Referral fees between lawyers are governed by the rules of professional conduct in the jurisdiction where the matter is handled. Most states model their rule on ABA Model Rule 1.5(e), which sets three conditions for dividing a fee with a lawyer outside your firm.
The three conditions under Model Rule 1.5(e)
- Condition 1
Proportional services or joint responsibility
The division must be in proportion to the services each lawyer performs, or each lawyer must assume joint responsibility for the representation. This is the requirement that varies most between states.
- Condition 2
Written client agreement
The client must agree to the arrangement, including the share each lawyer will receive, and that agreement must be confirmed in writing.
- Condition 3
A reasonable total fee
The overall fee charged to the client must still be reasonable. A split cannot be used to inflate what the client pays.
Paying a non-lawyer is a different rule
Model Rule 5.4(a) prohibits sharing legal fees with non-lawyers, and Model Rule 7.2 restricts giving anything of value to a person for recommending your services, with narrow exceptions such as reasonable advertising costs and legitimate lawyer referral services. So the analysis for "can I pay another firm for this case" and "can I pay a marketer per signed client" are not the same question, and the second one is where firms most often get into trouble.
How the fee itself is usually structured
Once the arrangement is permissible, the number comes from one of three structures: a flat amount agreed up front, a straight percentage of the total attorney fee, or tiered percentages where each rate applies only to the portion of the fee inside its band. Percentage splits are the most common in contingency work. You can run all three on the same fee in our attorney referral fee calculator.
Document it, then track it
Two records matter: the client's written agreement to the division, and the lawyer-to-lawyer terms. Our referral agreement template covers the second. After that, the practical problem is knowing where a referral stands months later — which is what Ethix does: a verified referral record, live status the receiving attorney can update without an account, and a documented trail of what was agreed and when.
Common questions
Can attorneys pay referral fees to other attorneys?
Generally yes, subject to the rules of professional conduct in the relevant jurisdiction. ABA Model Rule 1.5(e) permits a division of a fee between lawyers who are not in the same firm when the division is proportional to the services each performs (or each lawyer assumes joint responsibility), the client agrees to the arrangement in writing including the share each lawyer will receive, and the total fee is reasonable. States adopt variations of this rule, so check your own.
Can a lawyer pay a referral fee to a non-lawyer?
No. Model Rule 5.4(a) prohibits sharing legal fees with non-lawyers, which is why paying a marketer, client, or other non-lawyer a cut of the fee is treated very differently from a lawyer-to-lawyer division. Rule 7.2 similarly restricts giving anything of value for a recommendation, with narrow exceptions such as reasonable advertising costs and qualified lawyer referral services.
Does the client have to consent?
Under the Model Rule the client must agree to the arrangement in writing, and the writing must disclose the share each lawyer will receive. Some states go further and require the disclosure to include each lawyer's responsibilities in the matter.
Do both lawyers have to do work on the case?
Under the Model Rule the split must either be proportional to the services performed or the referring lawyer must assume joint responsibility for the representation. A few states are stricter and require actual work or a defined role; a handful are more permissive. This is the provision that varies most by jurisdiction.
Does the referral fee have to be in writing?
The client's agreement must be in writing under the Model Rule, and documenting the lawyer-to-lawyer terms is standard practice even where it is not strictly required. A written agreement records the percentage or flat amount, the basis it is calculated on, and who carries which responsibility.
This page is general information, not legal advice. Rules differ by jurisdiction and change over time — confirm the current rule in your state before agreeing to any fee division.
Documenting the fee division is the part firms get wrong months later. Ethix referral management software keeps the agreed split, client disclosure, and status history on the referral record itself.
