Insurance binder
A temporary written agreement that puts coverage in force immediately while the insurer finishes issuing the formal policy.
Also called: binder, temporary insurance, binder of coverage
An insurance binder is a short-term document, issued by an insurer or by an agent with authority to bind coverage, confirming that a policy is in force before the full policy documents are issued. It lists the essentials: the insured, the vehicle, the coverages and limits, the effective date and how long the binder lasts, usually a set number of days or until the policy is issued.
Binders matter most when you need proof of coverage right away, especially when buying a car. A dealer or lender usually will not let you drive off in a financed vehicle without evidence of collision and comprehensive coverage that names the lender as lienholder or loss payee. A binder, or the electronic ID card many insurers issue at purchase, satisfies that requirement.
A binder carries the same coverage as the policy it precedes, so a claim during the binder period is covered on those terms. It is not the same as a car insurance quote, which is only a price estimate that the insurer can still change after checking your record and history. Once the policy arrives, compare its declarations page with the binder and ask about any differences in drivers, vehicles, limits or deductibles.
