A business enterprise entered into for profit which is owned by more than one person, each of whom is a “partner.” A partnership may be created by a formal written agreement, but may be based on an oral agreement or just a handshake. Each partner invests a certain amount (money, assets and/or effort) which establishes an agreed-upon percentage of ownership, is responsible for all the debts and contracts of the partnership even though another partner created the debt or entered into the contract, has a share in management decisions, and shares in profits and losses according to the percentage of the total investment. Often a partnership agreement may provide for certain division of management, shares of investment, profit and/or rights to buy out a partner upon leaving the partnership or death. Each partner owes the other partners a duty of full disclosure of information which affects the business and cannot commandeer for himself/herself business opportunities which rightfully belong to the partnership. A partnership which does business under a trade name must file with the county or state a certificate of “doing business under a fictitious name,” which gives notice to the public of the names of partners and the business address.
