What Is an Insurance Binder? California Rules

An insurance binder is a short written agreement that puts your insurance in force before the full policy is issued. It names you, the property, the coverage and how much, the insurer, the agent who issued it and the start date. Until the policy shows up, the insurer is on the hook for that coverage. California's Insurance Code section 382.5 goes a step further. A binder issued under it "shall be deemed an insurance policy for the purpose of proving that the insured has the insurance coverage." It lasts for the period it states, up to 90 days, or 90 days if it states none, and it ends when the policy is issued.^[1] So yes, a binder is proof of insurance. It's also a real contract of insurance, just a temporary one.

Most people first see a binder at a home closing, when escrow needs proof of homeowners insurance before the lender will fund. If you're buying a home and need coverage bound in time, request a homeowners quote and give us your closing date. Below: what goes in a binder, who can issue one, how long it lasts, and how it's different from a certificate of insurance and a declarations page.

Insurance binder

A written, short-term agreement issued by an insurer or its authorized agent that provides temporary insurance coverage, on the usual terms of the policy it anticipates, until the policy is issued or the binder expires.

What is an insurance binder?

The California Department of Insurance defines a binder as "a short-term agreement that provides temporary insurance coverage until the policy can be issued or delivered."^[3] IRMI's definition is similar: a legal agreement issued by an agent or an insurer to provide temporary evidence of insurance until the policy is issued. IRMI adds that a binder should be in writing, have a fixed time limit, name the insurer, and state the amount and type of coverage and, for property, the perils covered.^[4]

Binders exist because it takes an insurer time to issue a policy. The underwriter may want an inspection. The forms have to be put together. A big or unusual risk may go to a senior underwriter. Meanwhile, the house closes escrow, the truck leaves the lot, or the lease starts. The binder covers you in between. And the coverage is real. If you have a covered loss the day after binding, it gets paid on the terms the binder describes.

If the binder leaves something out, California law fills it in. Unless the binder clearly says otherwise, it's treated as including all the usual terms of the policy it's standing in for, plus any endorsements it names.^[1]

What does an insurance binder contain?

California's statute spells out what a binder has to include to count under section 382.5:^[1]

Required item	What it looks like on a homeowners binder
Name and address of the insured	The buyer or buyers taking title
Additional named insureds, mortgagees or lienholders	The lender, with its loan number and mortgagee clause
Description of the insured property, if applicable	The property address
Nature and amount of coverage	For example, dwelling, other structures, personal property, loss of use and liability limits, and the deductible
Special exclusions not in a standard policy	Any unusual exclusion, such as a wildfire or roof limitation
Identity of the insurer	The legal name of the insurance company, not only the agency
Identity of the agent executing the binder	The agent or broker who issued it
Effective date of coverage	Usually the closing date
Binder number, or policy number for an extension	The reference the lender uses to follow up

A lot of binders are written on the ACORD 75 form, and lenders often get property evidence on an ACORD 27. Our pages on ACORD 75, the insurance binder and ACORD 27, evidence of property insurance go through those forms field by field. Here's a made-up example, not a real document: a binder issued June 10, effective at 12:01 a.m. on June 12, naming the buyers and their lender, for a $650,000 dwelling limit with a $2,500 deductible, expiring in 60 days or on issuance of the policy.

Who issues an insurance binder?

The insurer, or an agent the insurer has authorized to bind. In California, an agent's license rides on that authority: the Insurance Commissioner may suspend or revoke the license of an agent who issues, or claims to issue, a binder the insurer has not authorized.^[1] A lender may also refuse a binder when the agent does not provide written evidence of the authority to bind.^[1]

In practice, you get it from the agent or broker who placed your policy. If your broker can't bind with that carrier, it asks the carrier, or the managing general agent that underwrites the program, for the binder (see our guide to what an MGA is). Whoever you ask, you'll end up back with the person who sold you the policy.

How long does an insurance binder last in California?

A binder under section 382.5 is good for the period written on it, up to 90 days from the date it was signed. If no period is written, it lasts 90 days. It stops being valid the day the policy is issued. And if a binder just runs out, that doesn't count as a cancellation or nonrenewal under the statutes that limit an insurer's right to cancel.^[1]

That last part matters. The protections you get when a policy is cancelled or nonrenewed don't apply when a binder runs out. If your binder is close to its end date and you still don't have a policy, call your broker. Don't assume you're still covered.

