Wyo. Stat. § 17-21-407: Continuation of partnership beyond definite term or particular undertaking.

(a) If a partnership for a definite term or particular undertaking is continued, without an express agreement, after the expiration of the term or completion of the undertaking, the rights and duties of the partners remain the same as they were at the expiration or completion, so far as is consistent with a partnership at will.

(b) A continuation of the business by the partners or those of them who habitually acted in the business during the term or undertaking, without any settlement or liquidation of the partnership business, is prima facie evidence of an agreement that the business will not be wound up.
