How to Find Someone for Service of Process

Filing a lawsuit is only half the battle. Before a court can rule on your case, the person you are suing has to be personally notified — and that means someone has to physically deliver the papers to them. What happens when you cannot find that person? Maybe they moved without leaving an address. Maybe they are deliberately hiding. Maybe you only ever knew them by a nickname or an old phone number.

This guide walks you through how professional process servers and skip tracers locate hard-to-find defendants for service of process. We will cover the databases and records used, when to bring in a private investigator, and what to do when the trail goes completely cold.

Why Locating the Defendant Matters So Much

A lawsuit cannot proceed against someone who has not been served. This is a core principle of due process: the law assumes you cannot be subjected to a judgment without first being given fair notice and an opportunity to respond. If you cannot locate the defendant, you cannot serve them, and your case stalls.

Worse, courts impose deadlines. In California, you generally have three years from the date a complaint is filed to serve the defendant. If you blow past that deadline, the court can dismiss your case for lack of prosecution. Time matters, and the longer someone has been off the grid, the harder it gets to track them down.

That is why skip tracing — the process of locating someone who has “skipped” town — is such a core service offered by professional process serving companies. A good skip trace can mean the difference between a successful judgment and a dismissed case.

What Is Skip Tracing?

Skip tracing is the art and science of finding people who do not want to be found, or who simply have not kept their information up to date. The term originated in the bail bonds industry but has expanded into debt collection, repossession, missing persons cases, and yes — process serving.

A skip tracer does not break the law to find people. They use a combination of public records, proprietary databases, social media, and good old-fashioned investigative work to piece together a current address. Done well, skip tracing is closer to research than detective work.

When you order skip tracing through Famous Legal Services, you typically provide whatever you know about the subject — their full name, any old addresses, phone numbers, employers, date of birth, or even just their relatives' names. The more data points you can offer, the faster a skip tracer can confirm an identity and lock onto a current location.

The Databases and Records Skip Tracers Use

Professional skip tracers have access to subscription databases that aggregate billions of public and commercial records. These are not consumer-grade search tools — they are credentialed platforms that require licensing and adherence to federal laws like the Driver's Privacy Protection Act (DPPA) and the Fair Credit Reporting Act (FCRA).

Public Records

Many of the records skip tracers rely on are technically available to anyone willing to dig. The challenge is that they are scattered across thousands of county, state, and federal agencies. Skip tracers pay for tools that aggregate them in one place. Useful public records include:

• County recorder filings — deeds, mortgages, liens, and grant of trust documents reveal property ownership history
• Court records — civil, criminal, family, and probate filings often list addresses, employers, and relatives
• Voter registration — in many jurisdictions, this is public and updated frequently
• Business filings — Secretary of State records for LLC and corporation officers, registered agents, and DBAs
• Marriage and divorce records — useful for confirming name changes
• Death records — rule out the wrong person or confirm someone has passed

DMV Records

DMV records are a common source for current addresses, but access is heavily restricted under the DPPA. A licensed investigator, process server, or law firm with a permissible legal purpose — like litigation — can request DMV data through approved channels. Random consumers cannot. Famous Legal Services accesses DMV information only when a permissible-purpose request is properly documented for a pending case.

Credit Header Data

One of the most powerful tools in professional skip tracing is the “credit header” — the top of a credit report containing names, addresses, and phone numbers, but not the financial details. Under the FCRA, credit headers can be accessed for permissible purposes including locating a debtor or party in litigation. Skip tracers use this through licensed data brokers to find the most recently reported address tied to a Social Security number.

Utility and Service Connections

When someone moves and opens a new utility account, that connection often shows up in commercial databases within weeks. Even without naming utility companies directly, aggregate data products surface new address activity. This is one of the most reliable signals that someone has actually relocated.

Social Media and Open-Source Intelligence

You would be surprised how many people are hiding from a process server while posting their location on Instagram. Skip tracers routinely check Facebook, Instagram, LinkedIn, X, TikTok, and even niche platforms for posts, check-ins, photos with identifiable backgrounds, and tagged friends or family. Workplaces, gyms, and favorite restaurants frequently come up in social media research.

None of this involves hacking or deception. It is simply careful review of what someone has chosen to make public.

