What Is Knock-for-Knock Agreement in Car Insurance?

The knock-for-knock agreement was established to reduce the complex processes involving claims from third-party and own damages insurance. In this agreement, drivers agree to pay for their damages without assigning liability.

When you get into an accident, you must establish who is liable before claiming damages. The road to a settlement is often time-consuming and costly and may involve several negotiations between adjusters and lawyers.

The knock-for-knock agreement allows motorists to swiftly resolve any issues from an accident without following complex legal processes. However, this agreement is only applicable when both drivers have comprehensive coverage, and their insurers have a knock-for-knock agreement.

What Is the Knock-for-Knock Agreement?

All vehicles are legally required to have minimum coverage, depending on your state. Theoretically, in an accident, the negligent party is often liable for compensation. However, if the other driver has only third-party coverage, you may only be able to recover some of your damages.

In some cases, if the accident caused extensive damages, you may end up in lengthy litigation processes as you try to recover compensation. This process is complex and often expensive, and most insurance companies would instead not go this route.

The knock-for-knock agreement applies in such cases. In the above scenario, each insurance company pays for damages for their policyholders. While it is not mandated by law as a regulatory requirement, it is established as a general agreement between insurers.

If your insurer has a knock-for-knock agreement with the other driver’s insurance company, you do not have to drag the matter to court or deal with time-consuming negotiations.

A knock-for-knock agreement means no blame is apportioned to one motorist. However, if you prove negligence, you can ask the liable driver to use their coverage for your damages. In this case, you might need to hire a car accident attorney to negotiate on your behalf.

More Factors to Consider Under the Knock-for-Knock Agreement

The knock-for-knock agreement helps insurers significantly speed up the claims and settlement process. As a motorist, before settling on this agreement, there are a few factors to consider.

  • You must check with your insurance company before settling for a knock-for-knock agreement, as not all insurers offer this service.