Section 382.5 has two limits you should know about. It doesn't apply to life or disability insurance, or to binders for $1 million or more of insurance.^[1] Larger temporary coverage falls under the older Insurance Code section 382 on "covering notes." That section also requires a policy to be issued within 90 days, unless the Commissioner approves a longer extension.^[2]

Why do mortgage lenders and escrow ask for a binder?

A lender won't fund a loan on an uninsured house, and on closing day the policy usually doesn't exist yet. The binder is what lets escrow close. It shows the lender that a named insurer has to cover the home from the closing date, with the lender listed as mortgagee.

California gives you real leverage here as a buyer. If a contract calls for proof of insurance and someone refuses a compliant binder without reasonable cause, the law treats that as a breach of contract. The other side can seek an injunction, damages and reasonable attorney's fees.^[1] The statute lists what counts as reasonable cause to refuse:^[1]

The coverage or its terms are inadequate or inappropriate for the lender's, vendor's or lessor's interest.
The insurer fails financial standards the lender lawfully applies to all insurers for that type of loan.
The lender cannot confirm that the insurer is licensed in California for that line.
The agent does not give the lender written evidence of authority to bind.
The binder does not comply with section 382.5.

If escrow rejects your binder, ask which of these five reasons they're using. Most rejections can be fixed. Usually it's a missing loan number, the wrong mortgagee clause, or a dwelling limit below what the lender requires. The Department of Insurance also recommends checking that the application or binder shows the limits, deductibles and coverage you bought, the insurer's name, the start and end dates and the insured property.^[3]

How is a binder different from a certificate of insurance or a declarations page?

People mix these three up because all of them show coverage. Only the binder is a temporary contract.

	Insurance binder	Certificate of insurance	Declarations page
What it is	A temporary contract of insurance	A summary of coverage that already exists	The first pages of the issued policy
When you get it	Before the policy is issued	Any time after coverage is in force	When the policy is issued
Does it create coverage?	Yes, for its term	No	It is part of the policy that does
How long it lasts	Up to 90 days in California under 382.5, or until the policy issues^[1]	Reflects coverage on the date issued	For the policy period
Who relies on it	Lenders, escrow, lessors	Landlords, clients, project owners	You, your adjuster and your broker
Typical form	ACORD 75	ACORD 25 (liability)	Insurer's own form

A certificate of insurance tells someone else what coverage you have. It doesn't give the certificate holder any rights of its own. A declarations page is the summary sheet at the front of the policy: named insured, policy period, limits, deductibles, premium and forms. Once the policy is issued, the declarations page and the policy forms decide every claim. The binder describes what the policy is going to be. The declarations page shows what it actually is. For a one-paragraph refresher, see the insurance binder glossary entry.

Do you have to pay for an insurance binder?

Usually not separately. A binder is the temporary version of the policy you're buying, and your premium pays for the policy. Carriers often want the first payment, or proof it's coming through escrow, before they'll bind. Check that the binder, and the policy after it, match what you paid for.

Frequently asked questions

Is an insurance binder just proof of insurance?

It's more than proof. A binder is a temporary contract. Until the policy is issued, the insurer has to provide the coverage the binder describes. In California, a binder that meets Insurance Code 382.5 is also deemed a policy for the purpose of proving you have the coverage.

Where do I get my insurance binder?

From the agent or broker who placed your policy, or from the insurer directly. The binder has to name the insurer and the agent who issued it, so ask whoever sold you the policy. If it's for a closing, give them the lender's mortgagee clause and loan number so they get it right the first time.

How long is a binder good for in California?

For the period written on it, up to 90 days from the date it was signed, or 90 days if no period is written. It ends as soon as the policy is issued. Binders for $1 million or more of coverage fall under a separate covering-note rule that also expects a policy within 90 days.

Can a lender refuse my insurance binder?

Only with reasonable cause. California law lists the reasons, like inadequate coverage, an insurer the lender cannot confirm is licensed, or an agent who cannot show authority to bind. A lender that refuses a compliant binder without reasonable cause is treated as in breach of the contract.

What does a binder look like?

Usually one or two pages, often on the ACORD 75 form or the insurer's own layout. It shows the insured, any lender or other interest, the property, coverages and limits, deductibles, the insurer, the issuing agent, the effective date and time, the expiration, and a binder number.

The Bottom Line

An insurance binder is your coverage in writing before the policy exists. In California it can last up to 90 days, it counts as proof of insurance, and a lender can't refuse a compliant one without reasonable cause. Check that it names the right insurer, lender, limits and dates. Then keep an eye out for the policy, because your claims will be decided by the declarations page, not the binder. If you're closing on a home, start a homeowners quote early enough that the binder is ready before escrow asks for it.
