Does a defective incorporation result into a partnership?

The answer depends on whether or not there is a clear intent to participate in the management of the business affairs on the part of the investor. Parties who intends to participate or has actually participated in the business affairs of the proposed corporation would be considered as partners under a de facto partnership. On the other hand, parties who took no part notwithstanding their subscriptions do not become partners with other subscribers. (Pioneer Insurance v. CA, G.R. No. 84197, July 28, 1989)
