When you make a property or contents claim, your insurer may ask you to complete a proof of loss, a formal statement describing what happened and what was lost or damaged. Many insurers require this statement to be sworn or declared before a commissioner or notary.
What a proof of loss usually covers
- the date, time and cause of the loss;
- a description or list of damaged or stolen property;
- the amount being claimed;
- information about other insurance and ownership of the property.
Your insurer or adjuster will usually provide the form and explain what needs to be included.
Getting it commissioned
- Complete the form fully, attaching any schedules or inventories the insurer requires.
- Do not sign it in advance.
- Bring valid photo ID for each person who must sign (for example, all named insureds).
- At the appointment, we administer the oath or declaration, witness your signature and apply our stamp.
Important reminders
- Pay attention to your insurer’s deadline for submitting the proof of loss.
- Be accurate. A sworn proof of loss is a serious legal statement.
- We don’t assess your claim, negotiate with insurers or advise on coverage. For that, speak with your adjuster, broker or a lawyer.
