Supplementary payments: extras liability pays beyond the limit
Your liability limit is not the whole bill. Defense costs, bail bonds, appeal bonds, post-judgment interest and trial lost wages sit on top, until they stop.
The limit on your liability coverage is the most your insurer will pay in damages to the people you hurt or whose property you damage. It is not the most the policy will ever spend. A separate clause, usually titled Supplementary Payments, makes the insurer pay a list of other costs "in addition to" the limit: your legal defense, certain bonds, interest on a judgment after it is entered, and a few smaller items. Those payments stop at specific points, and the clause's wording differs enough between insurers that you should read your own.
Where the clause sits and why it exists
Liability coverage is a promise to do two things when you cause a crash: pay damages you are legally responsible for, up to a limit, and defend you against the claim. If defense costs came out of the limit, a $50,000 policy facing a $40,000 lawyers' bill would leave almost nothing for the person who was hurt. Personal auto policies avoid that by treating the defense, and a short list of procedural costs, as an obligation outside the limit.
Two sample personal auto policies from licensed insurers show the standard shape. A Young America Insurance Company Illinois personal auto policy (form dated August 2022) says that "in addition to our limit of liability, we will pay all defense costs we incur," and then lists five supplementary payments. A National General New York personal auto policy (form dated 2009) has a similar list with seven items. Neither is the form your insurer used, and your company's version may use different dollar amounts or add or drop items. Treat them as a map of the territory.

The list, item by item
The two sample policies pay the following on behalf of a covered person, in addition to the limit.
| Payment | What the sample wording says | What it means in practice |
|---|---|---|
| Defense costs | Insurer pays all defense costs it incurs, in addition to the limit | The lawyer the insurer hires, expert witnesses and the cost of getting the case to trial do not reduce what is available to settle or pay a judgment |
| Bail bonds | Up to $250 for bail bonds required because of an accident, including related traffic law violations; the accident must result in covered bodily injury or property damage | A small reimbursement if you are arrested and must post bail after a crash for a related traffic offense |
| Appeal bonds and attachment-release bonds | Premiums on appeal bonds and bonds to release attachment in any suit the insurer defends | The cost of the bond, not the bond amount, when a judgment is appealed or property has been frozen before judgment |
| Post-judgment interest | Interest accruing after a judgment is entered in any suit the insurer defends; the duty ends when the insurer offers to pay the part of the judgment within the limit | Interest that builds after a verdict but before the insurer pays |
| Lost earnings | Up to $50 a day for loss of earnings, but not other income, because of attendance at hearings or trials at the insurer's request | A small daily allowance for wages you lose when the insurer asks you to attend |
| Other reasonable expenses | Reasonable expenses incurred at the insurer's request | Costs such as travel to a deposition that the insurer asks you to incur |
| First aid (New York sample only) | Expenses a covered person incurs for first aid to others at the time of the accident | Bandages or a first-aid purchase at the scene |
| Taxed costs (New York sample only) | All costs taxed against a covered person in any suit the insurer defends | Court costs a judge assigns to the losing side |
A few notes on reading that table.
The dollar amounts are small, and they differ. The bail bond figure in both samples is $250 and the lost-earnings figure is $50 a day. Your own form may say something else, and a state-specific endorsement can replace the clause entirely. Do not rely on a number from a different company's policy.
"At our request" matters. The lost-earnings and "other expenses" items turn on the insurer asking you to do something. If you take time off to attend a hearing the insurer did not ask you to attend, the clause may not apply. Ask the claims representative before you incur the cost, and get the answer in writing.
Only suits the insurer defends count. Interest, appeal bonds and attachment bonds are all tied to "any suit we defend." If the insurer has denied coverage and refused to defend, the clause does not operate the same way, and the analysis shifts to whether the refusal was wrongful. sued after a crash: how your insurer's duty to defend works covers when defense is owed.
The sample bail bond item requires covered harm. The accident must result in bodily injury or property damage covered under the policy. A traffic stop with no covered loss does not trigger it.
Defense costs: the largest item and why they sit outside the limit
Defense is by far the biggest supplementary payment. A contested injury lawsuit can generate attorney time, medical experts, accident reconstruction and court reporters over several years. In the sample forms, all of that is the insurer's cost "in addition to our limit," so spending $60,000 on defense does not leave you with a $60,000-smaller policy.
