — a gap of [X] hours/minutes. For late intimation rejections: The rejection on grounds of late intimation is invalid. IRDAI regulations and Supreme Court precedent require the insurer to demonstrate actual prejudice caused by the delay — not merely that the delay occurred. No such prejudice exists in this case because [explain]. 4. APPLICABLE REGULATION [Choose the applicable regulation:] - IRDAI Health Insurance Regulations, 2016 (as amended) - Section 45, Insurance Act 1938 (for life insurance after 3 years) - IRDAI Motor Insurance Guidelines - IRDAI Travel Insurance Guidelines 5. RELIEF SOUGHT I respectfully request that you: (a) Review the rejection in light of the above; (b) Approve and settle the claim in full amounting to ₹[CLAIMED AMOUNT]; or (c) Provide a written, reasoned response within 15 working days as required under IRDAI Grievance Redressal Guidelines. I attach in support: - Rejection letter dated [DATE] - [List supporting documents: hospital bills, discharge summary, medical reports, policy document, etc.] If this grievance is not resolved within 30 days, I intend to file a complaint on IRDAI IGMS (igms.irda.gov.in) and escalate to the Insurance Ombudsman for [your region]. Yours faithfully, [FULL NAME] [ADDRESS] [MOBILE NUMBER] [EMAIL ADDRESS] [DATE]

What makes a grievance letter effective

Cite the specific rejection ground exactly

Quote the rejection reason from the insurer's letter word for word. If the insurer later argues a different ground at the Ombudsman, you can point to the inconsistency between the rejection letter and their defence.

Name the applicable regulation

A letter that cites the specific IRDAI regulation — not just “my rights” — signals that you understand the legal framework. Insurers handle hundreds of complaints; a legally grounded letter is taken more seriously than a general protest.

Request a written response within 15 days

IRDAI requires the GRO to respond within 15 working days. Explicitly requesting this response on this timeline creates a traceable record. If they miss it, you have documented non-compliance.

State your escalation intention

Mentioning IRDAI IGMS and the Ombudsman in your letter signals that you know the full process. This is not a threat — it is a statement of fact about what the process requires. It also sets expectations about what happens if the GRO does not resolve the dispute.

Send by email and keep records

Email creates a timestamped record. If the insurer has an online complaints portal, use it — the submission timestamp is automatically recorded. Print or save a copy of the submission confirmation. You will need this evidence at the Ombudsman stage.

After sending the letter

  • 15 working days: The insurer must respond. If they respond and resolve the dispute, you are done.
  • 30 days: If unresolved after 30 days (or if the GRO response is unsatisfactory), file on IRDAI IGMS at igms.irda.gov.in.
  • Ombudsman: If IGMS does not resolve it, file with the Insurance Ombudsman for your region. The Ombudsman process is free, binding on the insurer, and covers claims up to ₹30 lakh.
