For a paralegal tracking deadlines, Tustin is an easy city on paper. Nearly every kind of Tustin case ends up in one building, the Central Justice Center in Santa Ana, about 3.6 miles from the center of town. Only family law and probate leave Santa Ana, and both go to justice centers within about 7 miles.
The harder part is often the address itself. Tustin shares ZIP Codes with unincorporated North Tustin and with Santa Ana, and a large former Marine Corps air station inside the city is still being redeveloped into new neighborhoods. Both can trip up a server who's working from an old map or a mailing label.
So the most useful thing in a Tustin request is a precise address: street, unit, and whether it's in the city, in North Tustin or across the line in Santa Ana. The request is run from Sacramento, about 395 miles north, and the papers are served wherever that address puts them.
Tustin's courthouse assignments
The Orange County Superior Court assigns cases by type under its Court Designation List, effective June 30, 2025 (Local Rule 365). Tustin's row:
| Tustin case | Justice center | Straight line from central Tustin |
|---|---|---|
| Limited and unlimited civil | Central Justice Center, 700 Civic Center Drive West, Santa Ana | 3.6 mi |
| Small claims | Central Justice Center | 3.6 mi |
| Unlawful detainer (eviction) | Central Justice Center | 3.6 mi |
| Civil harassment restraining orders | Central Justice Center | 3.6 mi |
| Criminal and traffic | Central Justice Center | 3.6 mi |
| Family law and domestic violence | Lamoreaux Justice Center, 341 The City Drive South, Orange | 5.9 mi |
| Probate, mental health, elder abuse restraining orders | Costa Mesa Justice Complex, 3390 Harbor Boulevard | 6.7 mi |
| Complex civil | Civil Complex Center, 751 West Santa Ana Boulevard | Santa Ana |
The criminal and traffic line is what sets Tustin apart. The Central Justice Center's page lists Orange, Santa Ana, Tustin and Villa Park as the cities it serves for those matters. Neighboring Irvine sends its criminal and traffic cases to the Harbor Justice Center in Newport Beach, and Costa Mesa sends them to Westminster.
The Central Justice Center describes itself as a full-security building with weapons screening. It lists (657) 622-6878 for civil and small claims and (657) 622-8459 for criminal and traffic. Represented parties e-file; that requirement sits in a footnote to the designation matrix. We can handle the filing first and then the service, both on one request; see Orange County court filing.
Tustin Legacy: a former air base with new streets
The City of Tustin's history pages describe the base in detail. It began in 1942 as a Navy blimp station. It was reactivated in 1951 as a Marine Corps helicopter facility, which the city calls the country's first military airfield dedicated solely to helicopter operations. The base was annexed by the city on April 23, 1976, recommended for closure in 1991, and officially closed on July 3, 1999. Its hangars were entered into the National Register as a historic district in 1975.
The city has named the roughly 1,600-acre site Tustin Legacy and is guiding its reuse under the MCAS Tustin Specific Plan, with build-out expected over 20-plus years. For service, that means a part of Tustin where streets, buildings and addresses are newer than in the rest of the city. When the address is in a recently built complex:
- Give the building and unit, plus any leasing office or concierge desk.
- Add a cross street, in case a newer street isn't on every map.
- Say how residents get in, such as a fob, a call box or a garage gate.
- Include the person's schedule, since a gated building is easiest to reach when someone is coming or going.
North Tustin and the shared ZIP Codes
North Tustin is an unincorporated community governed by the county, not part of the city. Here's how the three Tustin ZIP Code areas divide, by land area, in the Census Bureau's 2020 ZCTA to place file:
- 92780 is about 87% City of Tustin and about 13% North Tustin.
- 92782 is about 99% Tustin, with a small piece of the City of Orange.
- 92705 is only about 5% Tustin by land area. About 49% is North Tustin, about 39% is Santa Ana, and a little is in Orange or outside any community.
- The city's own land is split almost evenly between 92780 and 92782, with about 5% in 92705.
So a 92705 address is more likely to be North Tustin or Santa Ana than the City of Tustin. For the courthouse, it makes no difference. For a city ordinance, a business license question or which police agency took a report, it does, and the parcel's assessor record is the place to check.
Papers to serve in Tustin?
Evictions and small claims at the Central Justice Center
Tustin evictions are filed in Santa Ana at the Central Justice Center, which also processes every small claims filing in the county.
For a Tustin rental, send every tenant's name as it appears on the summons, the unit and building, and gate or garage details. For a small claims defendant, the hearing date sets the deadline: at least 15 days' notice when the defendant lives in Orange County, at least 20 when they live elsewhere (CCP § 116.340). The claimant can't hand over the papers; another adult who isn't in the case does, then signs form SC-104.
From January 1, 2027, before papers are left with another adult at a home, diligence is shown by tries at personal delivery on at least three occasions, on three different days at three different times (CCP § 415.20(b)(2)). Our AB 747 guide explains the change, and our proof of service guide shows what the proof contains. We make no guarantees for service.
Hearing dates and the Santa Ana building
Since so much Tustin litigation runs through one courthouse, the details on the face of the papers are what separate one case from another. Before you send a request, check four things:
- The courthouse address on the summons or notice reads 700 Civic Center Drive West for a civil, small claims or eviction case, not the Lamoreaux or Costa Mesa address.
- The department number is filled in on any order to show cause or notice of hearing.
- The hearing date leaves enough time. A small claims defendant in Orange County needs 15 days; a restraining order has to be delivered before the hearing date printed on it.
- Every attachment the court requires is in the PDFs, so the server delivers one complete set.
If something looks off, sort it out with the clerk before service. Correcting a summons after it's been served usually means serving it again.
Subpoenas for Tustin criminal and civil cases
Because Tustin criminal cases are heard at the Central Justice Center, a Tustin witness may be subpoenaed to Santa Ana for a criminal hearing as well as a civil one. A subpoena that requires someone to appear is served by delivering it to the witness personally (CCP § 1987(a)). Give us the witness's home and work addresses and the appearance date, and say whether a witness fee check is included. Our post on serving a subpoena in California covers fees and timing.
Family law in Orange, probate in Costa Mesa
A Tustin divorce, custody, support or domestic violence case goes to the Lamoreaux Justice Center in Orange, about 6 miles north. Proof of a family law summons usually goes on FL-115; for a domestic violence order it's DV-200. The petitioner can't serve the other party personally.
Probate goes to Costa Mesa, about 6.7 miles southwest. We serve probate citations and notices at each listed person's address, in Tustin or elsewhere.
Serving a Tustin company
A receptionist, a store manager or a security desk usually can't accept service for a company. For a corporation or LLC, look up the agent for service of process on bizfile Online and send us the agent's name and address as listed (Corporations Code § 17701.13 for LLCs). When the listed agent is a national service company, our CSC and CT Corporation pages explain how those offices are served. Serving corporations covers the rest.
When the person or business has moved, skip tracing looks for a current address before the server goes out. Our post on finding a defendant in California lists what to gather first.
Sending a Tustin Service Request
Start a Service Request and attach up to 5 PDFs. Enter each name as the caption shows it, then each address with its true city, North Tustin and Santa Ana included, plus building, unit and gate notes. Pick Rush or Standard, and add a filing if the case still needs one. Every update comes by email. Questions can go to Service@ValproAttorneyServices.com or 855-582-5776.