Two cautions:
- This is how personal auto policies are commonly written, not a law of nature. Some policies in other lines, such as certain professional or commercial liability forms, pay defense costs from inside the limit. Check the declarations and the liability section of your own policy rather than assuming.
- The sample forms say defense ends when the limit is exhausted. The Illinois form states that the insurer's duty to settle or defend ends when its limit of liability has been exhausted. That means a policy with a limit that is used up by paying a settlement or judgment can stop defending the remaining claims. This matters when several people are injured, as explored in how insurers split limited coverage among several injured claimants and multiple claimants, one policy limit: interpleader and pro rata splits.
Interest on a judgment and the cutoff date
Once a court enters a judgment, the amount starts earning interest at a rate set by state law. The sample wording makes the insurer responsible for interest "accruing after a judgment is entered" in a suit it defends, and it stops when the insurer offers to pay the part of the judgment that does not exceed the limit.
Older wording, which a federal appeals court examined in Knippen v. Glens Falls Insurance Co. (D.C. Cir. 1977, 564 F.2d 525), covered "all interest on the entire amount of any judgment" accruing after entry and before the insurer paid, tendered or deposited in court its share. The court read that sentence as written. In that case the insurer wrote a letter offering its $50,000 limit "in full and final payment," and the claimant refused. The court held the conditional offer was not a tender, because the insurer had not given up control of the money, so interest on the full $300,000 judgment kept running until an unconditional tender months later. The court also said the clause's promise to pay costs did not end when the insurer withdrew from the defense. The decision turned on the policy language and does not state a general rule, but it shows how the insurer's timing and the exact words of its offer can decide who pays months of interest.
Prejudgment interest is different
Interest that builds between the crash (or the filing of the suit) and the judgment is a separate question, and the supplementary payments list in the sample forms does not mention it. In Dairyland Insurance Co. v. Douthat (Virginia Supreme Court, 1994, 248 Va. 627), the court held that an insurer has no duty to pay prejudgment interest above its policy limits unless the contract says so. It distinguished post-judgment interest, which a Virginia statute makes mandatory once a judgment is entered. The decision rests on Virginia law and the policy wording involved, and other states have decided the question differently, so the answer for your case depends on your state and your form. Check the state's rules with your attorney or the state insurance commissioner and see the Virginia guide for background on that state's rules.
When the extras stop
The payments continue until a defined event. Here are the usual endings.
- The limit is exhausted. In the Illinois sample, the duty to settle or defend ends when the limit has been exhausted. The exact words of each policy decide whether an offer, a deposit or an actual payment counts as exhausting the limit.
- Interest stops when the insurer offers or pays its share. In the sample wording, post-judgment interest ends when the insurer offers to pay the part of the judgment that does not exceed its limit. In Knippen, the policy said paid, tendered or deposited, and the court insisted on an unconditional surrender of the funds.
- The suit ends. Appeal bonds, bonds to release attachment and trial lost-earnings items are tied to a suit the insurer defends, so they end with the case.
- The insurer wins or settles within limits. If the case settles for an amount inside the limit and the claimant signs a release, defense costs stop at that point. See Settlement paperwork: releases, liens and Medicare reimbursement for what the release should say.
- Coverage is denied. If the insurer denies coverage, supplementary payments tied to "suits we defend" are no longer available through the policy, which is why a wrongful denial can lead to a bad faith dispute, discussed in insurance bad faith explained.
Of these, the practical risk for an insured is the insurer's tender strategy: paying the limit to the claimant to end the defense when the claim is clearly worth more than the policy. Whether the insurer may walk away that way depends on policy wording and state law. In Knippen the court described an earlier D.C. decision, National Union Insurance Co. v. Phoenix Assurance Co. (D.C. 1973), which held that under that policy's language the insurer's defense duty ended when it deposited the policy limit in court, and it declined to extend that reasoning automatically to a different clause. Two policies with similar-looking clauses can lead to different results, and that is a question for a licensed attorney in your state.
A worked example: a $100,000 limit and a judgment
Say you cause a crash, and the injured driver sues. Your bodily injury limit is $100,000 per person. All numbers below are invented to show the arithmetic and are not market data.
- The insurer hires a defense firm. Over two years, defense costs (lawyers, a medical expert and a reconstruction expert) total $62,000.
- The case goes to trial. The jury awards $240,000. The court enters judgment for $240,000 and assesses $4,500 in taxed court costs against you.
