How a UK law firm is structured as an LLP

Walk into almost any mid-sized or large law firm in England and Wales and you are dealing with a limited liability partnership, or LLP. The form was created by the Limited Liability Partnerships Act 2000, which came into force in 2001, and it has become the default structure for professional partnerships that want the flexibility of a partnership with the protection of limited liability.

An LLP is a body corporate. That matters: unlike a traditional partnership, it has a legal personality separate from that of its members, so it can own property, enter contracts and sue or be sued in its own name. It is brought into existence by incorporation at Companies House, and it must file an incorporation document and, thereafter, annual accounts and a confirmation statement, much as a company does. The people who own the business are called members rather than partners or shareholders.

The central attraction is in the name. In a general partnership the partners are jointly liable for the debts of the firm without limit, so a single catastrophic claim can reach a partner’s personal assets. In an LLP, a member’s liability is generally limited to the amount they have agreed to contribute, and the firm itself carries the liability for its obligations. Individual members can still be personally liable for their own negligence, and professional indemnity insurance sits behind the whole structure, but the form removes the open-ended exposure that made the old partnership model increasingly uncomfortable for large firms.

An LLP has no share capital and cannot raise equity from outside investors in the way a company can. Only members hold an economic stake, so bringing in outside money means admitting a new member rather than issuing shares. This is one reason the alternative business structure regime, which does allow external ownership of regulated firms, has attracted attention from private equity.

For tax, an LLP is transparent. The entity itself does not usually pay corporation tax on its trading profits; instead the profits are apportioned to the members, who are taxed as self-employed partners on their respective shares. That treatment is a large part of why the partnership model persists even after incorporation.

The rules between members are set by an LLP agreement, a private document that governs profit sharing, decision-making, the admission and retirement of members, and what happens when someone leaves. Where firms distinguish between equity members, who share in profits and take on capital and risk, and fixed-share or salaried members, who receive a more predictable return, that distinction lives in the agreement rather than in the statute. The Act supplies default rules, but in practice the agreement is where a firm’s economics are really decided.
