Whitney – highest point in the contiguous US at 14,505 ft); Mammoth Mountain (adjacent Mono County but primary access for many via Bishop); Manzanar National Historic Site (Lone Pine – WWII Japanese American internment camp; one of the most moving NPS sites in California)
Notes: Inyo County contains some of the most extraordinary landscapes on Earth; the visual drama of the Eastern Sierra – with the White Mountains’ Ancient Bristlecone Pines (Methuselah Tree is over 4,800 years old – the oldest known living non-clonal tree), Death Valley’s alien landscape, the Alabama Hills’ granite formations with Mt. Whitney looming behind, and the John Muir Wilderness – is unmatched; Manzanar NHS is a profound and important historical site where 10,000 Japanese Americans were incarcerated during WWII in plain sight of the same Sierra Nevada that the Japanese American soldiers fought overseas to defend; it is one of California’s most emotionally significant historical sites

Notes: The LADWP’s historic diversion of the Owens River (beginning in 1913) drained Owens Lake and created one of the worst man-made dust pollution events in US history – the dry Owens Lake bed became a source of massive dust storms containing arsenic, cadmium, and other toxics that plagued the Eastern Sierra for decades; under a Great Basin Unified Air Pollution Control District order, LADWP has spent over $2 billion implementing dust suppression measures (shallow flooding, gravel spreading, vegetation planting) on the lake bed – it is the world’s largest dust control project; air quality has improved but management continues; Long Valley Caldera (Mammoth Lakes area) is one of the world’s most potentially dangerous volcanic systems – the USGS Volcano Hazards Program maintains continuous monitoring; a Caldera eruption would be catastrophic; Death Valley’s extreme conditions require specialized environmental management; LADWP’s land holdings complicate county environmental management throughout the Owens Valley
About Inyo County
Inyo County is one of the most geologically and ecologically extraordinary counties in the United States – a vast, sparsely populated eastern Sierra corridor encompassing both the highest and lowest points in the contiguous United States within roughly 80 miles.
Bishop (population ~3,800) is the county’s largest city and primary commercial center – an eastern Sierra hub for rock climbers, backpackers, hikers, and fishermen accessing the John Muir Wilderness, Bishop Creek Canyon, and the Mammoth Lakes area. The Owens Valley Paiute and Shoshone communities maintain cultural connections to the valley’s long human history.
Lone Pine (population ~2,000) sits at the foot of Mount Whitney and the Alabama Hills – the rounded granite formations of the Alabama Hills have served as the filming location for more Hollywood westerns and action films than any other location in the world, with over 400 productions filmed there since the silent era.
Death Valley National Park – covering most of the county’s southern half – is the hottest, driest, and lowest national park in the United States. The park’s record high temperature of 134°F (1913) is the highest reliably recorded air temperature on Earth.
The Ancient Bristlecone Pine Forest in the White Mountains contains Methuselah – a Great Basin bristlecone pine estimated at 4,855 years old, the oldest known living non-clonal organism on Earth.
Manzanar National Historic Site – the first of ten Japanese American internment camps established during World War II – is preserved as a stark reminder of the forced relocation of 120,000 Japanese Americans from the West Coast between 1942 and 1945.

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Inyo County has two courthouse locations, each with its own probate office – file in whichever is more convenient.
Independence Courthouse – 168 North Edwards, Independence, CA 93526. (760) 872-3038. Hours: 8:30 a.m.–4:00 p.m., closed noon–1:00 p.m. Bishop Courthouse – 301 West Line Street, Bishop, CA 93514. (760) 872-3038. Hours: 8:30 a.m.–4:00 p.m., closed noon–1:00 p.m.
Step 1: figure out which path applies
California recently increased its small-estate thresholds substantially, so check this first – more estates now qualify to skip full probate than in past years.
Small Estate Affidavit (personal property) – for estates with personal property valued at $208,850 or less (for deaths on or after April 1, 2025; holds through March 31, 2028). No court filing needed – present the signed affidavit directly to the bank or institution holding the property. Must wait at least 40 days after the death, and no probate proceeding can already be pending.
Petition to Determine Succession to Real Property, Primary Residence – for a decedent’s primary California residence valued at $750,000 or less (Judicial Council Form DE-310). Requires a 40-day wait, notice to heirs, and a probate referee appraisal.
Affidavit for Real Property of Small Value – for other (non-primary-residence) California real property valued at $69,625 or less (Form DE-305). Requires a 6-month wait.
Formal Probate – required when the estate exceeds these thresholds. California typically uses the Independent Administration of Estates Act (IAEA), letting the personal representative handle most matters without a court hearing for each step.
California is a community property state – a surviving spouse already owns their half of community property, and can often use a simplified Spousal Property Petition (Form DE-221) instead.
If using the small estate affidavit (personal property)
Wait at least 40 days after the death.
Confirm total qualifying California personal property (excluding trust assets, joint tenancy, POD/TOD accounts, and beneficiary-designated accounts) is $208,850 or less, using date-of-death values.
Complete the affidavit under Probate Code § 13100.
Present it with a certified death certificate directly to the bank or institution – no court filing required. Collecting property this way makes you personally liable for the decedent’s unsecured debts up to the value received (Prob. Code § 13109).
IF USING THE PRIMARY RESIDENCE PETITION OR SMALL REAL PROPERTY AFFIDAVIT
Confirm the property qualifies and the applicable waiting period has passed (40 days for the primary-residence petition; 6 months for the small real property affidavit).
File the petition (Form DE-310) or affidavit (Form DE-305) with the Inyo County Superior Court, at either the Independence or Bishop courthouse.
A probate referee appraises the property; heirs receive notice.
Once approved, the property transfers without full probate administration.
If formal probate is required
Deliver the original will (if any) to the court clerk within 30 days of learning of the death (Prob. Code § 8200).
File a Petition for Probate (Form DE-111) to admit the will and request appointment as personal representative.
The court issues Letters Testamentary (Form DE-150) or Letters of Administration.
If Independent Administration authority is granted, the personal representative can act on most matters without separate court hearings.
Notice to creditors and an inventory/appraisal (with a probate referee) follow, along with payment of debts and taxes.
The estate closes with a final petition for distribution.
What it costs
Small estate affidavit / real property affidavits: no court filing fee for the personal-property affidavit; filing fees apply to the DE-310 primary-residence petition and DE-305 small real property affidavit.
Formal probate filing fee: several hundred dollars, varying somewhat by county.
Personal representative and attorney compensation: statutory fee schedule based on estate size (Prob. Code §§ 10800–10810) – a percentage that declines as the estate grows.
No California state estate tax or inheritance tax.