- State law sets post-judgment interest at 5% a year (hypothetical). The insurer pays its limit unconditionally 60 days after judgment. Interest on $240,000 for 60 days is about $1,973 ($240,000 x 0.05 x 60/365).
| Item | Who pays | Amount | Inside or outside the limit |
|---|---|---|---|
| Damages up to the limit | Insurer | $100,000 | Inside |
| Defense costs | Insurer | $62,000 | Outside |
| Taxed court costs (if the form covers them) | Insurer | $4,500 | Outside |
| Post-judgment interest to the date of payment | Insurer | $1,973 | Outside |
| Judgment above the limit | You | $140,000 | Not covered |
| Interest on the $140,000 after the insurer pays | You | accrues at 5% a year, about $19 a day | Not covered |
The insurer's total spending is about $168,473, well above the $100,000 limit. Yours is the $140,000 gap plus the interest that keeps running on it. Supplementary payments make the policy more generous than its limit suggests, but they do not close the gap above the limit. That gap is what an umbrella policy or a higher primary limit is for, and what happens when damages exceed your liability limits and excess judgments: when a verdict is larger than your policy limit describe what happens next.
Now vary the facts. Suppose the insurer appeals and the court requires a bond of $250,000 to pause collection while the appeal runs. In the sample forms, the insurer pays the premium on that bond, not the bond principal, and interest continues to build on the judgment during the appeal. If the appeal fails, more interest has accrued. That is one reason timing of the insurer's payment of its limit matters.
Tenders, demands and what to do when a limit is likely to be exceeded
When an injury is serious and the damages obviously exceed the limit, three events tend to occur in sequence: the claimant's lawyer sends a time-limited demand to settle for the limit, the insurer decides whether to accept, and you may receive an "excess letter" warning that the claim could exceed your coverage.
- A demand for the full limit may be one the insurer should accept. If the insurer refuses a reasonable demand and a bigger judgment follows, state law may let you hold it responsible for the excess. See refused settlements and excess judgments: the insurer's duty to settle and the glossary entry for policy limits demand.
- If the insurer pays its limit and withdraws, ask what happens to the defense. Under some forms, the defense ends. Under others, the insurer must keep defending until the claims against you are resolved. The answer is in the words of your policy and in your state's law.
- Hire your own lawyer when excess exposure is real. The insurer's lawyer is retained to defend you, but you are entitled to consult counsel about the portion above your limit. Cost is yours, but the advice is worth it.
- Never let the insurer's payment of the limit pass without reading the release. Make sure it discharges you personally.

Common questions
Do defense costs ever reduce my coverage?
Not in the sample personal auto forms, which pay defense costs in addition to the limit. Some policies in other lines work differently, with defense costs eroding the limit, so confirm in your own policy. The declarations page lists the limit, and the liability section of the form says how defense is treated. liability limits decoder helps with reading limit notation.
Does the insurer pay my bail if I am arrested after a crash?
Only a small amount, and only for specific situations. The sample wording pays up to $250 of the cost of a bail bond required because of an accident, including related traffic law violations, and the accident must result in covered injury or damage. It does not pay fines, criminal defense costs or bail on non-traffic charges.
Does the insurer pay interest on a judgment above the limit?
In the sample wording the insurer pays post-judgment interest "accruing after a judgment is entered" in a suit it defends, until it offers or pays its share. Older, broader wording, as in Knippen, covered interest on the entire judgment. Either way, interest that accrues after the insurer has paid its limit on the portion above the limit is generally yours.
Can I be paid for time off work to attend my trial?
The sample forms pay up to $50 a day of lost earnings, not other income, for attending hearings or trials at the insurer's request. If the insurer did not request your attendance, or if you lose income that is not wages, the clause may not apply. Ask before you take the day off.
Key takeaways
- Defense costs and the other supplementary payments are paid in addition to your liability limit in the sample personal auto policies; confirm the wording of your own.
- The supplementary list is short and specific: defense, small bail bond amounts, bond premiums, post-judgment interest, a daily lost-earnings allowance and other expenses the insurer requests.
- The payments stop at defined moments: when the limit is exhausted, when the insurer offers or pays its share, or when the suit ends. The wording of the insurer's offer can change who pays the interest.
- Prejudgment interest is not on the sample list, and courts differ on whether an insurer owes it above the limit.
- None of this covers a judgment above your limit, so excess exposure needs a higher limit or an umbrella policy and early advice from a licensed attorney.
