In a law firm, “of counsel” is a title for a lawyer who has a close, continuous, and personal working relationship with the firm but is neither a partner nor an associate. The American Bar Association, in Formal Opinion 90-357, limits the designation to relationships that are both regular and substantial. A one-off collaboration, a referral source, or an outside consultant who weighs in now and then does not qualify. The label signals to clients and courts that the lawyer is a genuine part of the firm’s team, subject to the same ethical rules and backed by the same accountability as the firm’s other attorneys.
How Of Counsel Differs From Partners and Associates
Partners own a piece of the firm. They vote on management, share in profits, and absorb losses when revenue dips. An of counsel attorney has none of that. No equity stake, no seat on the management committee, no exposure to firm losses.
Associates sit at the other end. They’re salaried employees working under supervision, usually on a track toward partnership. An of counsel lawyer typically has more autonomy and more seniority than an associate but isn’t climbing that ladder. The role occupies its own lane, with an independence partners and associates don’t share in quite the same way.
Who Usually Holds the Title
A few recurring situations produce most of counsel arrangements.
- Senior partners winding down. A longtime partner approaching retirement may step back from management and a full caseload while staying available for consultation and select client matters. The firm keeps the institutional knowledge without carrying a full equity partner.
- Niche specialists. A firm that handles general commercial litigation might not generate enough appellate or regulatory work to justify a full-time partner in that area. Bringing in a specialist as of counsel lets the firm offer the service without the overhead.
- Former government lawyers and judges. Attorneys leaving public service often carry deep subject-matter expertise but no appetite for immediate partnership responsibilities. Of counsel provides a landing spot.
- Pre-partnership evaluation. Some firms use the designation as a trial period, especially for lateral hires whose client base the firm wants to evaluate before committing.
Conflicts of Interest Are Imputed to the Whole Firm
This is where the designation has its sharpest teeth. For conflict-checking purposes, an of counsel lawyer is treated as fully associated with the firm. Under ABA Model Rule 1.10, when any lawyer in a firm has a conflict of interest under Rule 1.7 (current clients) or Rule 1.9 (former clients), that conflict spreads to every other lawyer in the firm.1American Bar Association. Rule 1.10: Imputation of Conflicts of Interest: General Rule
In practice, the of counsel lawyer’s entire client history gets loaded into the firm’s conflict database, and the firm’s existing client list constrains what the of counsel lawyer can take on. If the of counsel attorney previously represented a company in a trade-secret dispute, the firm may be barred from suing that company for another client. The reverse works the same way. Firms that skip thorough conflict checks when onboarding an of counsel attorney invite disqualification motions and malpractice exposure.
Malpractice and Firm Liability
A law firm is generally responsible for the professional conduct of its of counsel attorneys, the same way it would be for a partner or associate. Because the firm holds the lawyer out to the public as part of its team, courts treat the relationship as creating vicarious liability. If the of counsel attorney makes an error that harms a client, the firm can be on the hook.
Malpractice insurance is the practical consequence. The of counsel lawyer should be covered under the firm’s professional liability policy from the start of the relationship. Many risk management guides also recommend that the of counsel attorney maintain a separate individual policy, ideally with the same insurer, to avoid coverage gaps.
How Of Counsel Lawyers Get Paid
The ABA has taken the position that the method of compensation does not affect whether the of counsel designation is proper, which opens the door to a range of arrangements. Common structures include a fixed salary, hourly billing with the firm collecting and distributing fees, a percentage of revenue from the attorney’s own clients, bonuses tied to billable hours or collections, and in some cases profit participation.
Fee-splitting rules add a wrinkle. ABA Model Rule 1.5(e) restricts how lawyers at different firms can divide fees: the split must be proportional to the work each lawyer performed (or both must accept joint responsibility), the client must agree in writing, and the total fee must be reasonable.2American Bar Association. Rule 1.5: Fees Jurisdictions are split on whether an of counsel attorney counts as part of the firm for this purpose. Some treat the of counsel lawyer as inside the firm, so the parties can structure compensation however they like. Others treat the of counsel attorney as separate, which triggers the full client-consent-and-proportionality framework. The safer approach is to assume Rule 1.5(e) applies until local authority says otherwise.
Employee or Independent Contractor for Tax Purposes
Whether an of counsel attorney receives a W-2 or a 1099 depends on the actual working relationship, not the title. The IRS looks at behavioral control (does the firm direct how and when the lawyer works?), financial control (does the firm set rates, reimburse expenses, or provide office space?), and the nature of the relationship (written contract, benefits, expected duration).3Internal Revenue Service. Independent Contractor (Self-Employed) or Employee?
An of counsel attorney who sets their own hours, uses their own equipment, and runs cases with minimal oversight looks like an independent contractor. One who works from the firm’s office on a set schedule, uses firm resources, and receives benefits looks like an employee. Misclassification can produce back payroll taxes, penalties, and interest for the firm, and lost self-employment deductions for the attorney.
What It Means If You’re Hiring the Firm
From a client’s perspective, an of counsel attorney is functionally part of the firm for the work they handle. The firm stands behind the attorney’s work product. The attorney should be covered by the firm’s malpractice insurance. Confidential information you share with the of counsel lawyer is treated the same as information shared with any other firm attorney. You’re not getting a freelancer with a loose affiliation. You’re getting someone the firm has vouched for by putting the name on the door.
The practical upside is that of counsel lawyers often bring specialized expertise or seasoned judgment the firm’s regular roster may lack. If your matter touches appellate strategy, a narrow regulatory niche, or the kind of experience that only comes with decades of practice, the of counsel attorney may be exactly who you want on it. One question worth asking before you sign an engagement letter: confirm that the of counsel attorney is covered under the firm’s malpractice policy. Any reputable firm will say yes without hesitation.
