CCP 998 Form Explained: Strategic Use

You reject a settlement offer because the verdict appears likely to exceed it. Trial arrives, the jury awards less than the offer, and the other side seeks post-offer costs that were invisible during ordinary negotiations. Under California’s statutory offer-to-compromise procedure, a case can produce a favorable-looking judgment and still leave the rejecting party with a damaging net result.

That’s why the CCP 998 form, officially Judicial Council Form CIV-090, deserves more attention than a standard settlement letter. Section 998 can change the financial consequences of litigation, especially after a rejected offer and a later pre-trial settlement.

Why the CCP 998 Form Matters in California Civil Cases

Consider a plaintiff who rejects a $150,000 CCP 998 offer, proceeds to trial, and receives a $120,000 judgment. The plaintiff technically wins, but the result may trigger exposure to the defendant’s post-offer costs, including potentially significant expert witness expenses. The judgment can look like a victory on paper while producing a much smaller recovery after cost consequences.

That financial pressure is the point of California Code of Civil Procedure section 998. Enacted in 1971 as a statutory offer-of-compromise mechanism, the statute expanded an earlier rule that applied only to defendant offers. It later became a two-way cost-shifting tool that either side can use, and an offer not accepted within 30 days is deemed withdrawn. The history and statutory development are discussed in the California Supreme Court’s opinion in T.M. Cobb Co. v. Superior Court.

More than a settlement letter

A conventional settlement demand expresses a willingness to resolve a dispute. A 998 offer does more. It creates a statutory decision point that can affect the parties’ later entitlement to costs if the offeree fails to obtain a more favorable judgment.

The official form, CIV-090, is titled “Offer to Compromise and Acceptance Under Code of Civil Procedure Section 998.” The form explains the central consequence plainly: if the offer isn’t accepted and the rejecting party doesn’t do better at trial, post-offer costs may shift. The Judicial Council’s CIV-090 form is optional, however, and it’s designed for civil actions involving a single plaintiff, a single defendant, and a money judgment.

Practical rule: Treat every 998 offer as a litigation-risk instrument, not as ordinary negotiation correspondence.

The statute serves several related purposes. It encourages parties to settle before trial, penalizes litigation positions that ultimately prove unreasonable, and reallocates certain financial risks to the party that rejected a reasonable resolution. A civil litigation attorney evaluating discovery, expert needs, damages, insurance, and trial uncertainty must account for those risks alongside the apparent settlement value. For background on that broader role, see what a civil litigation attorney does.

Plaintiffs and defendants can both make offers, but their incentives aren’t identical. A defendant often uses a 998 offer to place a ceiling on practical exposure and shift later costs if the plaintiff underperforms. A plaintiff may use one to pressure a defendant that rejects a reasonable demand and then faces a less favorable judgment. In either direction, the offer changes the question from “What is this case worth?” to “What result must I obtain to avoid a financial penalty?”

How the CCP 998 Offer to Compromise Works

Section 998 permits any party in a California civil action to serve a written offer allowing judgment to be taken, or an award to be entered, on stated terms. The offer can come from a plaintiff or defendant, but the document must give the opposing party enough information to understand exactly what resolution is being proposed.

The document must create a usable decision

A sound CCP 998 form or custom offer should identify the proposed judgment or award and its terms and conditions. It should also include a clear method for acceptance by signed writing. The recipient needs to know what will happen if the offer is accepted, including whether the proposed resolution includes costs, releases, dismissal provisions, or other terms affecting the case.

The Judicial Council’s CIV-090 provides a standardized format, but it isn’t the only possible document. A custom-drafted offer may work if it satisfies the statutory requirements. The form is therefore useful for organization and clarity, but using it doesn’t automatically cure an unclear term, defective service, improper signature, or multi-party allocation problem.

The official form has a narrower operational purpose than many users assume. It’s intended for a single plaintiff, a single defendant, and a money judgment. The court files the offer and acceptance when they’re accompanied by a judgment prepared for the court’s signature, making CIV-090 closely tied to entry of judgment rather than functioning as a standalone settlement memorandum.

Acceptance, rejection, and silence

The offeree accepts by signing the acceptance and completing the required filing process before the statutory deadline. The California Courts self-help materials for CIV-090 identify the form as an optional Judicial Council form and reinforce the importance of using the required written acceptance procedure.

If the offeree accepts properly, the court can enter judgment according to the stated terms. If the offer is rejected, ignored, or expires, the case generally proceeds. The offer ordinarily isn’t presented to the judge or jury as evidence of liability or damages during trial, but it remains important for later cost proceedings.

The cost-shifting mechanism becomes relevant when the offering party obtains a more favorable judgment and the offeree hasn’t achieved the required result. Depending on the direction of the offer and the applicable findings, the consequences can include loss of otherwise recoverable post-offer costs and liability for the other side’s qualifying post-offer costs, including expert witness fees. The California statutory text for section 998 states that a written offer must be served at least 10 days before trial begins, or before the start of a covered arbitration.

