California Business and Professions Code section 6147 requires that every contingency fee agreement between an attorney and a client be in writing and include specific content. An agreement that fails to meet those requirements is voidable at the client's option. The consequence is not just fee reduction; the client can void the agreement entirely, leaving the attorney with a quantum-meruit claim that frequently yields less than the contingency fee would have. For a high-volume PI firm processing hundreds of new matters a year, a form agreement that consistently omits a required element is a systematic exposure that can be triggered whenever a settlement goes sideways.
What Section 6147 Requires
The statute mandates that a written contingency fee contract between attorney and client must include:
- The contingency fee rate that will be charged, including whether the percentage changes at different stages of the case, such as before and after filing a complaint, before and after a trial date is set, and before and after trial commences.
- An explanation of the work the attorney will perform.
- A statement of how litigation costs and expenses will be paid: whether they will be advanced by the attorney, deducted from the recovery before or after the fee is calculated, and who bears them if there is no recovery.
- A statement that the fee is not set by law but is negotiable between attorney and client.
- A statement describing what will happen with any liens against the settlement proceeds.
The agreement must be signed by both the attorney and the client before legal services begin, or as soon as practicable after the attorney-client relationship commences in circumstances where immediate services are required. A fee agreement signed after the case is already substantially worked up is still better than no agreement, but it creates an argument that the pre-signature services were provided without a compliant contract.
Common Compliance Failures
High-volume plaintiff firms most commonly fail section 6147 compliance in the following ways:
- Static fee percentages without stage disclosure. A form agreement that states a flat 33.33% contingency without specifying whether that percentage applies at all case stages, or identifying a higher percentage if the case proceeds to trial, does not fully comply. Many California PI fee agreements use a tiered structure (33% if settled pre-litigation, 40% if litigation is filed, sometimes higher if trial begins). All of those tiers must be disclosed in the written agreement.
- Inadequate costs language. The agreement must specify how costs and litigation expenses are handled. Vague language such as "client is responsible for costs" does not satisfy the statute. The agreement should state whether costs are advanced by the attorney, whether they are deducted from the gross settlement before the contingency fee is calculated or from the net after, and what happens to advanced costs if the case is lost.
- Missing lien disclosure. The requirement to describe what will happen with liens is frequently omitted from template agreements. The statute requires at minimum a statement that liens may exist against the settlement and a description of the general process for addressing them. In practice, a more detailed lien disclosure protects the firm from later disputes with clients who claim they did not understand that a medical provider or workers' comp carrier would be paid from the settlement.
- Not updating for appeal. Section 6147 applies to appeals as well. If the case proceeds to appeal and the fee arrangement changes, a new or amended written agreement is required. Many firms forget this and rely on the original agreement.
Referral Fee Compliance Under Rule 1.5.1
California Rules of Professional Conduct Rule 1.5.1 requires that any division of fees between attorneys in different firms be disclosed to the client in writing and consented to by the client. The client must be advised that a referral fee is being paid, even if the division does not increase the client's overall fee. This is a separate requirement from section 6147 and is frequently handled informally, creating exposure when referral arrangements later become disputed.
The referral fee disclosure should be part of the fee agreement itself, naming the referring attorney or firm and the terms of the division. If the division is uncertain at the time of signing, the agreement should describe the structure and how it will be determined, with a requirement to notify the client when the actual division is established. Some firms use a separate letter to the client confirming the referral arrangement; either approach is acceptable so long as the client's written consent is obtained and retained in the file.
The Intake Process as the Compliance Gate
Fee agreement compliance is fundamentally an intake process issue. The intake coordinator or intake attorney should be responsible for ensuring that the compliant fee agreement is signed before any substantive legal work is done on the file. A matter should not advance from intake to active case status in the case management system without a verified signed fee agreement in the client file.
Some firms use electronic signature platforms, which are compliant with California law so long as the agreement itself contains all required section 6147 elements, the electronic signature system captures a verifiable consent record, and a copy is provided to the client. The copy-delivery obligation is not discretionary; section 6147 requires that the client receive a signed copy of the agreement.
Periodic audits of active case files against the fee agreement compliance checklist are a low-cost risk management practice. Audit for: signed agreement in the file, appropriate tier disclosure, costs language, lien disclosure, and referral fee consent where applicable.
