Who Writes an Affidavit for a Home Insurance Claim?
You do, as the policyholder, usually with a notary present, sometimes with help from a public adjuster or attorney.

Who actually fills out the affidavit
You write it, in your own words, because it's your statement of what happened and what was lost. The insurer may send a form, such as a proof of loss, asking you to list the damaged items, their value, and the date and cause of loss. You fill it in, sign it, and a notary witnesses your signature. If a contractor or public adjuster is helping with your claim, they might help you put the list together, but the affidavit still needs to reflect what you're swearing is true, not their estimate. Some insurers ask for a sworn statement in proof of loss as a condition of paying the claim, so check your policy or the letter you received for the deadline and the exact form required.
Your policy sets the deadline, not the adjuster
Most policies give you a set number of days to submit a sworn proof of loss, and missing it can cost you the claim. Comparing coverage now means knowing exactly what your policy requires before that clock runs out.
What happens if the numbers in the affidavit are wrong
An affidavit is a sworn statement, so an honest mistake is different from a false one. If you listed an item's value from memory and later find the receipt shows a different number, tell your insurer and correct it in writing. Insurers expect estimates to firm up as you gather documentation. What creates real trouble is signing a number you know is inflated, or leaving out damage you knew about when you swore the statement was complete.
Insurers can and do investigate sworn statements more closely than a casual claim form. If the value you swore to doesn't match receipts, photos, or a contractor's estimate, the insurer may ask you to amend the affidavit before paying anything. A sworn statement that turns out to be materially false can be used to deny the entire claim, not just the disputed item. Misrepresentation on a proof of loss is grounds for denial under most policies.
If you're unsure what an item is worth, say so. Use a range or note that the figure is an estimate pending appraisal. A sworn statement can still include your best good-faith number, as long as you're not claiming certainty you don't have. Keep copies of receipts, photos, and any contractor estimates you used to arrive at your figures, so you can show how you got there if the insurer asks.
If a public adjuster or contractor helped prepare your list, review every figure yourself before you sign. You are the one swearing to it, not them, and you're the one who answers for it later if a number turns out to be wrong. When in doubt about a specific value, it's reasonable to ask the insurer in writing whether they want a professional appraisal before you finalize the affidavit, rather than guess and swear to a number you might need to walk back.
What if you need to amend the affidavit after you've signed it
Sometimes you sign the proof of loss, mail it in, and only afterward find the contractor's estimate or a receipt that changes a number you swore to. This happens often enough that insurers have a standard way to handle it. You send a written amendment, sometimes called a supplemental proof of loss, that corrects the specific figure and explains why. You don't need to start over or withdraw the whole affidavit to fix one line item.
Put the amendment in writing even if you've already told the adjuster by phone. A phone call doesn't create a record, and a sworn statement should be corrected with the same formality it was made. State plainly what the original figure was, what the corrected figure is, and what new information caused the change, such as a contractor's estimate that came in after you signed. Attach the documentation. You generally don't need a new notary visit unless your insurer's form requires a fresh signature.
There's no fixed number of times you can amend a proof of loss, but each amendment should reflect genuinely new information, not a pattern of guessing low or high and correcting later. If you find yourself amending the same items repeatedly, that's worth a conversation with the adjuster about whether an independent appraisal would settle the value instead of more rounds of sworn estimates.
If your claim involves ongoing damage, like mold that's still spreading or a structure that's still being assessed for a full collapse, ask the insurer whether they want an initial proof of loss with a follow-up once the scope is final, or whether they'd rather wait for complete numbers. Some insurers accept a preliminary sworn statement that notes the damage is still being evaluated, which can protect your deadline without forcing you to guess at a final number. Get that agreement in writing too, since a deadline extension promised verbally is hard to prove later if the claim is disputed.
Before you sign anything
Find the proof of loss deadline in your policy or claim letter, and check every figure against a receipt, photo, or contractor estimate before you swear to it.
