The Indian Partnership Act, 1932 defines several default rules which automatically apply when there is no written deed. One such rule specifies that if a partner gives a loan to the firm separate from his capital, he is entitled to an interest at 6% per annum. This interest is a priority payment and must be given even if the partnership makes a loss. The Act ensures fairness by compensating partners who extend financial support to the firm. All other interest-related matters, like interest on capital or drawings, depend on the deed, but interest on loan always defaults to 6%.
