Oregon Revised Statutes Corporations and Partnerships § 70.255

(1) A general partner may withdraw from a limited partnership at any time by giving written notice to the other partners, but if the withdrawal violates the partnership agreement, the limited partnership may recover from the withdrawing general partner damages for breach of the partnership agreement and offset the damages against the amount otherwise distributable to the withdrawing general partner.

(2) A limited partner may withdraw from a limited partnership at the time or upon the happening of events specified in writing in the partnership agreement. If the partnership agreement does not specify in writing the time or the events upon the happening of which a limited partner may withdraw or a definite time for the dissolution and winding up of the limited partnership, a limited partner may withdraw upon not less than six months' prior written notice to each general partner at the general partner's address on the books of the limited partnership at its office in this state.
