The partnership deed defines the roles and duties of the partners pertaining to the general administration and operation of the firm. It gives them the right to determine relationship inter-se. These include aspects like profit sharing, the roles of each partner, etc. This deed can be altered through the express or implied consent of the partners. Section 11 of the Partnership Act states that partners can be restrained from carrying on a business similar to the business of the partnership but such a clause must be expressly stated in the partnership deed.