When to Hire a Private Investigator

Skip tracing through a process serving company is usually the first step. It is fast, affordable, and resolves the majority of cases. But sometimes the trail is genuinely cold and a more intensive investigation is required. That is when a licensed private investigator (PI) becomes valuable.

You may want a PI when:

• The subject has deliberately changed their identity or is using aliases
• Witness interviews are needed to track recent movements
• Surveillance is required to confirm someone's actual residence versus a registered address
• The subject has fled the country or moved internationally
• The case involves fraud, hidden assets, or other elements where forensic work matters

A PI typically charges hourly and runs significantly more than a flat-fee skip trace. For most service of process cases, however, a thorough skip trace by a registered process server is enough to find the defendant. PIs are usually reserved for difficult or high-stakes matters.

What If You Still Cannot Find Them? Service by Publication

If every reasonable effort to locate the defendant has failed, California law provides a last-resort method of service called service by publication. Under California Code of Civil Procedure section 415.50, when a party cannot be served with reasonable diligence by any other method, the court may authorize publishing the summons in a newspaper of general circulation in the area where the defendant is most likely to be found.

Service by publication is not easy. It requires:

1. A motion to the court requesting permission to serve by publication
2. A detailed declaration of due diligence showing every step you took to find and serve the defendant — skip tracing, attempts at known addresses, attempts at relatives' homes, contact with employers, and so on
3. A court order authorizing publication
4. Four consecutive weeks of publication in an approved newspaper
5. A proof of publication filed with the court when finished

Courts scrutinize publication requests. If the judge believes you did not really try hard enough to find the defendant, the motion will be denied. That is one more reason a documented, thorough skip trace through a registered process server is worth the investment — it builds the diligence record you will need if you ever do have to go the publication route.

What Information Helps a Skip Tracer Most?

If you are about to hire a process server or skip tracer, gather as much of the following as possible before placing your order:

• Full legal name — first, middle, last, and any known maiden names or aliases
• Date of birth — even an approximate year helps
• Last known address — even if it is old
• Last known phone number — landline or mobile
• Last known employer
• Names of relatives or close friends
• Vehicle information — make, model, year, plate if known
• Social media handles or URLs
• The reason for service — some legal contexts unlock specific permissible-purpose searches

The more identifiers you provide, the easier it is to confirm you have located the right person. Common names like John Smith require additional data to narrow down which John Smith is yours.

Common Mistakes That Make Locating Someone Harder

People who try to skip trace on their own often run into the same problems:

Relying Only on Free Search Sites

Sites that advertise free people-search results often display data that is years out of date. Worse, they sometimes mix records for different people with similar names. Without access to credit headers, DMV data, and licensed databases, you are working with a fraction of the available information.

Calling and Tipping Them Off

If you find a phone number and call the person to confirm their address, you have just tipped them off. Many people who avoid service will go further underground the moment they realize a lawsuit is coming. Skip tracing is supposed to be quiet.

Not Documenting Attempts

If you do not document each attempt to locate and serve, you will not have the record needed to support a motion for substitute service, alternative service, or service by publication later. Date, time, address, and outcome of every attempt should be logged. For more on this, see our article on what substitute service of process is.

Waiting Too Long

California's three-year service deadline runs from the date the complaint is filed. People sometimes file a case and then sit on it for months hoping the defendant will surface. Meanwhile, the defendant has moved, changed phone numbers, and become harder to find. Start skip tracing immediately.

How Famous Legal Services Approaches Hard-to-Find Subjects

When you hire Famous Legal Services for a difficult service, our typical workflow is:

1. Initial skip trace using licensed databases — credit headers, public records, DMV (when permissible), and social media
2. Verification of the address through utility data, neighbor contact, or drive-by confirmation
3. Multiple attempts at different times of day to maximize the chance of personal service. Read about our approach in what a process server actually does.
4. Stake-out service when the subject is known to be evading. See our article on process server rules in California for what is and is not allowed.
5. Substitute or alternative service when personal service is not possible after diligent attempts
6. A documented declaration of due diligence if you ultimately need to seek service by publication

Every step is documented with GPS-verified records so your file is complete and your eventual proof of service or motion paperwork holds up in court.
