Law firm guide
For firms whose clients are companies, prospecting means researching companies with a moment that creates legal work, finding a warm path to the person who hires outside counsel, and sending a truthful written first touch.

The short answer
Prospecting works differently for a law firm when your clients are businesses. Companies rarely fill in intake forms, and legal work follows business moments like a contract win, a new site or an acquisition. What fits is research, a warm introduction and a truthful written first touch, checked against your state's rules. Clean is research that shows firms which companies to approach and why.
Search for ways to find clients as a lawyer or attorney and most of what comes back is written for consumer practices. The prospects on sale are individuals with a personal legal problem, priced per inquiry or per call, and the advice is about intake speed and ad spend. That model works when a person with a problem goes looking for a lawyer and a vendor puts a firm in front of them.
This guide is for firms whose clients are companies: corporate and M&A, commercial real estate, government contracts, trade and customs, and regulatory work. It is written for the people who own growth there, from managing partners and practice group leaders to associates building a book and the BD team that preps their pitches. If your matters start when a company does something that creates legal work, the consumer playbook does not transfer. For the wider picture, start with Clean for law firms; for the relationship side, see how to get corporate clients as a lawyer.
Four things change when the client is a company, and each one undercuts the idea of buying inquiries.
ABA Model Rule 7.2(b) says a lawyer may not give anything of value to a person for recommending the lawyer's services. The exceptions are narrow: reasonable advertising costs, the usual charges of a legal service plan or a not-for-profit or qualified lawyer referral service, buying a practice under Rule 1.17, a non-exclusive reciprocal referral agreement with another lawyer or professional that the client is told about, and nominal thank-you gifts.
The comments are where paid prospecting is covered. Comment [3] lets a lawyer pay employees, agents and vendors for marketing or client development services, business development staff included. Comment [5] lets a lawyer pay others for finding potential clients on three conditions: the provider does not recommend the lawyer, the payment fits Rules 1.5(e) and 5.4 (dividing fees and professional independence), and the provider's communications fit Rule 7.1. So the vendor cannot say or imply that it recommends you, that it refers people without being paid, or that it analyzed someone's legal problem before picking you.
The firm also answers for its vendors. Comment [5] points to Rule 5.3 (supervising nonlawyers) and Rule 8.4(a) (breaking the rules through someone else). ABA Formal Opinion 501 (2022) applies the same idea to live solicitation: in some circumstances a lawyer answers for live calls and meetings that employees or a hired marketing firm carry out on the lawyer's behalf. In practice, know exactly what any vendor says to prospects in your name.
The ABA text is a model. Your state's version is the rule that binds you, and some states regulate paid client sources directly.
Florida is the clearest example. Its Rule 4-7.22 defines a qualifying provider as anyone who gets a benefit for the direct or indirect referral of prospective clients, and the definition covers directories that list lawyers together and anyone providing tips about prospective clients. A Florida lawyer may work with a qualifying provider only if it meets the rule's 12 conditions, among them no communication or contact with prospects that would break the rules if the lawyer made it, no fee sharing (bar-approved referral services aside), an annual report to the Bar naming participating lawyers, and lawyers from at least 4 different firms. The lawyer must tell the Bar within 15 days of joining or leaving a provider, and a lawyer who skips due diligence on the provider answers for its compliance.
California's wording is broader. Its Rule 7.2(b) bars giving anything of value to a person for the purpose of recommending or securing the lawyer's services, outside its listed exceptions. Its comments still let a lawyer pay marketing and client development vendors, business development staff included, but they do not repeat the ABA's comment on paying others to find potential clients. Before you pay any vendor that helps you find clients, Clean included, read your own state's advertising and solicitation rules and ask ethics counsel how they apply. Nothing on this page is legal or ethics advice.
Here is how the common approaches compare for a firm that sells to companies. The ethics column is a starting checklist, not a ruling for your state. For how these fit a full plan, see a law firm marketing plan for business clients.
Prospecting approaches for law firms that serve businesses
| Approach | Fit for business clients | Cost model | Ethics watch-outs |
|---|---|---|---|
| Pay-per-inquiry vendors for consumer matters | Poor. The inquiries come from individuals looking for help, not companies with corporate work. | Per inquiry, per call or a monthly fee | Rule 7.2 comment [5]: the vendor may not recommend you or imply it analyzed the problem. Florida treats anyone who provides tips about prospective clients for a benefit as a qualifying provider. |
| Legal directories and rankings | Weak on their own. In one small 2025 survey of law firm marketing leaders, directories and awards ranked the least useful marketing activity. | Listing or profile fees where paid, plus staff time on submissions | Rule 7.2(b)(1) and comment [3] let you pay for directory listings as advertising. Florida's qualifying-provider rule covers directories that list lawyers together for a benefit. Describe rankings in ways that do not mislead under Rule 7.1. |
| SEO and written content | Moderate. It builds the credibility a GC checks, but it waits for the reader to find you. | Lawyer and staff time, or an agency retainer | A website aimed at the general public is not solicitation (Rule 7.3 comment [1]). Keep it truthful under Rule 7.1 and name clients only with their consent. |
| Referrals and introductions | Strong. Trust transfers from someone the buyer already knows. | No payment for the recommendation itself, beyond Rule 7.2(b) exceptions such as nominal thank-you gifts and non-exclusive, disclosed reciprocal agreements | Do not script what an introducer says about a specific matter, and do not reward introducers beyond nominal gifts. |
| Research on company moments | Strong. It starts from a company with a reason to need the practice and a path to the person who hires counsel. | Research time, or a subscription to a research tool | A first touch that offers help with a specific matter is a solicitation under Rule 7.3(a). Keep it written and truthful, follow state add-ons such as Florida's, run conflicts first, and stop if they decline. If you pay for a tool, ask ethics counsel how your state's rules on paid client sources apply. |
For a business-client firm, prospecting is research. You look for a company where a business moment creates work in your practice, check that you can take the work (run conflicts, and never pitch the other side of a deal your firm is on), and find the person who hires outside counsel plus a way to reach them that they will welcome. Each target should come with four things: the company, the reason, the practice area it touches and the person who decides.
