The whole file hangs on one address

A law firm sends papers to serve. The papers are complete on the law: they name the person and the court. They say very little about what a server needs to know to find that person. This article describes a use case.

What the papers do not say

Every service job depends on one address, and the papers often get it wrong. When a server cannot find the person, the firm turns to skip tracing: searching for a current address, then recording each attempt. That record may end up in a sworn affidavit. Yet the search itself often lives outside the job software, in notes and in memory.

The address on the papers is often months old. Since then, the person may have moved, changed jobs, or stopped picking up mail. People move a lot. The U.S. Census Bureau reports that the percentage of movers to a different residence in 2024 was 11.8 percent.

So the first address is a starting point, not an answer. Knowing how to find someone to serve papers is part of the job, and it takes time nobody sees.

The clock and the sworn record

The search runs against a deadline. For federal cases, Rule 4 of the Federal Rules of Civil Procedure sets it in plain terms:

“If a defendant is not served within 90 days after the complaint is filed, the court—on motion or on its own after notice to the plaintiff—must dismiss the action without prejudice against that defendant or order that service be made within a specified time.” — Federal Rules of Civil Procedure, Rule 4, Legal Information Institute

In short: under Rule 4, 90 days to serve, or the court steps in.

When the person cannot be found, the server does not just stop. Many states let a court allow another method, such as service by publication, but only after a sworn showing of a diligent search. A server may also file an affidavit of non-service, sometimes called a non est return, that lists each attempt. Either way, the quality of the search ends up in a sworn document.

The work is not the search, it is keeping track

What weighs on a firm is not running one search. It is everything after it:

• results that come back out of order, from different places that do not talk to each other;
• results that contradict each other, like two likely addresses, or an employer the person left long ago;
• empty results, which look just like a search that was never run, unless someone keeps the list;
• and a job that, all the while, is running against a deadline nobody has paused.

The job software holds the job, the papers and the invoice. It does not hold the search. The search lives in an inbox, in a spreadsheet on the side, and in the memory of whoever runs it. It goes on vacation when they do. Skip tracing software can return results. It does not decide what they mean for this job.

A job that has stalled has rarely stalled for lack of a legal route. It has stalled for lack of an answer nobody chased.

What the law limits, and why it matters here

Search data comes with rules. Federal and state privacy laws limit who may use some personal records, and for what purpose. A firm has to be able to say why it looked something up.

That limit sets the shape of what a tool may be inside a firm. A search record stays tied to its job and serves that job. It never becomes a reusable file on a person, carried from one case to the next. That is not an extra precaution we add. It is the starting point.

What an agent holds, and what it never touches

An agent keeps the list and the calendar: what was searched, what came back, and what is still missing. It compares new results with what the job already holds. When two versions do not match, it flags them instead of picking one.

What it does not do is just as easy to say. It does not judge whether the search was diligent enough. It does not write or sign the affidavit. It never serves papers. And it builds no file on anyone that outlives the job.

It is built to measure for one firm and installed at the firm’s office. The files stay on the firm’s own machines. Only the text a task needs is sent to the AI model.
