Who Can Do a Sworn Affidavit for a Home Insurance Claim?
Usually you, the policyholder, sign it before a notary, since you have firsthand knowledge of the loss.

Who actually signs it
The affidavit has to come from someone with firsthand knowledge of the loss, which is almost always you as the policyholder. If a co-owner or spouse also lives in the house, your insurer may want their signature too, especially if both names are on the policy.
What the notary checks
A notary isn't reading your claim for accuracy. They're confirming your identity and watching you sign, then they stamp it. Bring a government-issued ID. If you sign before seeing the notary, they'll usually make you sign again in front of them.
Why insurers ask for one
A sworn affidavit turns your claim into a legal statement. If anything in it turns out to be false, that can be used against you, which is why insurers lean on it for larger losses, suspected fraud cases, or when your account of events has changed.
Getting the wording wrong
Insurers often supply the affidavit form, and the wording matters. Don't sign anything that states a damage amount or cause you're not certain of. Read it fully before your notary appointment, and ask your insurer or adjuster to explain any line you don't understand.
A signed affidavit is not the end of the conversation
Signing one doesn't lock in the insurer's number. If the payout still falls short of what rebuilding or repairs actually cost, your policy and the market for coverage like it are worth checking.
What if you can't sign it yourself
Sometimes the policyholder isn't in a position to sign. Someone might be hospitalized, out of the country, or the loss involves a death, like a fire claim after a homeowner has died. In those cases, a person with legal authority can usually sign in their place. That means someone holding power of attorney, an executor named in a will, or a court-appointed guardian or conservator. The insurer will want to see the paperwork proving that authority before accepting the signature, so have it ready rather than waiting to be asked.
If the house is owned by a trust or an LLC, the trustee or an authorized member typically signs, not a tenant or property manager, even if that person handled the damage and dealt with contractors. Insurers want the affidavit from someone with a legal stake in the property, not just someone familiar with what happened. If you're not sure who that is on a jointly owned or recently inherited property, check with the insurer before the notary appointment, since sending the wrong signer back will just cost time.
A public adjuster or attorney helping with the claim cannot sign the affidavit in your place, even with a signed authorization letter. They can negotiate, gather documents, and talk to the insurer, but the sworn statement about the loss has to come from someone who actually witnessed or experienced it. If your adjuster suggests otherwise, that's worth a second look.
For married couples where only one name is on the policy, the named policyholder is usually enough, but insurers sometimes ask the spouse to sign as well if they also live in the house and have relevant knowledge, particularly for a theft or liability claim where both accounts matter. If you're unsure whether a second signature is needed, ask the adjuster directly rather than guessing, since an affidavit missing a required signature can delay payment by weeks while it's redone.
What happens if the affidavit has an error on it
Mistakes happen. You write the wrong date, misstate a dollar figure, or notice after signing that you left out a damaged item. An error on a signed affidavit isn't something you can cross out and initial. It's a sworn, notarized document. A correction usually means signing a new one in front of a notary again, not editing the old one.
Call the adjuster as soon as you catch the mistake, even a small one. A wrong date or a misspelled address might just need a short corrected affidavit. A wrong damage estimate or an incorrect account of how the loss happened is more serious, since insurers scrutinize affidavits for consistency with the rest of your claim file. Catching it yourself and flagging it is far better than having the insurer catch it first.
An error discovered after the insurer has already paid out doesn't always reopen the claim, but it can. If the mistake affected the amount paid, such as leaving a damaged item off the list, you can usually submit a supplemental claim with a corrected statement. If the error suggested fraud, even an honest one, expect more questions before the insurer treats the rest of your claim the same way.
Reading the affidavit slowly before the notary arrives matters more than reading it quickly in front of them. Notaries aren't checking your facts. Once you sign, the document carries legal weight whether every line in it is accurate or not. Taking the form home, or asking for a day to review it before scheduling the appointment, costs little and avoids the redo.
Before you sign anything
Check your declarations page for every name on the policy, and don't sign an affidavit listing a damage amount you're not sure of. If the payout still feels short once it's settled, compare your coverage against what's available now.
