15 Pa.C.S. § 8633: No liability as limited partner for limited partnership obligations.

A debt, obligation or other liability of a limited partnership is not the debt, obligation or other liability of a limited partner. A limited partner is not personally liable, directly or indirectly, by way of contribution or otherwise, for a debt, obligation or other liability of the partnership solely by reason of being or acting as a limited partner, even if the limited partner participates in the management and control of the partnership. This subsection applies regardless of the dissolution, winding up or termination of the partnership.