The practical lesson is simple. Draft the offer so a court can determine what was offered, whether it was accepted, whether the acceptance was timely, and whether the eventual result was more favorable.

Critical Deadlines and Timing Rules

Section 998 timing is unforgiving because several rules operate at once. An offer can be served at any point in the litigation, but it must be served at least 10 days before trial or arbitration begins under the statutory rule described in California Code of Civil Procedure section 998. An offer relating to a legal issue may also be governed by timing tied to the relevant hearing.

Once served, the offeree generally has 30 days, or until trial or arbitration begins, whichever occurs first, to accept. The offer isn’t open indefinitely. Under the procedural explanation provided by California litigation counsel discussing section 998 expiration, an unaccepted offer is deemed withdrawn after that period or at the earlier commencement of trial or arbitration.

The calendar matters

A late acceptance generally doesn’t revive the original offer. Instead, it may be treated as a new offer from the original offeree, leaving the other side free to accept or reject it. Counsel should calculate the response deadline from the actual service date, identify the first day of trial or arbitration, and use the earlier event as the controlling endpoint.

Continuances create another practical problem. A reset trial date may affect whether an offer satisfies the minimum pre-trial service period, but it doesn’t erase the importance of the original service, response, and expiration analysis. Counsel shouldn’t assume that moving trial automatically renews an expired offer or reopens an acceptance period.

Service before a lawsuit is filed presents a separate concern. Section 998 operates within a civil action, so a proposed offer made before filing shouldn’t be treated casually as a statutory offer. Once litigation begins, the offer must still meet the written-content and service requirements.

If the thirtieth day falls on a weekend or court holiday, deadline calculations require care under the applicable procedural rules and service method. The safest practice is to calculate conservatively, confirm the governing extension rules, and avoid relying on a last-day acceptance when the validity of the offer matters.

Strategic Considerations for Plaintiffs and Defendants

The same statute creates different pressures depending on who serves the offer. A defendant’s offer can force a plaintiff to evaluate whether the expected judgment will exceed the offer enough to justify continued litigation and the risk of post-offer costs. A plaintiff’s offer can put pressure on a defendant that rejects the demand and later receives a less favorable result.

The two sides are not making the same bet

For plaintiffs, the central question is whether the offer accurately reflects a defensible valuation of the claim. A plaintiff’s offer that’s too aggressive may be easier to reject and harder to enforce. A well-supported offer can create an advantage, but it also places the plaintiff’s valuation under scrutiny if the case reaches judgment.

Defendants usually focus on exposure control. A carefully timed offer can frame the plaintiff’s expected recovery and shift the financial consequences of an unsuccessful trial decision. But an offer that ignores clear liability, established damages, or the cost of necessary experts may look performative rather than reasonable.

Factor	Plaintiff’s 998 Offer	Defendant’s 998 Offer
Primary objective	Create settlement pressure and preserve potential cost advantages	Limit practical exposure and shift post-offer risk
Main evaluation	Whether the demand fits the provable value of the claim	Whether the offer gives the plaintiff a meaningful reason to settle
Principal danger	Setting an amount that can’t be justified by the evidence	Making an offer so low that it won’t support a credible cost motion
Multi-party concern	Allocating responsibility and acceptance terms clearly	Avoiding ambiguity about which defendant offers what relief
Insurance impact	Policy limits may constrain the realistic settlement target	Coverage disputes may limit authority or make an offer difficult to fund

A multi-defendant case adds another layer. If several defendants participate, the parties must address whether the offer is joint, several, apportioned, or conditioned on particular dismissals. Without clear allocation, comparing the eventual judgment with the offer can become a dispute of its own.

Insurance also changes the practical calculus. Policy limits, reservation-of-rights positions, additional-insured issues, and coverage disputes may determine whether an offer can be accepted. A settlement figure that looks strategically attractive may be impossible to implement unless the insurer, insured, and counsel understand who will fund the judgment and what claims will be released.

For clients weighing settlement against trial, this guide to choosing between settlement and trial in a personal injury case provides broader context. A 998 decision should be part of that analysis, not a substitute for it.

Hidden Cost-Shifting Traps After the Madrigal Decision

A rejected CCP 998 offer can remain financially important after the parties appear to have settled. As discussed in a 2025 analysis by Inside Class Actions, the California Supreme Court’s decision in Madrigal v. Hyundai Motor America interpreted section 998’s cost-shifting rule as applying when a case resolves through a later pre-trial settlement after rejection of a valid offer. The San Francisco Superior Court’s section 998 materials also show why acceptance and judgment procedures must be handled carefully.

The risk commonly develops in stages. A plaintiff rejects a defendant’s valid offer. The parties later negotiate a separate settlement with terms less favorable than the rejected offer. They sign the agreement, dismiss the case, and treat the dispute as finished. The defendant then contends that the earlier offer still limits the plaintiff’s recovery of litigation costs, even though no trial verdict was entered.

Settlement doesn’t automatically erase the offer

Settlement agreements often address payment, dismissal, releases, liens, confidentiality, and enforcement. They may say nothing about whether either party waives section 998 consequences. That gap can produce a later dispute over costs, expert fees, and whether the final resolution was more favorable than the rejected offer.

