In formal probates, you will have to publish notice of the case at least once. In larger estates, you will have to publish at least twice. If you are selling real estate, you must publish notice of the court hearing that will approve the sale of property. If there are heirs you cannot find, you must also publish notice again. There are very specific rules on notice in a probate case, including what type of publication is required, for how long notice must be published, and how far in advance of a court date notice must be published. These rules differ depending on the type of probate case that has been filed.
