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