Process Server in Ontario, CA
187,000 residents, a massive logistics economy, and Southern California's largest master-planned community — served fast from 20 miles up the 10.
Ontario is the Inland Empire's front door — 187,000 residents, Ontario International Airport, and one of the largest logistics economies in the country, with roughly 120 million square feet of industrial space and hundreds of distribution operations. That mix makes Ontario serves distinctive: corporate and registered-agent serves at business parks by day, residential serves in fast-growing Ontario Ranch by evening.
We cover all of it from our West Covina office, about 25 minutes west on I-10 — close enough for same-day attempts, far enough that most LA-based servers charge you a premium to bother. Ontario Ranch alone spans 13 square miles of new neighborhoods, and we track its ever-changing streets so your serve doesn't die to a GPS gap.
Business serves, evictions, and evasive defendants — documented with photos and GPS on every attempt.
Where Ontario Cases Are Filed
Heads up — Ontario has no courthouse of its own. Many websites get this wrong. In San Bernardino County's current system:
Evictions (limited UD) & small claims: Fontana District — 17780 Arrow Blvd, Fontana, CA 92335
Criminal: Rancho Cucamonga District — 8303 Haven Ave, Rancho Cucamonga, CA 91730
Family law & unlimited landlord-tenant: San Bernardino District courthouses
Filing assignments can change — confirm with the court's "Where Can I File?" locator, or just ask us when you place your order.
