A tender letter for defense and indemnity is a formal written demand that shifts responsibility for a lawsuit from you to someone else, usually an insurance carrier or a business partner bound by a contract to cover you. The letter puts that party on notice that you expect them to pay for your defense, cover any settlement or judgment, and step into the case on your behalf. Done right and sent quickly, it’s one of the most consequential documents in managing a liability claim. Done poorly or sent late, it hands the recipient a reason to say no.
When to Send One
The usual trigger is being served with a summons and complaint. Once a third party formally accuses you of causing bodily injury, property damage, or some other compensable harm, the clock starts. You don’t have to wait for a lawsuit, though. A pre-suit demand letter or a written notice of intent to sue is enough reason to tender, because any defense cost you incur from that point forward may be a loss you’re entitled to shift.
Timing matters more than most people realize. The date you send the tender often marks the dividing line for who pays which defense costs. Fees you incur before tendering are usually yours. Fees incurred after a proper tender lands on the right desk become the recipient’s responsibility. A tender sent 20 months into litigation, after extensive discovery, has been found insufficient as a matter of law. Send the letter within days of learning about the claim, not weeks.
Tender letters arise from two main sources. One is an insurance policy, where you’re asking your carrier (or a carrier that added you as an additional insured) to honor its coverage obligation. The other is a contractual indemnity clause. Construction agreements, service contracts, and commercial leases routinely require one party, typically the one performing the work, to indemnify and hold harmless the other for incidents connected to that work. If a visitor is injured on a job site and sues the property owner, the owner tenders the defense to the general contractor under the indemnity clause. The contractor may then tender down to a subcontractor whose work allegedly caused the injury.
Defense and Indemnity Are Two Different Things
A tender letter typically demands two things, and the distinction matters. The duty to defend means the recipient must provide and pay for your legal representation. The duty to indemnify means the recipient must pay any judgment or settlement entered against you. These are separate obligations, and one can exist without the other.
The duty to defend is broader and kicks in earlier. Courts generally compare the allegations in the complaint against the terms of the policy or indemnity agreement. If the complaint alleges facts that could potentially fall within coverage, the insurer must defend, even if those allegations turn out to be groundless. The duty to indemnify depends on actual liability and is only triggered once a court determines you’re legally responsible and the loss falls within coverage.
This matters practically because an insurer might owe you a defense for the entire lawsuit but ultimately owe you nothing on indemnity if the facts at trial show the loss wasn’t covered. Your letter should explicitly demand both. A tender that asks only for a defense may not preserve your right to have the judgment paid.
What to Put in the Letter
A tender letter needs to be specific enough that the recipient can’t plausibly claim confusion about what you’re asking for or why. Vague demands get slow responses or outright denials. Include:
- The full legal caption of the lawsuit (party names, court, case number), with a complete copy of the pleading attached.
- The insurance policy number and effective dates, or the specific contract containing the indemnity language. Quote the relevant section and paragraph of the indemnity or hold harmless clause rather than making the recipient hunt for it.
- The date and location of the alleged incident, so the carrier can confirm the event falls within the coverage period and scope.
- An explicit demand for both a defense and indemnification. Spell out that you expect appointed and paid defense counsel plus coverage of any judgment or settlement.
- A reasonable response deadline, typically 15 to 30 days depending on the jurisdiction and policy terms.
Attach copies of the summons and complaint, the relevant insurance declarations page or certificate of insurance, and the executed contract with the indemnity provisions. The more documentation you include upfront, the harder it is for the recipient to stall by requesting more information.
If you’re being tendered as an additional insured rather than a named insured, understand that your coverage is usually narrower, limited to claims arising from the named insured’s work or operations. The policy language governing additional insured coverage will drive whether your tender is accepted.
How to Send It
Delivery method matters because you may need to prove the recipient received the demand. Certified mail with return receipt requested remains the most reliable option for creating a paper trail. Many large carriers also accept tenders through dedicated claims portals or designated email addresses; check the policy or the carrier’s website. If you use electronic submission, save confirmation receipts and screenshots.
Some policies specify an approved method of notice. Follow that method exactly. A technically deficient delivery can give the carrier an excuse to claim it never received proper notice. Verify the right claims contact before mailing anything. Sending the letter to a broker instead of the carrier, or to the wrong carrier when multiple policies apply, is a common and avoidable mistake.
After the letter goes out, expect a waiting period while the recipient reviews. Response timelines vary; some state insurance regulations require acknowledgment within 15 business days, while others allow longer. Don’t sit idle. Keep coordinating your own defense, because if the tender is ultimately rejected, you’ll want to have protected your interests in the meantime.
What a Response Will Look Like
Three outcomes are possible, and a clean acceptance with no strings attached is the least common.
Acceptance
The carrier agrees the claim falls within coverage and appoints defense counsel. From that point, the carrier controls the defense strategy and pays the legal bills. Even here, watch the scope of what’s being accepted. The carrier may accept the duty to defend but reserve judgment on indemnity until the facts develop.
