Which forms does every Contra Costa County case need?

The statewide ones, whatever the county adds. A complaint with at least one cause of action attached, and a Civil Case Cover Sheet, which is mandatory with the first paper in every California county.

Does the county decide where my case is filed?

No, the statute does. The superior court in the county where the injury happened is a proper court, and so is the county where a defendant lived when the action was filed. Local rules then govern how the case is filed and handled once it is in the right county.

Filing a civil case in Contra Costa County

Reviewed by Slick Nick, California licensed attorney · State Bar #324789 · Last updated September 1, 2026

Every California civil case is opened with the same statewide papers. What changes county by county is how they are filed and what the local court adds on top. This page covers the Superior Court of California, County of Contra Costa. It describes procedure; it does not tell you what to do, and it is not legal advice.

Electronic filing

E-filing is mandatory for represented parties in Contra Costa County. The civil division implemented mandatory electronic filing for attorneys, and offers e-filing as an option to self-represented litigants.

Mandatory from July 5, 2022.

If you are not represented: Self-represented litigants may e-file but are not required to.

The court cites the following as the authority for it:

Contra Costa County Local Rule 2.87
Ninth Amended E-Filing Standing Order

This matters to an injured person more than it looks. If you are represented, the requirement falls on your lawyer, not on you. If you are not, it is worth knowing whether the court will accept paper — because turning up with paper at a court that has stopped taking it costs a day.

Other things the court says

The court applied the change across unlimited civil, limited civil, complex civil, unlawful detainer, small claims and family law.

What is the same everywhere in California

Whatever a county adds, these do not change.

The Civil Case Cover Sheet, CM-010, is mandatory with the first paper. If it is missing or defective the clerk must still file the paper, but the party or the lawyer can be sanctioned.
The complaint is not complete without at least one cause of action attached.
In a personal injury or wrongful death case the amount demanded is not stated in the complaint.
A party under 18 needs a guardian ad litem appointed, and a settlement for them needs the court's approval.
Which county the case belongs in is set by statute, not by the county's own rules. Venue and the courthouses in Contra Costa County.

If a public entity is the defendant

Nothing on this page changes the six-month clock. A claim against a city, the county, or the state generally has to be presented to that entity within six months of the injury — which happens long before anything is filed in court at all. Claims against a government entity.

Start a case review call

On a case review call, I go through the facts with you: what happened, when, whether you were hurt, whether anyone represents you, and how to reach you. It is not legal advice, and I will not put a value on your claim.
