20 Pa.C.S. § 7791: Abandonment of property.

If any property is so burdensome or is so encumbered or is in such condition that it is of no value to the trust, the trustee may abandon it. If property without value cannot be abandoned without transfer of title to another or without a formal renunciation, the court may authorize the trustee to transfer or renounce it without consideration if it finds that this will be for the best interests of the trust.
