(a) Unless a partner does not have authority to act for the partnership in a particular matter and the person with whom the partner is dealing knows that the partner lacks authority, an act of a partner, including the execution of an instrument in the partnership name, binds the partnership if the act is apparently for carrying on in the ordinary course:

(b) An act of a partner that is not apparently for carrying on in the ordinary course a business described by Subsection (a) binds the partnership only if authorized by the other partners.

(c) A conveyance of real property by a partner on behalf of the partnership not otherwise binding on the partnership binds the partnership if the property has been conveyed by the grantee or a person claiming through the grantee to a holder for value without knowledge that the partner exceeded that partner's authority in making the conveyance.
