How Long Do I Have to File a Proof of Loss in New York?
Under New York Insurance Law § 3407, failing to furnish a proof of loss does not invalidate or reduce your claim unless the insurer first gives you written notice, after the loss, that it wants proofs of loss on a suitable blank form. If you furnish proofs of loss within 60 days after receiving that notice and form — or within any longer period the notice allows — you are deemed to have complied with your policy's proof of loss deadline. Giving you the notice and form is not an admission of liability or a waiver of any policy condition.
Key Points
- The 60-day clock starts when the insurer sends written notice plus a blank proof of loss form, not at the date of loss.
- No written demand and form means a missed policy proof of loss deadline generally cannot be used to defeat your claim.
- The insurer can allow more than 60 days in the notice, but not less than the statute's protection.
- On a fire loss, immediate written notice to any licensed agent of the insurer in New York, with enough particulars to identify you and the property, is sufficient compliance.
- Federal flood claims under the NFIP have their own, stricter sworn proof of loss requirements — do not assume this section governs them.
What a proof of loss actually is
A proof of loss is a sworn statement of your claim: the date and cause of loss, the property involved, the amounts you are claiming, other insurance, and your interest in the property. It is the document that starts the insurer's decision clock under 11 NYCRR § 216.6 — 15 business days to accept or reject a properly executed proof of loss and all requested items.
Because it is sworn and because it frames the numbers, a rushed or lowball proof of loss can cap a claim before the full scope is even known. Hidden damage, code upgrades, contents, and loss of use frequently surface after the first submission.
The trap to avoid
Two mistakes cause most proof of loss problems on Long Island claims. The first is ignoring the form when it arrives — the 60-day clock in § 3407 is real once written notice and a blank form are given. The second is signing a figure that only reflects what has been found so far.
The safer path is to submit within the deadline, state the amounts supported by documentation, and preserve the right to supplement as additional damage is identified. If you need more time, ask in writing before the deadline passes.
