What is a partner's interest in a partnership primarily considered to be?

A partner's interest in a partnership is primarily considered to be the share of profits and surplus. This concept stems from the nature of partnerships, where each partner typically has a financial stake in the business, represented by their right to receive a portion of the profits generated by the partnership. This interest is crucial because it not only reflects the economic relationship each partner has with the partnership but also indicates their investment in the business's success.

While partners may have roles in management, responsibilities for debts, and rights regarding decision-making, these aspects are secondary to the financial interest held by a partner. The share of profits is what fundamentally defines a partner's stake, aligning their incentives with the performance of the partnership. Thus, understanding a partner's interest through the lens of profit and surplus distribution gives insight into the financial and operational dynamics within a partnership.
