A more thorough explanation:

Definition: Restor is a term used in the insurance industry, especially in marine underwriting. It refers to the recourse that insurers have against each other based on the date of their insurance. It can also refer to the recourse that marine insurers have against a ship's master if a loss occurs due to their fault or negligence. Additionally, it can refer to the recourse that one has against a guarantor or other person under a duty to indemnify.

Example: If two insurers have provided coverage for the same risk, the insurer who provided coverage first has the right to claim against the other insurer in case of a loss. This is an example of restor.
