What Is a Law Firm Partner? Roles Explained

Q: What is the difference between an equity and a non-equity partner?

An equity partner owns part of the firm and shares in its profits (and usually its risks). A non-equity partner carries the partner title but is typically paid a fixed salary, sometimes with a bonus, and has little or no ownership stake or vote. Exact terms depend on each firm's partnership agreement.

Maybe you've seen "Partner" next to a lawyer's name and wondered what it really means, or you're a law student weighing the partnership track. Here's a clear, friendly explanation of the title, the different kinds of partners, and the ethics rules that come with it.

Short answer: A law firm partner is a lawyer who is a member or co-owner of the firm, rather than an employee. Equity partners share in the firm's profits and ownership, while non-equity partners have the title and seniority but are usually paid a salary. Partners also carry special ethical duties: under ABA Model Rule 5.1 they must take reasonable steps to ensure that all lawyers in the firm follow the rules of professional conduct.

Equity vs non-equity partners

Not every partner is an owner. Many firms, especially larger ones, have two tiers:

Equity partners own a share of the firm. They typically contribute capital, share in profits (and losses), and vote on major decisions such as admitting new partners.
Non-equity partners (sometimes called "income" or "salaried" partners) hold the title and often lead client matters, but they are usually paid a fixed salary plus a possible bonus and have limited or no ownership or voting rights.

Smaller firms may have just one tier. The details, including how profits are split and what happens when a partner leaves, come from the firm's partnership or shareholder agreement and state business law, not from a single national rule. Whether a partner can be personally liable for the firm's debts also depends on how the firm is organized (for example, as a general partnership, a limited liability partnership or a professional corporation) and on state law.

Partners, associates and of counsel

Associates are lawyers employed by the firm. Many are on a track that may lead to partnership after a number of years, though firms set their own timelines and criteria.
Partners own or help run the firm, bring in and manage client work, and supervise others.
Of counsel is a flexible title for a lawyer with a close, regular relationship with the firm who is not a partner or associate, such as a retired partner, a senior specialist or a lawyer who works part-time with the firm.
Paralegals and staff are not lawyers, and partners must supervise their work too (ABA Model Rule 5.3 covers non-lawyer assistants).

Titles must not mislead clients. The official comment to ABA Model Rule 7.1 notes that lawyers "may not imply or hold themselves out as practicing together in one firm when they are not a firm."

What partners must do under the ethics rules

Rule 5.1 gives partners and supervising lawyers three layers of responsibility:

Firm-wide systems (5.1(a)). Partners and managers must make reasonable efforts to ensure the firm has measures in place so its lawyers comply with the rules, such as conflict checks, deadline calendars and client-funds procedures.
Direct supervision (5.1(b)). A lawyer with direct supervisory authority over another lawyer must make reasonable efforts to ensure that lawyer complies.
Responsibility for others' violations (5.1(c)). A lawyer is responsible for another lawyer's violation if they order or knowingly ratify it, or if they are a partner or supervisor who knows of the conduct when its consequences can still be avoided or reduced but fails to take reasonable action.

For clients, this means a partner can't simply blame a junior lawyer if a known problem was ignored. If something has gone wrong with your case, you can raise it with the supervising partner, and our guide on what to do when your lawyer drops your case covers related situations.

Who can be a partner? Rule 5.4 and the Arizona and Utah exceptions

Traditionally, only lawyers can own a law firm. ABA Model Rule 5.4 says:

"A lawyer or law firm shall not share legal fees with a nonlawyer," with narrow exceptions (Rule 5.4(a));
"A lawyer shall not form a partnership with a nonlawyer if any of the activities of the partnership consist of the practice of law." (Rule 5.4(b)); and
a lawyer may not practice in a for-profit professional corporation in which a non-lawyer owns an interest, is a director or officer, or can control a lawyer's professional judgment (Rule 5.4(d)).

The goal is to protect lawyers' independent judgment. Two states have moved away from this model:

Arizona. In August 2020 the Arizona Supreme Court approved eliminating its ER 5.4, effective January 1, 2021. Businesses that include non-lawyer owners must be licensed as Alternative Business Structures (ABS).
Utah. In August 2020 the Utah Supreme Court created a regulatory sandbox under Standing Order 15, allowing approved entities, including some with non-lawyer ownership, to offer legal services under supervision. According to Utah's Office of Legal Services Innovation, the sandbox is closed to new applications, the ABS-only portion closed at the end of 2024, and the program is set to sunset on August 14, 2027.

Rules in this area are changing, so check the current position with the relevant state supreme court before relying on it.

Becoming a partner

There's no single path. Firms typically look at the quality of a lawyer's work, client relationships and business generation, and contribution to the firm. Some lawyers become partners by founding their own firm. Every partner must first be a licensed attorney; if you're curious about that step, see what does bar stand for in law.

What is the difference between an equity and a non-equity partner?

An equity partner owns part of the firm and shares in its profits (and usually its risks). A non-equity partner carries the partner title but is typically paid a fixed salary, sometimes with a bonus, and has little or no ownership stake or vote. Exact terms depend on each firm's partnership agreement.

Is a partner more senior than an associate?

Generally yes. Associates are lawyers employed by the firm, often on a track toward partnership. Partners own or help manage the firm and, under ABA Model Rule 5.1, have duties to make sure the firm's lawyers follow the ethics rules.

What does "of counsel" mean?

It usually describes a lawyer with a close, ongoing relationship with the firm who is neither a partner nor an associate, such as a senior lawyer who has stepped back from partnership or a specialist who works with the firm regularly. Firms must not use titles in a misleading way.

Can a non-lawyer be a partner in a law firm?

In most US states, no. ABA Model Rule 5.4, which most states have adopted in some form, bars lawyers from forming a partnership with a non-lawyer to practice law. Arizona eliminated its version of the rule effective January 1, 2021 and licenses Alternative Business Structures, and Utah runs a time-limited regulatory sandbox.

Does my partner-level lawyer have to supervise the associates on my case?

Under Rule 5.1, partners must make reasonable efforts to ensure the firm has measures in place so all its lawyers follow the rules, and a lawyer with direct supervisory authority must make reasonable efforts to ensure the supervised lawyer complies. You can always ask who is responsible for your matter.
