What Is Form DE-150?
Form DE-150, Letters (Testamentary, of Administration, or Special Administration), is the one-page document that proves the personal representative's legal authority to act for the estate. Called 'Letters Testamentary' when there's a will and 'Letters of Administration' when there isn't. Banks and title companies require certified copies before they'll deal with you.
When & Where DE-150 Fits
You file DE-150 issued by the clerk after the judge signs the Order for Probate (DE-140). Nothing moves in the estate until Letters issue. This form is often handled by self-represented filers, though an attorney can review it. It sits in the appointment stage of a California probate. For the full sequence of forms and steps, see the California probate guide and the documents checklist.
