Begin by filing the Petition for Probate (Form DE-111) in the Superior Court for Los Angeles County. The process isn’t just paperwork; it requires the right supporting documents, from the certified death certificate and original will to a detailed list of heirs and proper notice forms. You’ll need to prepare, serve, and file notices for all interested parties, including mailing and publishing requirements, to be sure the court can move your petition forward without rescheduling. 📬

The court will set a hearing date, often several weeks out. If the filing and notifications are complete and accurate, the judge can appoint the executor or administrator and issue the authority (Letters) needed to start estate administration. Missing forms, incomplete notices, or errors often lead to setbacks, so a meticulous approach is crucial.
