Offers may be submitted at anytime. An offer received by the listing broker at any time before a sale closes must be presented to the personal representative, unless the personal representative has expressly instructed the broker not to present it, or unless the offer is patently frivolous. Whether the offer is patently frivolous depends on the facts and circumstances at the time of the offer. The licensee’s safest course of action is to submit all offers of this type to the personal representative for his/her own determination.
