Signed Retainer Leads: What Personal Injury Firms Should Know Before They Commit

What is a signed retainer lead?

A signed retainer lead is a client the provider's intake team has signed to a retainer agreement with the law firm before handing them over. The provider handles marketing and intake through to signature, and your firm receives a signed client.

It's the third of the three delivery models, after web form leads and live transfers. Anthony Bux described it on Personal Injury Mastermind as the model where "your marketer is now delivering soup to nut, intake, marketing, intake, and signing retainers, passing them over to the law firm." It has gained ground quickly with firms that want to skip the intake work altogether.

How does a signed retainer lead work?

The provider runs every step up to the signature, then hands the signed client to your firm. Your firm's first contact with the client usually comes after they've already agreed to be represented.

1. The injured person responds to an ad. They call or fill in a form on the provider's landing page.
2. The provider's intake team screens them. An agent asks about the accident, the injuries, fault and whether the person already has a lawyer.
3. The agent walks them through your retainer agreement. The client signs your firm's agreement, usually electronically, on that call or soon after.
4. The provider sends the signed client to your firm. You receive the signed agreement, the intake notes and the client's contact details.
5. Your firm takes over. Your team calls the client, introduces the firm, confirms the case details and starts the work.

How do signed retainers compare with web form and live transfer leads?

Signed retainers ask the least of your intake team up front and the most of your client care afterward. Each step up the delivery models costs more, because the provider does more of the work. With signed retainers, you're paying for the signature, so check carefully what you get with it.

Why do signed retainer clients drop?

They drop because a signature doesn't create a relationship. The client signed with a voice on the phone that wasn't your firm, often while they were in pain or stressed, and they may not remember your firm's name the next day. If another firm reaches them first with more warmth, they can leave.

Anthony's advice to firms is to ignore the signature when it comes to follow-up: "You treat that signed case just like a lead. They still need to talk to you guys. You guys still need to discuss the next steps." The client hasn't met your firm yet. Your first call is where that starts.

Drops also come from the provider's side. Weak screening can produce signed clients who don't fit your criteria, and pressure to hit volume can lead to clients who signed without fully understanding what they agreed to.

What should your firm do when a signed retainer arrives?

Call the client fast, on the same day and ideally within the hour, and treat that call as the start of the relationship. Introduce your firm by name, explain who will handle the case and confirm the details from the intake notes without making the client repeat everything.

Then keep the contact going. Set expectations for what happens next, give the client a direct number and check in through the first few weeks. Our guide to keeping third-party clients after signing covers the first 90 days in detail, and the intake playbook for third-party leads covers the handoff.

Your firm also has to do its own work before it relies on the signature: a conflict check, a review of the case and confirmation that the matter is one you'll take.

What are the legal and ethical questions with signed retainers?

Signed retainers raise more questions than other delivery models, because a non-lawyer is signing clients to your firm's agreement on your behalf. State bar rules on paying for recommendations, solicitation by non-lawyers and sharing legal fees all come into play, and they vary from state to state.

Questions to raise with your own counsel include whether the payment structure is allowed in each state you work in, what the provider's agents can and can't say about your firm, and how the arrangement is disclosed to clients. Consent rules also apply to the provider's calls and texts. The federal rule that would have required consent to name each individual company was struck down in early 2025, but the TCPA's existing consent requirements still apply. Have your own counsel confirm what applies to your firm before you start.

What should you check before you sign a signed retainer agreement?

Check how the provider speaks for your firm and what happens when a signed client isn't what you expected. These are the terms that decide whether the model works.

• Traffic source: Whether the provider generates its own traffic or buys it from aggregators.
• Intake script and recordings: What agents say about your firm, and access to recordings of signing calls.
• Who signs and how: Whether agents follow a script your counsel has reviewed, and how the agreement is presented and signed.
• Criteria and returns: Which signed clients you can return, such as those outside your case types or with an existing lawyer.
• Unreachable and dropped clients: What happens if you can't reach a client or they leave soon after signing.
• Consent records: Proof that each person agreed to be contacted, with the wording, timestamp and source.

How do you measure a signed retainer source?

Measure it by how many signed clients stay, and what their cases are worth. Signed retainer counts look strong on a report because every delivery is already a client. The measures that matter come later.

Are signed retainer leads right for your firm?

Signed retainers suit firms that can reach every new client quickly and give them a strong first experience, but don't want to run front-end intake themselves. They suit firms less well if client care after signing is stretched, or if counsel hasn't reviewed the model for each state you work in.

They're also a poor fix for weak intake. If your team struggles to convert web form leads or answer live transfers, the same team will struggle to keep signed clients. As Anthony puts it, "Sometimes they're not ready for lead gen, and I'm very open about that." Fix the foundation first.
