How to run attorney fee calculations in DocketMath for California

Step-by-step

This walkthrough shows how to run attorney fee calculations in DocketMath for California (US-CA) using the Attorney fee calculator.

1) Open the right tool and set jurisdiction

1. Go to /tools/attorney-fee.
2. Confirm the calculator is set to California (US-CA).
3. Select the claim type that matches what you’re calculating, because California fee limitations and fee-shifting concepts aren’t identical across different claim types.

2) Choose the fee framework (what DocketMath should model)

DocketMath’s output depends on which fee framework you select for your scenario. Use the framework that matches how you expect the fee to be calculated:

• Contingency fee models: Use when you’re computing a percentage-based contingent fee and want the result checked against California’s contingency fee rules.
• Fee-shifting / statutory attorney’s fee models: Use when your scenario is structured to award attorney’s fees to a prevailing party under fee-shifting provisions, such as 42 U.S.C. § 1988(b), 29 U.S.C. § 216(b), or California provisions like Cal. Civ. Proc. Code § 1021.5.

3) Enter the contingency fee parameters (if applicable)

If you’re calculating a contingency fee, enter the inputs DocketMath requests so it can apply the relevant percentage cap based on settlement timing and whether the matter is medical malpractice.

For medical malpractice, contingency fee limits are governed by Cal. Bus. & Prof. Code § 6146(a) (MICRA, as amended by AB-35 effective 2023). In that medical malpractice category:

• 25% applies if settled before civil complaint or arbitration demand is filed (Cal. Bus. & Prof. Code § 6146(a)).
• 33% applies if settled after filing (Cal. Bus. & Prof. Code § 6146(a)).
• The court may approve a higher fee for good cause after trial/arbitration (Cal. Bus. & Prof. Code § 6146(a)).

DocketMath’s contingency-cap logic reflects the medical-malpractice safe facts:

• Medical malpractice pre-filing max percentage: 25
• Medical malpractice max percentage: 33

Also, keep the ethics overlay in mind: Cal. Rules of Prof. Conduct 1.5 addresses reasonableness and factors related to attorney fees. DocketMath is a calculation tool—your workflow should still align with a reasonableness/ethics review even if the numbers fit inside a cap.

4) Enter lodestar-based parameters (if applicable)

If your workflow includes a lodestar multiplier, DocketMath can apply multiplier constraints using these safe facts:

• Default multiplier cap multiplier: 1
• Maximum multiplier cap multiplier: 4

To run this accurately in DocketMath:

1. Provide the lodestar components the calculator requests (use the tool’s field labels).
2. Provide the multiplier (if prompted).
3. Confirm the multiplier is consistent with the calculator’s cap logic so you don’t unintentionally exceed what the model will allow.

5) Select the fee-shifting statute path (when you’re not modeling contingency caps)

If you’re modeling statutory fee awards rather than contingency fees, choose the claim type/framework in DocketMath so it uses the correct fee-authorizing concept.

Examples of fee authorities you may see mapped into DocketMath claim types include:

• Federal fee-shifting

  • 42 U.S.C. § 1988(b)
  • 29 U.S.C. § 216(b)
  • 42 U.S.C. § 2000e-5(k)
  • 42 U.S.C. § 12205
• California statutory fee authority

  • Cal. Civ. Proc. Code § 1021.5
  • Cal. Civ. Code § 1780(e)
  • Cal. Civ. Code § 1794(d)
  • Cal. Civ. Proc. Code § 425.16(c)(1)

6) Confirm limitation/receipts logic in the calculator

Some DocketMath workflows use receipts inputs and apply a limitation period concept. Your verified configuration indicates:

• receipts.0.limitation_period: see statute
• receipts.1.limitation_period: see statute

To use this correctly:

• Only enter receipts data when the calculator indicates it’s relevant to the framework you selected.
• Keep the receipts inputs aligned with the claim/stats path you chose in the tool so the limitation logic matches the intended scenario.

7) Review outputs and sanity-check them against the cap logic

After you run the calculation, sanity-check the result based on the framework you selected:

• If you used a medical malpractice contingency model: confirm the output reflects 25% (pre-filing) or 33% (after filing) under Cal. Bus. & Prof. Code § 6146(a).
• If you used a lodestar multiplier: confirm the multiplier behavior is consistent with the tool’s cap configuration (max multiplier 4).
• If you used a statutory fee framework: review which framework drove the result (contingency vs fee-shifting logic).

Even when the calculation fits inside a cap or expected formula, remember DocketMath is not a substitute for ethics or legal judgment under Cal. Rules of Prof. Conduct 1.5.

Quick reference table (what changes outputs)

Common pitfalls

• Wrong fee framework selected

  • Example: using contingency inputs when the scenario should be run under a statutory fee-shifting framework (or vice versa).
• Medical malpractice timing not represented

  • If settlement occurs after filing, the medical-malpractice cap reflects the 33% category under Cal. Bus. & Prof. Code § 6146(a); before filing aligns with 25%.
• Lodestar multiplier entered above the tool’s allowed range

  • DocketMath’s multiplier cap configuration limits how high the model will allow the multiplier to go (max 4).
• Receipts fields filled when the claim type/framework doesn’t use them

  • Receipts logic uses limitation-period handling (“see statute”). If you choose an unrelated framework, the result may not match what you intended to model.

Try it

1. Open /tools/attorney-fee.
2. Pick California (US-CA).
3. Use this checklist while entering inputs:

• Claim type/framework matches your intended theory (contingency vs fee-shifting/statutory)
• If running medical malpractice contingency: settlement timing is reflected so you get the right 25% vs 33% behavior under Cal. Bus. & Prof. Code § 6146(a)
• If using lodestar: multiplier stays within the tool’s configured cap (max 4)
• Receipts section inputs are only completed when relevant, and aligned with the claim/stats path

1. Run the calculation and review:

• Which framework drove the result (contingency vs statutory/fee-shifting vs lodestar logic)
• Whether any amounts appear “capped” by the model logic
• The final figure produced by that specific framework
