Ohio Rev. Code § 1782.242: Effect of self-dealing.

No contract, action, or transaction shall be void or voidable with respect to a limited partnership for the reason that the contract, action, or transaction is among or affects the limited partnership and one or more of its partners, or that the contract, action, or transaction is among or affects the limited partnership and any other person in which one or more of the partners are directors, trustees, officers, or partners, or have a financial or personal interest, if any of the following applies:

(A) The material facts as to the partner or partners and their relationship or interest and as to the contract, action, or transaction are disclosed in writing to every partner before that partner is admitted to the partnership.

(B) The material facts as to the partner or partners and their relationship or interest and as to the contract, action, or transaction are disclosed in writing to all partners; the contract, action, or transaction is fair as to the limited partnership; and the disinterested general partners acting in good faith reasonably justified by the facts, authorize the contract, action, or transaction by a majority vote, even though the disinterested general partners constitute less than a majority of the general partners.

(C) The contract, action, or transaction is fair as to the limited partnership as of the time the contract, action, or transaction is authorized and approved by a majority in interest of the disinterested limited partners.
