Proof of loss
A signed, sworn statement of what happened and what you are claiming, which most policies require within a set number of days.
Also called: sworn proof of loss, POL, sworn statement in proof of loss
A proof of loss is a written statement, signed under oath, in which you give the time and cause of the loss, who has an interest in the property, any other insurance that applies, and the amount you are claiming. It normally travels with support: repair estimates, a contents list, and receipts for additional living expenses.
Under the standard ISO homeowners form (HO 00 03), you must send a signed, sworn proof of loss within 60 days after the insurer asks for it. The clock runs from the request, not the date of the loss, though state law and an insurer's own form can change that. The standard federal flood policy works differently: it generally sets a 60-day deadline measured from the date of the loss, and FEMA has extended that period after some declared disasters.
Treat it as more than paperwork. The figure you swear to is the figure the insurer will hold you to, and a knowingly inflated number can void the claim. Missing the deadline, or filing an incomplete form, hands the insurer a reason to delay or deny. If you need more time, ask in writing and keep the reply. For the mechanics, read the proof of loss form and its deadlines and your duties under the policy.
