Texas Proof of Claim is a written statement filed by a creditor to assert their right to payment from a debtor. It is used when a debtor files for bankruptcy and the creditor has a claim against the debtor. There are two types of Texas Proof of Claim: secured and unsecured. A secured claim is a claim that is backed by collateral, such as a mortgage or car loan. An unsecured claim is a claim that does not have collateral and is not backed by any property. Both types of Texas Proof of Claim must include information about the creditor, the debtor, and the amount of the claim. The creditor must also provide documentation to validate their claim.
