The document defines a partnership as the relation between two or more persons who have agreed to share profits from a business according to their agreed ratios. A partnership is formed through an oral or written agreement that contains terms about the relationship between partners, including the nature and duration of the business, capital contributions, and profit/loss shares. While not compulsory, registering the partnership provides benefits like allowing partners to file lawsuits related to the firm. The registration process involves submitting a statement with details of the firm and partners to the registrar of firms.
