Binder
A short-term written confirmation that coverage is in force while the full policy is being issued, often used as proof of insurance at a home closing.
Also called: insurance binder, binder of insurance, temporary insurance
A binder is a temporary contract of insurance. It confirms that coverage is in force from a stated date while the insurer finishes underwriting and issues the formal policy. Agents commonly produce one the day you buy or close on a house, since the lender needs proof of insurance before it funds the loan. A binder lists the insured, the property, the coverages and limits, the effective date, and the mortgagee.
Binders are short-lived. Many run 30 to 90 days, and state law often sets a maximum length. During that time the binder is a real contract: a loss that occurs while it is in effect is covered under its terms, usually the standard form the insurer will issue. When the policy arrives, the binder is replaced by it.
The pitfalls are practical. Check that the binder's effective date matches your closing date, that the mortgagee name and address are right, and that the policy is actually issued before the binder expires. An insurer can also cancel a binder, usually after reviewing the application or an inspection, so do not treat it as a final approval. If the final policy shows different limits or exclusions than the binder, raise it with your agent immediately.
