California Code of Civil Procedure Section 998 is a procedural weapon that shifts the financial risk of trial and forces opponents to reconsider their settlement positions. When a plaintiff or defendant serves a CCP 998 offer to compromise, they create a cost-shifting mechanism that can add tens of thousands of dollars in expert witness fees and litigation costs to the losing side's exposure. Understanding how this statute operates is essential for anyone navigating a California personal injury case.

What Is a CCP 998 Offer California and How Does It Work?

Code of Civil Procedure Section 998 allows any party to serve a written settlement offer on the opposing party at least ten calendar days before trial. The offer must be explicit, unconditional, and include an acceptance clause stating that if accepted, judgment will be entered accordingly. The receiving party has thirty days to accept, or the offer is deemed withdrawn. If the matter proceeds to trial and the offeree fails to obtain a more favorable judgment, statutory cost-shifting consequences are triggered.

The mechanism is straightforward but powerful. A plaintiff who makes a CCP 998 offer california for $100,000.00 (One Hundred Thousand Dollars) and later recovers $125,000.00 (One Hundred Twenty-Five Thousand Dollars) at trial has beaten their own offer. The defendant is then liable not only for the judgment but also for the plaintiff's post-offer costs, including expert witness fees under Civil Code Section 998(c)(1). Conversely, a defendant who offers $100,000.00 (One Hundred Thousand Dollars) and the plaintiff recovers only $75,000.00 (Seventy-Five Thousand Dollars) at trial can recover their post-offer costs from the plaintiff, creating significant financial pressure.

The cost-shifting provisions apply to recoverable costs under Code of Civil Procedure Section 1033.5, but critically, Section 998(c)(1) extends to expert witness fees that would otherwise not be recoverable. In a serious catastrophic injury case, expert costs can easily exceed $50,000.00 (Fifty Thousand Dollars), making the statutory penalty substantial. This is why Section 998 offers are referred to as pressure tools: they transform the litigation calculus by adding a layer of financial risk independent of the merits.

Strategic Use by Plaintiffs in Personal Injury Litigation

Plaintiffs use Section 998 offers to create downside risk for defense counsel and insurance carriers who refuse reasonable settlement demands. The typical scenario involves a liability carrier offering an inadequate amount early in litigation, forcing the plaintiff to incur significant expert costs for medical causation, economic damages, and vocational rehabilitation. Once those experts are retained and their fees mount, plaintiff's counsel serves a CCP 998 offer california at a figure slightly below the anticipated trial verdict.

If the defense rejects the offer and the plaintiff obtains a verdict exceeding the 998 amount, the defendant becomes liable for all post-offer expert witness fees under Section 998(c)(1). This can add $30,000.00 (Thirty Thousand Dollars) to $100,000.00 (One Hundred Thousand Dollars) or more to the defendant's exposure depending on the complexity of the case. The threat of this additional liability often motivates carriers to reevaluate their settlement authority and tender policy limits.

Timing is critical. A plaintiff's 998 offer served too early, before the defense has a realistic assessment of exposure, may be ignored. Served too late, it loses strategic value. The optimal window is usually after key depositions are complete, medical records are exchanged, and expert disclosures are made, but with sufficient time before trial for the defense to seek additional settlement authority from the carrier. In auto accident cases involving policy limits disputes, a well-timed 998 offer can also create bad faith exposure under Comunale v. Traders & General Insurance Co., 50 Cal.2d 654 (1958), by demonstrating the carrier's unreasonable refusal to settle within limits.

Defense Use and the Risk to Plaintiffs

Defense counsel also wield Section 998 offers, though the strategic calculus differs. A defendant's 998 offer protects against runaway jury verdicts by capping the defendant's cost exposure if the plaintiff fails to beat the offer at trial. Under Section 998(c)(1), if the plaintiff rejects a defense offer and then recovers less at trial, the defendant can recover post-offer costs, including expert fees.

For plaintiffs, this creates real risk. Rejecting a $150,000.00 (One Hundred Fifty Thousand Dollars) defense 998 offer and then recovering only $100,000.00 (One Hundred Thousand Dollars) at trial means the plaintiff may owe the defense $20,000.00 (Twenty Thousand Dollars) to $50,000.00 (Fifty Thousand Dollars) in expert costs, potentially wiping out a significant portion of the net recovery after attorney's fees and medical liens. This is why plaintiff's counsel must carefully evaluate the risk-reward profile of proceeding to trial when a defense 998 offer is on the table.

