Texas Correction-Revision-Endorsement To Existing Policy (CREEP) is a document used by Texas insurance providers to make corrections, revisions, or endorsement to existing policies. There are three types of CREEP: 1. Correction Endorsement: this is used to correct errors or omissions in the existing policy and bring it in line with the original intention of the insurance provider. 2. Revision Endorsement: this is used to update the policy in line with changes in legislation or changes in the insured’s circumstances. 3Endorsementnt: this is used to add, delete, or modify coverage to the existing policy. CREEP is an important document as it helps ensure that the insurance provider and the insured are both operating under a consistent and up-to-date policy. It is also important to note that any changes to an existing policy must be approved by the insurance provider before they can take effect.