Example (invented): a 40-lawyer regional firm's regulatory group learns that a mid-size home health agency has been licensed to operate in a neighboring state. The group runs conflicts, finds that one of the firm's partners knows the agency's CEO through a state industry association, and asks that partner for an introduction. That is the whole process: a moment, a practice, a conflict check and a path in. The moments worth watching, and the work each one brings:
Start with a warm path: a partner who worked with the GC at a prior firm, a client who sits on the company's board, a banker the owner trusts. An introduction from someone the buyer knows is worth more than any note you write, and seeing who can introduce you shows where those paths exist. Let the introducer speak in their own words.
When there is no warm path, write. ABA Rule 7.3(b) bars live person-to-person solicitation when a significant motive is pecuniary gain, unless the person is a lawyer, has a family, close personal or prior business or professional relationship with you, or routinely uses the type of legal service you offer for business purposes. That exception does not cover every executive: an owner facing a first import or a first acquisition may never have hired that kind of lawyer.
California has no business-purposes exception, and Florida treats cold calls as prohibited solicitation. So skip cold calls, live video and DMs, and never ask staff or an agency to make contact you could not make yourself. Writing is the channel the Supreme Court protected: in Shapero v. Kentucky Bar Association (1988) it held that a state may not categorically ban truthful, nondeceptive letters to people known to face a particular legal problem. States can still regulate those letters, and many do.
A good note says who you are, names the business moment plainly and offers one general observation about the legal work that kind of moment usually brings. It avoids urgency, does not look like a legal notice, does not suggest you have already analyzed their legal problem, makes no comparative or results claims, makes no "certified" claim without a named certifying body, and includes your name and contact information. Florida adds "Advertisement" at the start of the subject line, a statement of your background, training and experience that covers the area of law involved, a disclosure of how you learned of a specific occurrence, and submission to the Bar for review at least 20 days before first use unless exempt. California requires an "Advertisement" marking in some cases. If the recipient says no, stop.
Cost per inquiry is the number consumer vendors sell against. For corporate work it tells you little, because the value sits in the relationship and one company can bring matters for years.
Track the steps you control, review them monthly by practice group, and fold the routine into a weekly business development system so it survives a busy month. The steps worth counting:
Clean is research your firm uses to decide which companies to approach and why. It is built for business clients only: it finds companies, not individuals, and it does not find consumer cases. It finds companies at moments that create legal work: a large contract won, a real estate deal or new site, new import activity, a new license or registration, and an acquisition. For each company it gives the reason, the practice area it touches and the person who hires outside counsel, usually the general counsel, the CEO or the owner.
Open a company in Clean to see the practice areas it touches, who in your team's network can introduce you, and every record behind it, each with a note on the legal work it creates. You set who to look for by industry, company size, region and the kind of matter you want, and who to leave out, such as current clients. Clean does not use intent data built from ad clicks, page views or content downloads. It works from records of what companies actually do.
Your lawyers decide whether and how to reach out; Clean does not send messages for you. Read how Clean works, or book a demo to see companies in your market with a moment that creates work in your practice, and who to reach.
Prospecting is any method a firm uses to find people or companies that may need its legal services. For consumer practices it usually means buying inquiries from vendors. For firms that serve businesses it means researching companies with a moment that creates legal work, such as a contract won or an acquisition agreed, then finding the person who hires outside counsel and a warm or written way to reach them.
Under the comments to ABA Model Rule 7.2, a lawyer may pay others for finding potential clients if the provider does not recommend the lawyer, the payment fits the rules on dividing fees and professional independence, and the provider's communications are not false or misleading. Lawyers may also pay marketing and client development vendors. States differ: Florida's Rule 4-7.22 covers anyone who gets a benefit for providing tips about prospective clients to lawyers and limits which ones a lawyer may use. Check your state's rules and ask ethics counsel.
The legal marketing vendors that dominate search results mostly sell inquiries from individuals with consumer matters, priced per inquiry or per call. Corporate work rarely arrives that way. Companies hire outside counsel through people they trust, after business moments such as a contract award, a new site or an acquisition. Firms that serve businesses are better served by research on those moments, warm introductions and truthful written first touches, checked against their state's rules.
Not by cost per inquiry. For corporate work the value sits in the relationship, and one company can bring matters for years. Track the steps you control instead: companies researched with a clear moment and practice area, conflicts cleared, warm paths found and introductions made, written first touches sent and replies, first conversations, engagement letters signed, and origination credit on matters that started from the research. Review them monthly by practice group.
Clean is research your firm uses to decide which companies to approach and why. It is built for business clients only and finds companies, not individuals. For each company it shows the moment that creates legal work, the practice area it touches, the person who hires outside counsel, who in your network can introduce you, and the records behind each reason. Your lawyers decide whether and how to reach out. As with any vendor you pay, ask ethics counsel how your state's rules apply.
