Vallejo is the most populous city in Solano County, yet its civil lawsuits are filed in another city. The county seat, Fairfield, holds the civil, family and probate counters. Vallejo's own courthouse handles criminal and traffic work. Valpro Attorney Services handles both ends of a Vallejo case from our Sacramento office: serving papers in Vallejo and filing them in Fairfield. We have no office in Vallejo.

Which court handles a Vallejo civil, small claims or eviction case?
The Old Solano Courthouse at 580 Texas Street in Fairfield. The court tags that building for civil, small claims and unlawful detainer cases, and the Civil Division gives it as the only civil address. A Vallejo landlord, creditor or small claims plaintiff files there, about 15.5 miles from the center of Vallejo in a straight line.

What happens at the Vallejo courthouse on Tuolumne Street?
The Vallejo Courthouse, in the Solano Justice Building at 321 Tuolumne Street, is a branch for criminal and traffic cases. The Criminal and Traffic Division pages each list a Vallejo branch beside Fairfield. Its location page says clerk's offices take drop-ins from 8 to 11:30 a.m. and appointments from 8 a.m. to 3 p.m.
The building sits on the west side of Tuolumne Street, with Virginia Street as the nearest cross street. SolTrans Route 4 runs there from the Vallejo Transit Center. The court's criminal page says fines can be paid at either the Fairfield or the Vallejo window, and each building has a drop box open 8 a.m. to 5 p.m.
For a civil matter, none of that helps. A complaint, an answer or a proof of service in a Vallejo eviction still has to reach Fairfield, on paper or through e-filing.
How does e-filing work for Vallejo cases?
Solano Local Rule 20 has made e-filing mandatory for attorneys in civil, family and probate cases since January 2, 2025. The court accepts e-filing in every case type except criminal, traffic and juvenile. Lawyers handling a Vallejo civil case can file without the drive to Fairfield. People without a lawyer may still file in person or by mail.
The same rule covers service between parties, with one carve-out that matters here. The court's page says documents are filed and served electronically "except when personal service is required by statute or rule." A summons, a small claims claim or an eviction complaint still has to be put in the defendant's hands, or served by another method the Code of Civil Procedure allows.
After an e-filing is submitted, a clerk reviews it, and the acceptance email carries a link to the file-stamped copy. Our Solano County court filing page and the court filings overview cover what we need to file for you.
Papers to serve in Vallejo?
Vallejo addresses and the county lines around them
Vallejo had 126,090 residents in the 2020 Census and an estimated 123,287 on July 1, 2025 (Census Vintage 2025). The city covers 4 Census ZIP Code areas: 94589, 94590, 94591 and 94592. Census ZIP Code areas follow mail delivery, not city boundaries, so check the city name on every address.
Three counties meet near Vallejo, and that changes which court a neighbor's case belongs to:
- Solano County: Vallejo itself and Benicia, 6.3 miles east.
- Napa County: American Canyon, 5 miles north, and the city of Napa beyond it.
- Contra Costa County: Crockett and Hercules across the Carquinez Strait, along with Rodeo and Port Costa.
Where a lawsuit is filed is a venue decision for you or your attorney. Serving the papers is a different step. We serve at the address you give us, whichever county court issued the summons.
What to put in a Vallejo Letter of Instruction
The Letter of Instruction gives the server what a street address can't. Good details for Vallejo addresses include:
- Unit and building. Apartment complexes need the building number or letter as well as the unit.
- Work schedule. If the person commutes, early mornings or evenings may be the only window.
- A second location. A job site, a gym or a relative's home nearby.
- Access. Gate codes, buzzer names and which entrance the person uses.
- Past attempts. If you or another server already tried, say when and what you learned.
Tell us the hearing date or response deadline that drives the job, and choose Rush or Standard. Both are described on this page. We make no guarantees for service.
Who can serve papers in Vallejo, and what changes in 2027?
Any adult who is at least 18 and not a party to the case may serve a California summons (CCP § 414.10). A Vallejo landlord or small claims plaintiff can't serve the other side personally, but a process server can.
Starting January 1, 2027, AB 747 tightens the rules for substituted service. Before papers can be left with someone else, diligence is shown by attempts on at least 3 occasions, on 3 different days at 3 different times (CCP § 415.20(b)(2)). The proof will need photos with date, time and GPS stamps (CCP § 417.10(a)(1)). See our AB 747 guide for what changes. This is general information, not legal advice.
Serving a Vallejo business
A storefront, a medical office or a warehouse in Vallejo may be run by a corporation or LLC. The person at the front desk may have no authority to accept service for it. Look up the entity on the Secretary of State's bizfile Online search and find its agent for service of process.
The law requires corporations to name that agent in their statement of information (Corporations Code § 1502(b)) and LLCs to maintain one (Corporations Code § 17701.13). Send the agent's name and address with the papers. If the agent is a person at a Vallejo address, we serve them there. Our serving corporations guide covers officers and out-of-state companies.
If the Vallejo address doesn't pan out
People move, and old addresses linger in court files. If the server finds a new tenant or an empty unit, ask about investigations and skip tracing. We look for a current address, report what we find and, once you approve, send the papers back out to that address.
The blog post Who Can Serve Court Papers in California? covers the rules on servers in more detail. For copies of filed papers, see document retrieval.
