An Investment Clause in a Partnership Deed is a contract provision between the partners of a business which outlines how investments, or additions of capital, should be handled. The clause typically requires each partner to make a certain cash investment and agree to any future increases in capital. This ensures that all partners are contributing equally to their joint venture and it also protects both parties from any losses likely to arise from the addition of new capital. As partners may have diverse financial situations and goals, this type of clause can help ensure that the entire enterprise remains profitable by keeping everyone’s investments fair.
