(a)
If any party to the transaction, other than the petitioner, does not consummate a transaction authorized by the court, the court, on application of the petitioner, after such notice to the parties to the transaction as the court directs, may vacate the order authorizing the transaction.
(b)
If the order authorized the sale or encumbrance of property, the petitioner may by supplemental petition apply to the court for an order authorizing any other sale or encumbrance of the property to the advantage, benefit, or best interests of the spouses or their estates. The supplemental petition and a notice of the time and place of the hearing shall be served and mailed as provided in Article 4 (commencing with Section 3130) except that (1) no further citation shall be issued and (2) a copy of the supplemental petition and a notice of the time and place of the hearing shall be served upon any person who has appeared as representative of a nonpetitioning spouse or upon counsel of record for a nonpetitioning spouse or as the court may otherwise direct.
(c)
If it appears to the court that the other sale or encumbrance is to the advantage, benefit, or best interests of the spouses or their estates and that the request in the supplemental petition that the transaction be authorized should be granted, the court may so order and may authorize the petitioner to do and perform acts and to execute and deliver all papers, documents, and instruments necessary to effectuate the order.
