California Probate Form DE-315 Order Determining Succession to Real Property is the order that goes with the DE 310 petition. That is, first you file the form 310 petition and if it’s approved the Judge would sign a form 315 order. Of course you have to complete the order, to match the petition, and then submit it to the Court. Since this generally involves real property you will need to get a certified copy of the order and record it with the county recorder. Also, as a side note, remember if this is a parent to child exclusion you must file your parent to child exclusion form, with the county assessor within 3 years of death and BEFORE any transfer to a third party. This is a common problem that can cause a large tax bill increase or a large supplemental property tax bill.
