Getting sued can feel like the floor just dropped out from under you. Whether the lawsuit names a business, property owner, employer, contractor, nonprofit, or individual, one of the first practical questions is often: Will insurance pay for the defense?
In many situations, the answer may depend less on whether you have insurance and more on how the lawsuit is tendered to the insurer. A delayed, incomplete, or poorly framed tender can complicate coverage discussions, create unnecessary expense, and make it harder to preserve rights that may exist under the policy.
In this post you’ll learn how to tender a lawsuit to an insurance company the right way, what documents usually matter, what insurers look for, how reservation-of-rights letters fit into the picture, and where policyholders often run into trouble. If you want a deeper primer on the coverage framework behind this process, this overview of getting an insurer to step in and defend helps connect the dots.

In general terms, tendering a lawsuit means giving the insurance company formal notice of the claim or suit and asking it to provide the defense and any other coverage that may apply.
That sounds simple, but there are usually several moving parts:
This matters because liability policies often include notice and cooperation conditions. The Insurance Information Institute explains that policyholders are typically expected to notify the insurer as soon as practicable when they become aware of an occurrence that may result in a claim, and to cooperate in the investigation and defense of the matter (III). The same organization also notes that when there is a lawsuit, the insurer is to be notified immediately and provided the suit papers (III).
A proper tender often does more than “open a claim.” It can shape the entire defense process.
If the claim potentially falls within coverage, many jurisdictions apply some version of the four-corners or eight-corners rule, meaning the insurer evaluates the duty to defend primarily by comparing the policy language to the allegations in the complaint (American Bar Association; American Bar Association). That means the way the tender package presents the complaint and policy can influence how quickly the insurer focuses on the potentially covered allegations.
It also matters because the duty to defend is often broader than the duty to indemnify. Courts and commentators frequently describe defense obligations as being triggered when the complaint alleges claims that are potentially covered, even if coverage is later disputed or narrowed (American Bar Association; III).
That is one reason a careful tender can be so important: it frames the request around potential coverage, not around proving the entire case from day one.