Reservation of Rights
This is the most common response. The carrier agrees to provide a defense but isn’t yet committing to pay a final judgment. The reservation of rights letter identifies specific policy provisions or exclusions that might apply and warns that coverage may later be denied depending on what the investigation reveals. If an insurer simply defends without sending a reservation of rights letter, it may waive its right to contest coverage later.
A reservation of rights letter can create a conflict of interest. The insurer’s appointed attorney technically represents you, but the carrier is simultaneously building a case for why it might not owe you anything. Most jurisdictions recognize this tension and give you the right to select independent counsel, sometimes called Cumis counsel, paid for by the insurer when a genuine conflict exists. States handle this differently. Some grant independent counsel automatically whenever a reservation of rights letter issues, others require a showing that an actual conflict exists, and a few allow the insurer to keep its own appointed counsel in place regardless. The insurer’s obligation to pay independent counsel fees is typically capped at the rates it normally pays defense attorneys in similar cases, so don’t expect a blank check.
Don’t treat a reservation of rights as an acceptance. Read it carefully, evaluate whether independent counsel is warranted, and respond in writing if you disagree with the coverage positions being staked out.
Rejection
The carrier denies the tender entirely, arguing the claim falls outside coverage, the policy wasn’t in effect at the time of the loss, or some exclusion applies. Rejection doesn’t end the matter. It starts a new phase.
What Late Tender Costs You
Most occurrence-based policies require notice of a claim “as soon as practicable” or within a “reasonable” time. Miss that window and the carrier has grounds to deny the tender.
How much latitude you have depends on where you are. A majority of states apply the notice-prejudice rule: the insurer can’t deny based solely on late notice unless it can show the delay actually harmed its ability to investigate or defend. In those jurisdictions, if the insurer suffered no real prejudice, late notice alone won’t kill coverage.
Not every state is so forgiving. Some treat timely notice as a fundamental condition of coverage and will void the policy’s obligations regardless of prejudice. And for claims-made policies, where coverage depends on the claim being reported during the policy period, the notice-prejudice rule generally doesn’t apply at all. Missing the reporting window on a claims-made policy is usually fatal to coverage.
Even in prejudice-friendly jurisdictions, late tender creates practical problems. Defense costs you incurred before tendering typically stay yours. And the further into litigation you are when you finally tender, the weaker your position becomes.
If the Tender Is Rejected
If the rejection is wrong, you have options.
Declaratory Judgment Action
You can file a lawsuit asking a court to declare your rights under the policy or indemnity agreement. Under federal law, any court of the United States may declare the rights and legal relations of any interested party in a case of actual controversy, and that declaration has the force of a final judgment.1Office of the Law Revision Counsel. 28 USC 2201 – Creation of Remedy State courts hear these actions as well. The court examines the policy language, the complaint’s allegations, and the facts of the loss to determine whether the carrier owes a defense and indemnity. This is the standard mechanism for resolving coverage disputes, but it takes time, and meanwhile you’re still paying your own defense costs in the underlying case.
Bad Faith Claims
If the rejection was unreasonable, you may have a bad faith claim. Consequences for a carrier that wrongfully refuses to defend can be severe. The insurer may be liable for the full amount of any judgment entered against you, not just the portion within policy limits. If the claim involves an unreasonable refusal to settle within policy limits, the insurer can be held responsible for the excess judgment above those limits. Courts in egregious cases also award consequential damages, emotional distress damages, and punitive damages.
An insurer that wrongfully refuses to defend also risks estoppel, meaning it may lose the right to raise policy defenses it could have otherwise relied on. A carrier can’t sit on the sidelines while you fend for yourself and then show up after the verdict to argue the loss wasn’t covered. If the carrier wanted to contest coverage, it needed to either defend under a reservation of rights or seek a declaratory judgment before walking away.
A Reimbursement Wrinkle
One point worth knowing before you celebrate a defense under reservation of rights: in most jurisdictions, if a carrier defends you under a reservation and coverage is ultimately found not to apply, the carrier can seek reimbursement of the defense costs it paid. A minority of states prohibit this recovery unless the policy expressly allows it, but don’t count on being in one of those jurisdictions. A defense provided under a reservation of rights is conditional, not free.
Mistakes That Undermine a Tender
The errors that most often turn a valid tender into a denied one:
- Tendering to the wrong party, like a broker instead of the carrier, or the wrong carrier when multiple policies are in play.
- Stating that an indemnity obligation exists without quoting or attaching the actual contract clause.
- Demanding only a defense and forgetting indemnification.
- Waiting to “see how it goes” before tendering. Tender immediately and let the carrier decide how the defense should proceed.
- Treating a reservation of rights letter as an acceptance when it’s a conditional defense with coverage positions still in play.
A well-drafted tender letter sent promptly to the right party forces the entity that agreed to bear the risk to actually bear it, or to explain in writing why it won’t, which gives you the evidence you need to hold it accountable.
