Poorest example of legal process servers I’ve EVER seen in 30 years of legal work. On top of it they’re crooks and illegally charged my card without my permission. I had used when originally hiring them 5 months prior. If ZERO stars was an option I would have selected it!!

How a Walnut order is worked
After intake, a registered process server takes the assignment with the address details and any access notes. Hillside addresses around Pierre Road and Snow Creek may need longer attempt windows; the server documents what was observed at each visit, and the signed proof of service is finalized when the matter resolves.

Frequently Asked Questions
Where do Walnut civil cases get filed?
Civil cases out of Walnut split by case type. Unlimited civil routes to the Stanley Mosk Courthouse downtown; limited civil, small claims, family, and traffic file at the East District courthouse in Pomona. Federal matters route to the Central District’s Western Division.
Can a server reach a recipient at Mt. SAC?
Service at a college campus may require additional coordination. Recipient handoffs at Mt. SAC typically happen at parking lots and building entrances during class hours; include the recipient’s department and any access information at intake.
How is service handled in Walnut hillside neighborhoods?
Hillside addresses around Pierre Road and Snow Creek include longer driveways and varied road frontage. The server documents what was observed at each visit and approaches the residence per the address details.
Not everyone at a Walnut address can legally take papers for someone else. At a hillside home off Pierre Road or an office along Valley Boulevard, the server may hand documents to a competent adult in the household or a person apparently in charge, but a young child or a random visitor will not do. See who is allowed to accept service of process on another person’s behalf.
Can a server work commercial addresses along Grand Avenue?
Commercial addresses along Grand Avenue and Valley Boulevard are reachable during business hours. Suite numbers and a brief description of the recipient help the server locate the right office.
How fast can service in Walnut typically be completed?
Most orders see a first attempt within a few business days. Faster turnaround can be requested at order time, with timing depending on the address and the recipient.
Can address verification be added to a Walnut order?
Yes. Address verification can be added before the assignment goes out when the address is uncertain. The check covers public records, and the result is logged to the order.
I had an exceptional experience with On-Call Legal Process Servers. They were incredibly reliable and efficient, especially when I needed rush service over the weekend. Their website was very user-friendly, providing clear fee information, and their outstanding customer service further boosted my confidence in their services, which made them an easy choice out of the many process server companies I looked into. Thanks to their prompt delivery, the served party contacted me shortly afterward to settle the case. Given their extensive coverage beyond Los Angeles, I plan to use them again soon for a small claims case in Riverside County.
I had to file a Writ of Review with the California Court of Appeal. I contact several services for assistances most were not interested and others didn't provide the services I needed. I called On-Call Legal Process Servers and spoke to one of their staff. The staff member gave me a list of services they provide everything from a small claims court, to Court of Appeal to the Supreme Court. They will assist you in the filing all court documents and proof of service. To get start with On-Call Legal Process Servers and more an account has to be opened online. Before charges can be posted to the account an Email is sent out listing the proposed charges. The staff returns Email questions and orders during their normal business hours during the same day. On-Call Legal Process Servers file the writ for me and obtain the filing court's case number.
I was fortunate enough to be introduced to On-Call Legal through a family friend for services of process. Not only were the owners Brandon & David incredibly kind, but their process servers were professional, fast and affordable. I would use them again and would recommend them to anyone.
On-Call was absolutely AMAZING! Our trial team at Brown Goldstein & Levy flew into LA for a USDC trial from Baltimore. From first contact, On-Call was professional, prompt & handled everything we threw at them from exhibit binders for the Court and parties, to delivery to Court to meet our 8:30 am filing deadline! David A & his team handled everything! Looking forward to working with them again!
