San Mateo County Court Information

You can file documents in person at the courthouse or electronically through an approved eFiling service provider. Through 1Court, our trusted partner Nationwide Legal can manage the entire process on your behalf ensuring every document is correctly formatted, court-compliant, and submitted on time. Whether your court supports eFiling or still requires in-person delivery, Nationwide Legal handles the full filing cycle and returns your stamped copies directly to you.

Most county courts handle civil, small claims, family, probate, and criminal matters. Each courthouse division may have its own filing requirements and deadlines. 1Court simplifies this by linking you to the right division and form set for your case. And if you need hands-on help, Nationwide Legal can prepare, assemble, and file your case materials accurately for any court division statewide.

Many California and partner-state courts now support eFiling for civil and probate cases. If this court offers eFiling, you can upload and submit instantly through 1Court’s connected network. If not, Nationwide Legal can physically deliver your documents to the clerk’s office ensuring same-day or next-day filing in counties without eFiling access. You’ll get digital proof of submission and return copies through your preferred system or email.

Turnaround time varies by court and document type typically 1–3 business days for eFilings and 3–5 days for physical filings. With Nationwide Legal, you don’t need to track court queues yourself: their filing team monitors court responses and sends your file-stamped copies directly to your inbox or case management system as soon as they’re accepted.

Most clerks accept filings from 8:00 a.m. to 4:00 p.m., Monday through Friday, excluding court holidays. eFiling portals remain open 24/7, but filings submitted after 11:59 p.m. are considered received the next business day. Nationwide Legal ensures every submission meets cutoff times whether by electronic upload or physical drop-off to avoid any late filing risks. Check your specifc court in our 1Court directory

Filing fees vary by case type, division, and county. You can view the latest fee schedule on the court’s official website or request a custom quote directly through Nationwide Legal when uploading your documents on 1Court.

Rejections are often caused by missing signatures, incorrect case numbers, or improper document formatting. Nationwide Legal’s trained reviewers check each filing for compliance before it ever reaches the court. If a rejection does occur, they correct and resubmit immediately, often within hours, so your case remains on track without added delays.
