Inside Contra Costa County
What the data looks like here.Every month Contra Costa County hands us roughly 216 new pre-probate and inheritance data records, and 206 on average over the last twelve months. Those records come from death and property files, not a court docket, so they reach you without waiting for a probate case.
Why investors work Contra Costa County
California puts a recurring cost in front of an heir before any sale decision. Under Proposition 19, a parent to child transfer keeps the old Proposition 13 assessed value only if the home was the transferor's residence and the heir moves in and claims the exemption within a year; rent it out or skip the claim and the parcel resets to market value. On a house held since the 1970s that can mean several times the tax the year it changes hands. Contra Costa grew its older stock in distinct waves, from the blocks around Henry Kaiser's four Richmond shipyards to the Mount Diablo coal towns of Nortonville and Somersville that emptied when the mines closed. A living trust or a recorded transfer on death deed can move one of those houses with no ordinary probate case.
On the ground
Mount Diablo sits inside Contra Costa, and the mountain is a dividing line outsiders tend to underestimate. Its summit was fixed in 1851 as the initial point for federal land surveys covering most of Northern California and all of Nevada, so lot lines across the county still run back to that one rock. West of it, Henry Kaiser's four Richmond yards became the most significant shipbuilding operation on the West Coast, and the worker housing still fills the flat blocks behind the docks. East of it, the coal towns of Nortonville and Somersville are gone, and the county historical society points to Welsh inscriptions on the miners' gravestones. Pricing a Richmond bungalow and an Antioch ranch as one market is the mistake to avoid.
Comparing Probate Lead Sources in Contra Costa County
Contra Costa probate matters go to the Probate Division of the Superior Court of California, County of Contra Costa, which hears them in its general probate departments. Attorney e-filing runs through court-approved providers under the court's Local Rule 2.87, while self-represented parties may still file on paper. Once a case is opened, the register of actions appears on the court's Public Portal, though documents and orders are not online and take a records request. California gives a creditor four months from the issuance of letters to file a claim, so a filed estate often sits in court for months before it can distribute or sell anything. That register is useful, but it starts only after someone files, and any competing investor can pull the same names from the same portal. USLeadList instead builds this county's file from death and property records, typically about five weeks after a death, without waiting for that filing and independent of whether a case ever opens, and sells it to at most three subscribers.
How California rules shape Contra Costa leads
Verified state research, applied locally.Proposition 19, operative for intergenerational transfers on February 16, 2021 and implemented by Rev. and Tax. Code 63.2, attaches a real recurring cost to holding. A parent to child or grandparent to grandchild transfer keeps the Proposition 13 assessed value only if the property was the transferor's family home and the heir makes it their own principal residence and claims the homeowners' or disabled veterans' exemption within one year of the transfer. The exclusion is capped at the existing taxable value plus $1,000,000 as adjusted, which is $1,044,586 for transfers from February 16, 2025 through February 15, 2027. An heir who rents the home, leaves it vacant or does not move in loses the exclusion and the parcel is reassessed to market value, so a house held since the 1970s can carry several times the tax the day it transfers.
Ways property can avoid probate
Revocable living trust, the dominant instrument in California, and the revocable transfer on death deed under Prob. Code 5600 through 5698, which remains authorized until that part is repealed on January 1, 2032. Joint tenancy and community property with right of survivorship also move real property at death. Property passing by any of these routes never generates a probate filing.
Small-estate route
For deaths on or after April 1, 2025 there are three distinct routes, and they must not be collapsed into one court status. First, the Probate Code 13100 and 13101 affidavit can collect personal property after 40 days where the qualifying California estate does not exceed $208,850. It is furnished directly to the person, company or financial institution holding the property, is a non-court personal-property procedure, and cannot transfer a house. Second, the Probate Code 13200 affidavit for California real property of small value up to $69,625 is filed in the superior court and cannot be filed until six months after death. Third, the Probate Code 13151 procedure for a decedent's California primary residence up to $750,000 requires 40 days and a petition in superior court for an order determining succession, as amended by AB 2016, Stats. 2024, chapter 331. The amounts adjust every three years under Probate Code 890, next on April 1, 2028.
Timing that affects the public record
A creditor must file a claim before the later of four months after letters are first issued to a general personal representative, or 60 days after notice of administration is mailed or personally delivered to that creditor (Prob. Code 9100). Notice of the petition to administer the estate must be published three times, with first publication at least 15 days before the hearing and at least five days between the first and last publication dates (Prob. Code 8121). The personal-property affidavit under Probate Code 13100 and the primary-residence petition under 13151 require 40 days after death, while the real-property affidavit under 13200 cannot be filed until six months after death. The personal representative must petition for final distribution or report the status of administration within one year after letters issue, or 18 months where a federal estate tax return is required (Prob. Code 12200). No California judiciary source publishes a typical duration.
Where court cases can be checked
No statewide case search. Each of the 58 superior courts runs its own public case access portal, and the Judicial Council directs the public to the individual court through its Find Your Court locator rather than to a central index.
Why pre-probate
Why pre-probate leads in Contra Costa County, California?A public probate list requires a filed case. Our source does not require a filing and may precede a later filing, but that is not guaranteed.
Inheritance creates a property decision
A death does not guarantee a sale. It does create practical decisions about upkeep, distance, taxes, repairs and whether anyone in the family wants the property.
Earlier than a court filing
When probate is required, the public case begins after the death and after someone files. Our county records begin with the death record itself.
Not limited to probate cases
Trusts, survivorship ownership and state-specific transfer instruments can move a property without an ordinary probate case. Court-only lists do not identify those paths.
Property data with optional contact enrichment
Size, location, value, and tax information come with the property record. Phone, email, spouse, and relative data are available through the skip tracing add-on.
What we mean by pre-probate
Pre-probate > probate. Here's why.Our Contra Costa County data is not a court probate list. It identifies inherited-property records from deaths, including properties that may later enter probate and properties that never do.
The court docket is only one transfer path.
A trust, survivorship ownership or an authorized transfer deed may keep a property out of an ordinary probate case. The exact rules vary by state, which is why the local court and transfer details above matter.
An inheritance creates choices, not a guaranteed sale:
- Keep or occupy the property
- Rent it or transfer it within the family
- Sell it privately or through a public listing
