Can California Lawyers Share Referral Fees? Rule 1.5.1 Explained

Updated September 2026. This article is for general informational purposes and is not legal advice.

BLUF: Yes. California lawyers who are not in the same firm may divide a legal fee, including a referral fee, if they comply with California Rule of Professional Conduct 1.5.1. The lawyers must have a written fee-division agreement; the client must give written consent after written disclosure of the participating lawyers and the terms of the division; and the total fee may not be increased solely because the lawyers are dividing it.

For California firms that regularly receive or send referrals, the rule is more than an ethics footnote. It should shape the referral process from the beginning of the case. A clean referral relationship protects the client, protects both firms, and reduces disputes after a case resolves.

What does California Rule 1.5.1 require?

Rule 1.5.1 governs fee divisions between lawyers who are not in the same law firm. In practical terms, there are three core requirements:

1. The lawyers must agree in writing to the fee division.
2. The client must consent in writing. Before that consent, the client must receive written disclosure that a division will be made, the identity of the lawyers or firms participating, and the terms of the division.
3. The total fee cannot be increased solely because of the fee-sharing arrangement.

The State Bar’s rule text should always control. Lawyers should review the current rule before documenting a referral arrangement.

Does the referring lawyer have to perform part of the work?

California’s rule is notably different from fee-division rules in some other jurisdictions. Rule 1.5.1 does not state that the division must be proportional to the services each lawyer performs. That makes California referral arrangements especially important to document correctly: the written agreement and written client consent are not administrative details; they are central to the arrangement.

Out-of-state lawyers should not assume their home jurisdiction’s referral-fee rule works the same way in California. If the matter is being handled in California, counsel should evaluate the California rule as well as any rules applicable in the referring lawyer’s jurisdiction.

When should the client consent to the fee division?

The rule provides that the client’s written consent should be obtained when the lawyers enter into the fee-division agreement or as soon thereafter as reasonably practicable. From a practice-management standpoint, earlier is better. Referral terms should not emerge for the first time at settlement or distribution.

What should the written disclosure tell the client?

The disclosure should clearly identify:

• that a division of fees will occur;
• the lawyers or law firms participating in the division; and
• the terms of the division.

Clarity matters. A client should be able to understand who is involved and how the fee will be allocated without having to infer the arrangement from separate documents.

Can a lawyer receive a referral fee on a contingency case?

Potentially, yes, but the referral arrangement does not replace the requirements that apply to the underlying fee agreement. California contingency-fee agreements have their own statutory requirements, and the lawyers should ensure that the engagement documents and fee-division documents work together.

A practical referral file should therefore include the operative client fee agreement, the written agreement between counsel, and the client’s written consent to the division.

What should referring attorneys ask before sending a case?

The economics matter, but they should not be the only question. On a serious personal-injury case, referring counsel should also ask who will actually litigate the matter, whether the receiving firm has the resources to fund experts and discovery, how often the referring lawyer will receive updates, and whether the case is being prepared for trial from the outset.

Proper Law’s Attorney Referrals practice is built around those concerns. The firm states that it prepares every case as if it will go to trial and keeps referring attorneys informed throughout the matter.
