A partnership firm is one of the easiest ways for two or more people to run a business together. It is governed largely by the partnership deed the partners draw up, and registration is optional but worth having. Here's how a firm is formed, why the deed matters, what registration gives you, and how dissolution works.

Quick answer
A partnership firm is simple to start, but the partnership deed and registration decide what protection you actually have. Here's how it works, from formation to dissolution.
A partnership firm is a business owned by two or more people who agree to share its profits. Unlike a company or LLP, the firm is not a separate legal person — the partners and the firm are treated as one, and the partners are personally liable for the firm's debts, jointly and individually. This makes it cheap and quick to start with very light compliance, but it also means there is no limited-liability protection, which is the main trade-off to weigh against the simplicity.
The partnership deed is the written agreement that defines the firm. It records the partners' names, the nature of the business, capital contributions, profit- and loss-sharing ratios, the roles and powers of each partner, and how partners can be admitted or retire. It should also cover how disputes are settled and how the firm can be dissolved. While a partnership can technically exist on an oral understanding, a clear written deed prevents most disputes and is needed for registration, opening a bank account and tax filings, so always put it in writing.
Registering the firm with the Registrar of Firms is optional, but an unregistered firm is at a real disadvantage. An unregistered firm generally cannot sue to enforce its rights against third parties or partners in court, which can leave it exposed in a dispute. Registration involves filing an application with the firm's details and the deed with the Registrar of Firms for the relevant state. Given the protection it provides, registration is usually worth doing soon after the firm is formed rather than waiting until a problem arises.
A firm needs its own PAN and files its income-tax return separately from the partners, who are also taxed on their share of profits in line with the rules for partner income. Remuneration and interest paid to partners are deductible only within the limits the deed allows and the law prescribes. The firm should register for GST and any other taxes that apply to its activity, maintain proper books, and keep partner capital and current accounts updated. Because partners are personally liable, keeping clean records and clear accounts between partners matters even more here.
Partnerships change over time — a partner may join, retire, die or be removed, and any of these reconstitutes the firm and usually calls for a fresh or amended deed. Dissolution is the winding-up of the firm itself: the business stops, assets are sold, liabilities are paid, and any surplus is distributed among the partners according to the deed. Dissolution can be triggered by agreement, by the terms of the deed, or by events the law specifies. Handle it through a written dissolution deed and settle accounts cleanly so that no partner is left exposed to lingering claims.
Registration is optional, but strongly advisable. An unregistered firm generally cannot sue to enforce its rights against third parties or partners, so it is left exposed in a dispute. Registering with the Registrar of Firms is usually worth doing soon after the firm is formed.
Technically yes, but you should never rely on that. A clear written deed defines capital, profit-sharing, roles and exit terms, prevents most disputes, and is needed for registration, a bank account and tax filings, so always put the agreement in writing.
Reconstitution is a change in the partners while the firm continues; dissolution is winding the firm up entirely. When a partner joins, retires or leaves, the firm is reconstituted and the deed is updated. On dissolution the business stops, assets are sold, liabilities settled and any surplus shared among the partners.
