Pro Socio Law and Legal Definition
Pro Socio is a Latin term which means ‘on behalf of a partnership.’ A court application stated to be pro socio is made on behalf of a partnership.
The following is an example of a caselaw using the term:
Ordinarily, an action, pro socio, did not lie to enforce a right to a general account between the partners until after the dissolution of the copartnership. But in special cases, an action pro socio lay for an account during the existence of the partnership. If one partner was prevented by the others from an equal participation in any of the partnership property, he might, even during the continuance of the copartnership, maintain the action pro socio. [Kelly & Frazier v. Robertson, 10 La. Ann. 303 (La. 1855)]
