Law firm

A law firm is a business entity created by one or more lawyers. These professionals work together to provide legal services to individuals or large corporations. The primary role of a firm is to advise clients about their legal rights and responsibilities. Lawyers also represent clients in business transactions and various civil or criminal cases. Because they deal with complex rules, law firms are essential to how legal systems function.

Law firms use different organizational structures depending on their local laws. A sole proprietorship consists of just one attorney who handles all profits and liabilities. In a general partnership, all member attorneys share ownership and profits together. Some firms operate as professional corporations by issuing stock to their attorneys. Others use a limited liability company (LLC) model, where owners are called members. In a professional limited liability company (PLLC), these members are not directly liable to third-party creditors. A limited liability partnership (LLP) allows partners to share ownership while remaining protected from the negligence of other partners.

Rules regarding ownership are often strictly controlled to prevent conflicts of interest. In many countries, including most of the United States, only lawyers may own or manage a law firm. This rule prevents firms from raising money through public stock offerings. Instead, they must use capital contributions from partners or take on debt through lines of credit. The American Bar Association's Model Rules of Professional Conduct codifies this restriction. Many believe this protects a lawyer's duty to be a loyal advocate and an honest officer of the court. Critics argue these rules limit innovation and make legal services more expensive.

Some regions have begun to change these traditional ownership rules. The United Kingdom implemented reforms through the Legal Services Act of 2007. This allowed firms to take on a limited number of non-lawyer partners. It even enabled businesses like banks or grocery stores to hire lawyers for basic services. In the United States, Arizona became the first state to authorize "alternative business structures" (ABS) in 2020. This allows for non-lawyer owners under specific conditions. For example, the accounting firm KPMG became an authorized ABS in Arizona. However, it cannot provide legal services to clients it already audits.

Multinational law firms must manage complex structures to operate in many different countries. Some jurisdictions, like Japan or Hong Kong, restrict partnerships between local and foreign lawyers. To solve this, some firms use a unique structure called a Swiss Verein. This model was pioneered by Baker McKenzie in 2004. In a Swiss Verein, different regional partnerships share branding and administrative costs. However, they maintain separate revenue pools and different compensation structures for their partners. Other large firms operate as a single worldwide partnership to navigate local regulations.

Inside a firm, there is a clear hierarchy of roles and ranks. Partners are the joint owners and directors of the legal operation. Associates are employees who work toward the goal of becoming partners. Some firms follow the "up or out" policy, which was part of the early 20th-century Cravath System. Under this policy, associates who are not promoted to partner must resign. Making partner is a prestigious achievement due to high competition. Some large firms even use a two-tiered model with equity partners and non-equity partners. Equity partners share in profits and losses, while non-equity partners receive a fixed salary.

Law firms use specific financial statistics to measure their success and prestige. One common metric is profits per equity partner (PPP). This is calculated by dividing net operating income by the number of equity partners. Another measure is revenue per lawyer (RPL), which shows the gross revenue divided by the total number of lawyers. Firms also look at the average compensation of partners (ACP). This includes both equity and non-equity partners to provide a more inclusive view. These numbers help rank firms and attract new talent.

History shows that law firms have existed for a very long time. The oldest law firm still in continuous practice in the United States is Rawle & Henderson. It was founded in 1783 in Philadelphia. Another very old firm is Cadwalader, Wickersham & Taft, which started in 1792 in New York City. In many large firms, attorneys may also hold the title of "of counsel." These individuals are often senior lawyers who manage their own cases and supervise associates. They allow the firm to share its brand name and resources with experienced professionals.