Before signing a later settlement, counsel should audit every outstanding 998 offer. Review the offer date, terms, service record, acceptance deadline, relationship to the trial date, and the proposed settlement’s value after relevant costs and obligations are considered. Compare the offer with the probable range of possible judgments, not just the headline settlement amount.

Settlement safeguard: If the parties intend to resolve all cost issues, the written agreement should address the rejected 998 offer expressly rather than assuming the settlement supersedes it.

The agreement should identify who bears post-offer costs, whether the parties waive or reserve a section 998 motion, and whether the settlement resolves cost and fee claims separately from damages. Those provisions must fit the procedural posture. A general release may not clearly resolve a specific statutory cost dispute.

The Madrigal analysis also affects mediation planning. Switching from a formal offer to a mediated settlement does not by itself make the original offer irrelevant. Counsel should ask whether the later resolution leaves the rejecting party in a less favorable position than the earlier statutory offer.

Evaluate exposure on a net basis. Expert expenses, recoverable litigation costs, and settlement-enforcement language can materially change the result. Post-settlement cost motions are often supported through a memorandum of costs, so preserve the offer, service, settlement, and cost records before the case is closed.

Common Formality Mistakes That Invalidate a 998 Offer

A 998 offer can have strong economics and still fail because the document or service record is defective. The official form reduces drafting uncertainty, but it doesn’t eliminate the need to verify the parties, terms, signatures, service, and acceptance procedure.

Drafting and signature problems

The offer should be unmistakably identified as a statutory offer under section 998. It should state definite judgment or award terms and explain how the offeree may accept by signed writing. Ambiguous language creates a later comparison problem because the court may be unable to determine what result would have counted as more favorable.

Common errors include:

• Unclear settlement terms: The document doesn’t specify the amount, judgment language, cost treatment, dismissal obligations, or other material conditions.
• Missing acceptance mechanism: The offer lacks a clear statement that the offeree may accept by signing and returning the acceptance.
• Improper signature: The party or authorized attorney hasn’t signed the offer or acceptance in the manner required by the statute and applicable rules.
• Defective service: Counsel can’t prove when and how the offer was served, or service occurred too close to trial.
• Multi-party ambiguity: A joint offer doesn’t identify each offeree’s obligations, allocation, or the consequences of accepting separately.

The form’s optional status matters here. CIV-090 may be safer as a starting point, but it isn’t automatically valid for mixed claims, multiple plaintiffs, multiple defendants, or non-monetary terms outside its intended design. A custom draft may be more appropriate when the case requires allocation or detailed performance obligations.

Service and acceptance deserve separate review

Electronic service, mail, and personal delivery can raise different deadline questions. The offer’s service method should be authorized, documented, and analyzed for any applicable time adjustment. A proof of service should identify the recipient, method, date, and address or electronic destination used.

The acceptance record needs the same discipline. Confirm that the correct party accepted, the signature is authorized, the acceptance was written, and the filing occurred before the applicable deadline. Counsel shouldn’t assume that a signed email, informal response, or later settlement document automatically satisfies the statutory acceptance procedure.

The 2022 amendments to section 998 changed signature and acceptance requirements, so lawyers should use the current statute and current forms rather than rely on older templates. Technical compliance isn’t clerical housekeeping. It determines whether the offer can support the cost-shifting result that justified making it.

Key Takeaways and Next Steps for Your Case

The CCP 998 form is a strategic device with financial consequences, not a routine settlement attachment. Before sending or responding, evaluate the offer against the likely judgment, the evidentiary record, the remaining expert work, insurance constraints, and the client’s ability to tolerate an adverse cost result.

Use this decision checklist:

1. Confirm the posture: Make sure a civil action exists and determine whether the offer is suitable for CIV-090 or requires a custom draft.
2. Test the valuation: Compare the offer with the realistic range of possible judgments, not the client’s best-case expectation.
3. Check the calendar: Verify the 30-day acceptance period and the requirement that service occur at least 10 days before trial or arbitration, using the governing procedural sources linked above.
4. Audit the language: Review the judgment terms, conditions, acceptance provision, signatures, and treatment of costs.
5. Analyze the settlement path: If a rejected offer remains outstanding, address it expressly in any later settlement, particularly after Madrigal.
6. Preserve the record: Keep the offer, proof of service, acceptance or rejection, trial-date notices, settlement agreement, and cost documentation together.

A plaintiff deciding whether to reject should calculate the likely net recovery, not just the anticipated verdict. A defendant deciding whether to send an offer should consider whether the amount and terms give the plaintiff a meaningful reason to accept and can withstand a later good-faith challenge. In multi-party litigation, allocation must be clear enough for the court to compare the offer with the eventual result.

Timing and technical compliance are essential. A missed deadline, vague condition, defective signature, or incomplete service record can eliminate the intended protection. Before deploying or responding to a CCP 998 offer, consult qualified California litigation counsel about the specific facts, claims, parties, and coverage issues in your case.
