Cal. Probate Code - PROB § 10150. Section 10150.
(a)
The personal representative may enter into a written contract with either or both of the following:
(1)
A licensed real estate broker to secure a purchaser for any real property of the estate. The broker may associate other licensed real estate brokers for this purpose, including use of a multiple listing service as defined in Section 1087 of the Civil Code.
(2)
One or more agents or brokers to secure a purchaser for any personal property of the estate. If the particular property to be sold or the particular manner of sale requires that the agent or broker be licensed, the contract may be made only with an agent or broker that is so licensed.
(b)
The contract may provide for payment of a fee, commission, or other compensation out of the proceeds of sale, but the contract is binding and valid as against the estate only for such amount as the court allows pursuant to Article 3 (commencing with Section 10160). No liability of any kind is incurred by the estate under the contract or a sale unless the sale is confirmed by the court, except for the obligations of the estate to the purchaser of personal property as to which title passes pursuant to Section 10259 without court confirmation or approval. The personal representative is not personally liable on the contract by reason of execution of the contract.
(c)
The contract may grant an exclusive right to sell property for a period not in excess of 90 days if, prior to execution of the contract granting an exclusive right to sell, the personal representative obtains permission of the court to enter into the contract upon a showing of necessity and advantage to the estate. The court may grant the permission when the personal representative is appointed or at any subsequent time upon ex parte application. The personal representative may execute one or more extensions of the contract granting an exclusive right to sell property, each extension being for a period not to exceed 90 days, if for each extension the personal representative obtains permission of the court upon ex parte application to extend the contract upon a showing of necessity and advantage to the estate of the extension.
