A partnership is a business arrangement in which two or more people or other legal persons carry on a business together with the intention of making a profit. In England and Wales, the classic legal definition comes from section 1 of the Partnership Act 1890, which describes partnership as the relationship between persons carrying on a business in common with a view to profit.
The important elements are therefore joint business activity, a common commercial undertaking and an intention to generate profit. A partnership is not simply an informal collaboration between people: the legal relationship can arise from the parties' conduct and agreement even where they have not produced a sophisticated written partnership agreement. HMRC explains that a partnership can arise through an oral or written agreement and that a person for partnership purposes can include an individual, company or certain other legal persons.
A conventional UK general partnership is different from a limited liability partnership and from a limited partnership. In an ordinary partnership, all partners are generally jointly responsible for the partnership's debts and obligations, meaning that the personal financial exposure of partners can extend beyond the money they originally put into the business. The partners normally share responsibility for management and decision-making and share the profits according to their agreement or, where applicable, the statutory default rules.
Unlike a limited company, an ordinary partnership in England, Wales and Northern Ireland is not itself a separate legal person in the same way as an incorporated company. This distinction matters because contracts, liabilities, taxation, ownership and litigation can operate through the partners rather than through a completely separate corporate personality.
Partnerships are commonly used where several people bring complementary skills, capital, contacts, property, professional expertise or labour to a single commercial activity. For example, two consultants might establish a consultancy together, a solicitor and accountant might operate separate professional practices through a suitable partnership structure, or several people might jointly operate a retail, hospitality, property or professional-services business.
A partnership can be attractive because it can be comparatively straightforward to establish and administer, and because the partners can make decisions directly rather than creating a corporate board and shareholder structure. The partners can also agree how responsibilities, profits and working arrangements should be divided. The simplicity, however, does not remove the need to understand liability, tax, authority to bind the business and what happens if a partner dies, retires, becomes insolvent or wishes to leave.
A partnership agreement is one of the most important practical documents for a partnership, even where legislation supplies default rules. A well-drafted agreement can specify each partner's capital contribution, ownership interests, profit and loss allocations, decision-making rights, management responsibilities, banking arrangements, drawings, treatment of intellectual property, restrictions on competing activities, admission of new partners, retirement, expulsion, death, incapacity, dispute resolution and dissolution. Without suitable provisions, disagreements can become particularly difficult because partners may have different expectations about authority, workload and financial entitlement. UK government business guidance specifically recommends a partnership agreement dealing with decision-making, ownership changes, profits, financial matters, dispute resolution and dissolution.
Tax treatment is another major feature. In a conventional UK partnership, the partnership itself is generally treated as a transparent vehicle for income-tax purposes rather than as a company paying Corporation Tax on its trading profits. The partnership calculates its profits and each individual partner normally reports their share through Self Assessment and pays the relevant tax and National Insurance according to their circumstances.
The nominated partner has particular responsibilities for the partnership's tax return and records, while the individual partners remain responsible for their own tax obligations. This means that the accounting profit allocation and the amount of cash actually withdrawn by a partner are not necessarily identical, and partners need to plan for personal tax liabilities rather than assuming that all cash retained or distributed has the same tax consequences.
A partnership also involves the principle of mutual agency. Subject to the agreement and applicable law, a partner acting in the ordinary course of the partnership's business can create obligations for the partnership and therefore expose the other partners to consequences even where they did not personally negotiate the particular transaction. This makes trust, internal controls and clearly defined authority particularly important.
A partner's mistake, contractual commitment or failure to meet an obligation can therefore have consequences for the wider partnership. The unlimited liability characteristic of an ordinary partnership is consequently one of the most important distinctions from an LLP or limited company: partners should understand that commercial risk can reach their personal assets, subject to the particular facts, contractual arrangements and applicable law.
Partnerships have several advantages, including relatively straightforward formation, direct participation by owners, flexible internal arrangements, the ability to combine different resources and expertise, and potentially simpler administration than an incorporated structure. They can also make it easier for people to establish a business collaboratively without immediately introducing shareholders and directors.
Their disadvantages include unlimited personal liability in a general partnership, the possibility of disputes between partners, difficulty separating personal and business interests, dependence on the financial reliability of co-partners and potential disruption when ownership changes. A partnership agreement can reduce many of these risks but cannot automatically convert an ordinary partnership into a limited-liability structure. Where liability protection is important, the founders may instead consider an LLP or limited company.
The word partnership can also describe arrangements that are not legal partnerships in the strict statutory sense. Businesses frequently use terms such as strategic partnership, commercial partnership, joint venture or marketing partnership to describe contractual cooperation between independent organisations. Those arrangements do not necessarily create a Partnership Act partnership merely because the parties call themselves partners. The substance of the relationship, the parties' intentions, contractual provisions and their conduct are relevant.
A partnership should therefore be distinguished from co-ownership, employment, agency, a joint venture, a limited partnership, an LLP and a limited company. In practical business use, the central concept is people carrying on a business together, but the legal consequences depend heavily on the particular structure and jurisdiction.
