About Merced County
Merced County occupies a pivotal position in the San Joaquin Valley – geographically central, agriculturally productive, and increasingly significant as the home of the University of California’s newest campus. The county stretches from the valley floor’s intensively irrigated farmland east toward the Sierra Nevada foothills, with Highway 140 providing the most direct route from the valley to Yosemite National Park – making Merced the practical gateway city for one of the most visited national parks in the world.
UC Merced – the tenth and newest campus of the University of California system, which opened in 2005 – is the most consequential development in the county’s recent history. Located on a hillside east of the city of Merced, the campus was deliberately sited in the San Joaquin Valley to expand UC access to an inland region historically underserved by the university system. UC Merced has grown steadily to approximately 9,000 students and is projected to expand significantly in coming years. The campus’s research programs – particularly in environmental systems, engineering, and applied mathematics – are beginning to seed a technology and innovation ecosystem in a county long defined purely by agriculture.
Merced (the county seat, population ~86,000) is a classic Central Valley city – a railroad town that grew on agricultural processing and commerce, with a historic downtown along Main Street and the surrounding residential neighborhoods that reflect successive waves of immigrant communities who came to work the fields. The Castle Air Museum – located on the former Castle Air Force Base (closed 1995 under BRAC) – preserves an extraordinary collection of Cold War-era military aircraft in the high desert air that keeps them remarkably well-preserved. The base closure left a significant economic hole that the county has worked to fill through the Castle Commerce Center industrial park on the former base property.
The Merced River – which flows from Yosemite Valley through the foothills and across Merced County to the San Joaquin River – is one of California’s premier whitewater rivers in its upper reaches and a key irrigation source in its lower stretches.
Merced County’s agricultural economy produces dairy (one of California’s top dairy counties), almonds, sweet potatoes, poultry, and a wide range of specialty crops supported by irrigation from the San Joaquin River and its tributaries.
County government is a five-member Board of Supervisors with a County Executive Officer. Separately elected: Assessor-County Clerk-Recorder, Auditor-Controller, District Attorney, Sheriff-Coroner, and Treasurer-Tax Collector.

California’s Proposition 13 governs all Merced County property taxation. Your assessed value is set at the purchase price and rises no more than 2% per year until sold. The Merced County Assessor-County Clerk-Recorder (2222 M Street, Merced, 209-385-7631) determines all property values.
Bay Area migration and appreciation: Merced County has seen significant housing demand from Bay Area workers priced out of coastal markets – particularly those working remotely or commuting via the San Joaquin Valley rail corridor. This in-migration has driven appreciation well above the historical norm, meaning new buyers are paying taxes on current market values while long-term owners benefit from decades of 2% Prop 13 protection.
Supplemental Assessment: New buyers receive a supplemental tax bill 3-6 months after closing reflecting the jump from the prior owner’s Prop 13 base to the new purchase-year base. Plan for this in your closing budget.
Decline in Value (Prop 8) appeal: File with the Merced County Assessment Appeals Board (2222 M Street, Merced, 209-385-7631) between July 2 and November 30 if market value has fallen below your current assessed value.
Prop 19 – Agricultural land inheritance: Since February 2021, agricultural land inherited by children who do not occupy it as a primary residence now reassesses to full market value – with only a $1 million buffer above the parent’s assessed value. For Merced County dairy and almond farming families with long-held Prop 13 bases far below current farmland market values, this change has made succession planning urgent.
Williamson Act: Merced County agricultural land enrolled in the Williamson Act (agricultural preserve program) receives significantly reduced assessed values in exchange for a 10-year non-development commitment. Many Merced County farm parcels are under Williamson Act contracts – verify the contract status of any agricultural land in an estate, as cancellation can trigger substantial back taxes.
No California estate or inheritance tax.
OWNWELL CTA: Merced County’s Decline in Value appeal window is July 2–November 30. Agricultural families need urgent Prop 19 review – inherited farmland not occupied by heirs reassesses to market with only a $1M buffer. Williamson Act contract status affects both taxes and estate planning options. Supplemental bills arrive months after closing. Ownwell manages Prop 8 appeals with no upfront cost.

Courts & Legal
Courts & Legal
The Merced County Superior Court at 627 W. 21st Street, Merced (209-725-4100) handles all civil, criminal, family, and probate matters.

California probate for estates over $184,500 in assets requires formal court administration. Revocable living trusts are particularly important for agricultural families seeking to avoid probate on farm real estate and handle multi-parcel succession. Community property: full stepped-up basis at first spouse’s death.
Agricultural succession: Merced County’s dairy and almond farming families face the full spectrum of Central Valley agricultural estate challenges – Prop 19 reassessment risk, Williamson Act contract succession, water rights (both surface rights from irrigation districts and groundwater rights under SGMA), and the challenge of keeping multi-generational farming operations intact when heirs have diverse interests and locations.
UC Merced research community: As the campus grows, UC Merced faculty and researchers participating in UC’s retirement system (UCRP) and developing intellectual property through UC’s technology transfer program will increasingly be a planning constituency in Merced County.

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 Merced County Superior Court, at either the Merced or Los Banos location.
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.