Defense 998 offers are particularly effective in cases with disputed liability or comparative negligence issues. If the plaintiff bears 40% comparative fault under CACI 405, a $100,000.00 (One Hundred Thousand Dollars) gross verdict becomes a $60,000.00 (Sixty Thousand Dollars) net award. A defendant's 998 offer of $75,000.00 (Seventy-Five Thousand Dollars) suddenly looks favorable in hindsight, and the plaintiff may face cost-shifting liability.

Statutory Requirements and Common Pitfalls

A CCP 998 offer california must comply with specific statutory formalities to be enforceable. The offer must be in writing, served at least ten days before trial commences, and include clear language allowing acceptance within thirty days. It must be unconditional and not contingent on events outside the offeree's control. An offer that requires the plaintiff to dismiss unrelated parties or waive claims not at issue in the case may be deemed conditional and unenforceable.

Common pitfalls include ambiguous language regarding what claims are being settled, failure to account for costs already accrued, and improper allocation in multi-party cases. In cases with multiple defendants, a plaintiff must serve separate 998 offers on each defendant with clear allocation of the settlement amount. An offer that lumps defendants together without allocation may be unenforceable under Stilwell v. Trutanich, 178 Cal.App.4th 240 (2009).

Another frequent error involves the timing of costs. Section 998 applies only to post-offer costs. If a plaintiff makes an offer on the eve of trial after all expert depositions are complete, the cost-shifting penalty may be minimal because few additional expert fees are incurred. Strategic 998 offers should be served early enough that substantial expert costs remain to be incurred, maximizing the statutory penalty and settlement pressure.

Judicial Discretion and the Interest Component

In addition to cost-shifting, Section 998(e) addresses prejudgment interest. If a plaintiff's offer is rejected and the plaintiff recovers more at trial, the court has discretion to award prejudgment interest on the entire judgment from the date of the offer, rather than from the date of injury or filing. This can significantly increase the defendant's total exposure in cases that take years to resolve.

Conversely, under Section 998(d), if a defendant's offer is rejected and the plaintiff fails to obtain a more favorable judgment, the court may deny the plaintiff any prejudgment interest from the date of the offer forward. This dual interest penalty adds another dimension to the 998 calculus. In a wrongful death case with $1,000,000.00 (One Million Dollars) in damages that takes three years to try, prejudgment interest at 10% can add $300,000.00 (Three Hundred Thousand Dollars) to the judgment, making the timing of 998 offers critical.

Courts exercise discretion in awarding prejudgment interest under Section 998(e), and the decision is fact-specific. A plaintiff who makes a reasonable 998 offer and the defendant rejects it based on a low-ball valuation will likely see prejudgment interest awarded. A plaintiff who makes an inflated 998 offer designed solely to trigger cost-shifting may not receive the same consideration. The key is reasonableness in light of the evidence and the ultimate verdict.

Frequently Asked Questions

What happens if I reject a CCP 998 offer and lose at trial?

If you reject a defendant's CCP 998 offer and recover less than the offer amount at trial, you may be liable for the defendant's post-offer costs under Code of Civil Procedure Section 998(c)(1), including expert witness fees. This can significantly reduce your net recovery after attorney's fees and liens. Your lawyer must carefully evaluate any 998 offer against the risk of an adverse verdict.

Can a CCP 998 offer california include attorney's fees?

Yes, but only if attorney's fees are otherwise recoverable under a statute or contract. Section 998 does not independently create a right to attorney's fees. If your case involves a fee-shifting statute, such as a consumer protection claim, the 998 offer can include attorney's fees incurred to the date of the offer, and the cost-shifting penalties apply to post-offer fees as well.

How long do I have to accept a CCP 998 offer?

You have thirty days from the date of service to accept a CCP 998 offer. If you do not accept within that window, the offer is deemed withdrawn under Section 998(b)(2). Once withdrawn, the cost-shifting consequences remain in effect if the case proceeds to trial. You cannot revive an expired 998 offer without the offeror's consent.

Can I make a CCP 998 offer california after the trial has started?

No. Section 998(b)(2) requires that the offer be made at least ten days before trial commences. An offer served after trial begins is ineffective for cost-shifting purposes. Strategic timing is essential: the offer must be made early enough to allow the opposing party to evaluate it and seek additional settlement authority if necessary.

Does CCP 998 apply to arbitration or only to court trials?

Section 998 applies to any contested proceeding where a judgment or award is entered, including arbitration. If your case is subject to mandatory arbitration under Code of Civil Procedure Section 1141.10, a 998 offer can still trigger cost-shifting based on the arbitrator's award. The same principles apply: if you beat your own offer or the opposing party fails to beat theirs, the statutory penalties are in effect.
