What varies by jurisdiction

In California, the Offer Of Judgment Analyzer in DocketMath is primarily anchored to Cal. Code Civ. Proc. § 998 (“§ 998”). The main “variation” you should account for is not that DocketMath becomes a different calculator within California—it’s that the timing rules and the legal effect tied to offers can change based on (a) the statutory timing window and (b) the procedural milestone you use (trial vs. arbitration).

For California specifically, treat § 998 as your default framework, then verify whether your case involves arbitration or any procedural posture that changes which milestone matters.

California baseline: the general (default) offer timing

California’s statute includes a default lead-time requirement for when an offer may be served for purposes of the offer-based mechanisms. The key timing language is:

“Not less than 10 days prior to commencement of trial or arbitration … any party may serve an offer in writing upon any other party … to allow judgment to be taken or an award to be entered in accordance with the terms and conditions stated…”

Important note: The brief for this page indicates that no claim-type-specific sub-rule was found for the 10-day timing period in the provided statute excerpt. So, use the 10-day rule as the general/default period for California unless you have a separate, case-specific basis to model a different timeline (for example, if your situation involves arbitration procedural milestones that still fall under the statute’s “commencement” framing).

What this means inside DocketMath (US-CA)

When you run the Offer Of Judgment Analyzer for US-CA, your results are sensitive to inputs that determine whether the offer is within the statutory window and whether the analyzer is comparing the correct “judgment” value. In practical terms, the output can change if any of these inputs are off:

Offer date / service date (what matters for the “served not less than 10 days prior” check)
Trial date or the relevant arbitration commencement date
Whether the tool is being used to model a § 998 offer (the tool name/prompting matters)
Offered amount
The judgment after trial (or equivalent benchmark) you’re comparing against

Because § 998 is procedural, the model’s “timely vs. not timely” logic typically depends on your dates and the milestones you tell it about.

The timing text (anchor for the rules engine)

From Cal. Code Civ. Proc. § 998 (timing anchor):

“Not less than 10 days prior to commencement of trial or arbitration … any party may serve an offer in writing upon any other party…”

This sentence is the core for California’s default rule in DocketMath: the offer must be served at least 10 days before the commencement of the relevant proceeding.

Jurisdictional variation points you should expect (even across projects)

Even if the same DocketMath product runs in multiple jurisdictions, the “variation” typically shows up in a few reusable places:

Variation point	Why it changes results	California anchor
Minimum lead time before trial/arbitration	Determines whether the offer-triggered outcomes can apply	10 days prior to commencement
Whether the milestone is trial vs. arbitration	Changes which date is used for compliance checks	Statute uses “trial or arbitration”
Procedural posture and date definitions	The tool must map your provided dates to “commencement”	Uses “commencement” (not “hearing”)
Offer structure/wording effects	Some outcomes depend on whether the offer is properly made in writing with terms that allow judgment/award	Requires “in writing” and terms allowing judgment/award

To keep analysis consistent, remember: within California, the statute’s default timing is your baseline; the biggest practical “variation” is often simply which commencement date you enter and how.

What to verify

Before you rely on a DocketMath Offer Of Judgment Analyzer output for US-CA, verify these items. This is not legal advice—it’s a practical checklist to reduce avoidable modeling errors.

1) Confirm the “not less than 10 days prior” timing using your real dates

The analyzer needs to know whether the offer was served at least 10 days before the relevant commencement date.

Verify:

What date the offer was actually served (not just drafted)
What date your case record treats as trial commencement (or arbitration commencement)
Whether the service-to-commencement gap meets “not less than 10 days prior” under Cal. Code Civ. Proc. § 998

Common pitfall: entering a signature date or mail date when the tool logic (or your case records) rely on the service date. If the wrong “offer date” is used, the tool may flip the result between “timely” and “not timely.”

2) Use the correct milestone: trial vs. arbitration

California’s timing sentence applies to both:

“trial”
“arbitration”

So verify:

If arbitration applies, you provided the arbitration commencement date (not merely a hearing date)
If the matter shifted between arbitration and trial, you reflected the correct procedural milestone for the analysis you want

3) Ensure the tool run matches § 998 (the mechanism you’re modeling)

Make sure your DocketMath inputs/settings match the mechanism:

Jurisdiction set to US-CA
Offer type/prompt corresponds to § 998
You input an offer amount that the analyzer can compare to the judgment benchmark

4) Verify the “judgment after trial” benchmark being used

The analyzer usually compares your offer amount against a judgment after trial figure (or similar court-awarded amount). Before you trust the comparison:

Confirm what the tool considers the “judgment” number (e.g., does it include all awarded components you intended?)
If your judgment has multiple components, ensure you’re entering the correct total consistent with how the tool defines the benchmark

If you’re unsure how the tool expects this value, review the tool’s input prompts/help text before rerunning.

5) Check the offer basics the statute excerpt implies (writing + terms)

The statute excerpt emphasizes the offer must be “in writing” and must allow “judgment to be taken or an award to be entered” according to the offer’s terms.
