Overview

Mariposa County is located in California with a population of approximately 17,152. The Superior Court of California, County of Mariposa handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

California probate is governed by the California Probate Code. The process begins with filing a Petition for Probate (Form DE-111) to admit the will and appoint a personal representative. The court then issues Letters Testamentary for testate estates or Letters of Administration for intestate estates.

California offers simplified procedures for small estates. For deaths occurring on or after April 1, 2025, if the gross value of the estate is $208,850 or less, you may be able to use a Small Estate Affidavit to transfer personal property without formal probate. There is also a simplified process for real property valued at $69,600 or less.

California law sets statutory fees for attorneys and personal representatives based on the value of the estate: 4% of the first $100,000, 3% of the next $100,000, 2% of the next $800,000, and 1% of the next $9 million.

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Spousal Property Petition: Assets passing to a surviving spouse may be transferred via a simplified petition (Form DE-221).
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If formal probate is needed, file a Petition for Probate (Form DE-111) with the Superior Court of California, County of Mariposa. Include:

  • Original Will and codicils (if any)
  • Notice of Petition to Administer Estate (Form DE-121)

  • Filing fee (approximately $435)

Step 3: Provide Notice

After filing, you must:

  • Publish notice in a newspaper of general circulation in Mariposa County (e.g., the Mariposa Gazette) for three successive weeks.

Step 4: Attend the Hearing

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors and the Franchise Tax Board.
