Duty to Cooperate

The duty to cooperate is a standard condition in liability and property policies that obligates the insured to help the insurer handle a claim. In practice this means giving prompt notice, turning over relevant records, sitting for interviews or an examination under oath, attending depositions and trial, and not doing anything that undermines the defense — such as making side deals, admitting liability, or voluntarily assuming obligations without the carrier's consent. It is the counterpart to the insurer's duty to defend: the carrier funds and directs the defense, and in exchange the insured must participate in good faith.

For a small-business buyer, this obligation is easy to overlook until it costs coverage. Courts have upheld carriers refusing to pay when an insured ignored the defense, hid facts, refused to be deposed, or actively colluded with a claimant against the insurer's interest. To forfeit coverage, the insurer generally must show the lack of cooperation was material and caused prejudice to the defense — a missed phone call is not enough, but disappearing during litigation or falsifying a proof of loss can be. The safest posture is to treat every carrier request as a coverage-preserving requirement and respond promptly.

A practical nuance: the duty to cooperate can create tension when the insurer defends under a reservation of rights, because the insured is being asked to help a carrier that may later deny coverage. In that situation you retain the cooperation obligation but should be careful about what you volunteer regarding coverage-defeating facts, and you may be entitled to independent counsel in some states. Keep clean records, route all claim communications through your agent or adjuster, and never settle, promise, or admit anything without the insurer's written approval — doing so can independently jeopardize your protection.
