GPS-Stamped Proof of Service: What California's SPARE Act Requires

California's SPARE Act (AB 747) takes effect January 1, 2027. For covered types of service, it requires process servers to include photographs with a readable date, time, and location stamp in the proof of service. Process servers in California should prepare now, and other jurisdictions are considering similar rules.

What Sewer Service Is, and Why It Became a Problem

The term sewer service refers to a process server falsely claiming that documents were delivered when they were not, sometimes by discarding the papers entirely rather than making an actual attempt. When this happens, a lawsuit can proceed without the defendant ever knowing about it, often ending in a default judgment, a garnished paycheck, or a drained bank account years later. Consumer debt cases and eviction proceedings have been particularly affected, since defendants in those cases are often the least equipped to catch and challenge a bad service before a default judgment is entered.

Courts and lawmakers have known about this problem for years, but proving it happened has always been difficult. A signed declaration is hard to contradict after the fact, especially when the defendant has no documentation of their own showing they were never approached.

California's SPARE Act Changes the Standard

California addressed this directly with the SPARE Act, short for Service of Process Accountability, Reform, and Equity, passed as Assembly Bill 747. The law takes effect January 1, 2027, and it changes proof of service in a few concrete ways.

Under AB 747, the proof of service must include one or more photographs of the site of each completed or attempted service. Each photo must carry a readable stamp that automatically records the date, time, and GPS or equivalent coordinates, and it must be taken as closely as practicable to the time of service or attempt. For a dwelling or place of business, at least one photo must show the door, or the entrance if the door is not reasonably accessible. A server who photographs an entrance instead must explain with specificity why the door was not accessible. The photo requirement covers specified personal and substituted service, and covered posting in unlawful detainer cases. The law also addresses reasonable diligence before a server can move to substituted service. Confirm the current diligence requirements for your case type in the statute itself, because the required number and timing of attempts depend on the kind of action. There are two separate exceptions. If no GPS or cellular signal is available, the server must include a detailed statement explaining why the photo lacks a readable location stamp. If taking a photo would compromise the server's safety, the photo itself is not required, but the server must document why.

The burden of proof is also changing. Under the new section 473.2 procedure added by AB 747 and amended by AB 2042, a party seeking relief from a default must first offer evidence, by sworn affidavit or otherwise, that service was not lawfully effected. The party seeking the default must then prove by a preponderance of the evidence that service was lawful. Section 473.2 applies to service attempted or completed on or after January 1, 2027, and it does not set its own deadline.

Deadlines depend on which procedure applies, so do not treat them as interchangeable. A motion to vacate a default judgment that is void for lack of proper service may be brought at any time under section 473(e). Separately, certain debt buyer default motions under Civil Code section 1788.61 must be filed within a reasonable time and no later than the earlier of six years after the default or 180 days after first actual notice. For identity theft or mistaken identity, the limit is 180 days after first actual notice, with no six-year outside limit. A challenge does not succeed automatically, so a server's documentation still matters.

Other States and Jurisdictions Are Watching California Closely

California is currently the clearest example of a state writing GPS-stamped proof of service directly into law, but it's unlikely to be the last. Sewer service and default judgments obtained through improper notice are not problems unique to any one state, and consumer protection advocates elsewhere have raised similar concerns for years. When one state passes reform legislation like the SPARE Act and it withstands scrutiny, other legislatures and even individual county courts often use it as a model rather than starting from scratch.

New York City already has its own process server rules requiring electronic records of service and attempted service that include GPS information, made shortly after the attempt. Its system differs from California's photograph rules, but GPS accountability in process serving is not limited to California. Requirements change, so confirm the rules for each jurisdiction where you serve. But the broader trend is worth watching. As courts and lawmakers around the country continue to focus on due process protections and fraudulent service, more states and local jurisdictions following California's lead over the next several years is a reasonable expectation, even if the specifics and timelines will vary from place to place.

What This Means for Process Servers Today

Even outside of California, there's a practical argument for adopting GPS-stamped documentation now rather than waiting for a law to require it. A proof of service backed by a time-stamped, geotagged photograph is simply harder to challenge than one backed by a signature alone, regardless of what a particular state currently mandates. Attorneys reviewing vendor relationships are already asking process serving companies how they document attempts, and servers who can answer that question clearly tend to have an edge.

This is part of why more investigators and process servers have moved toward documentation platforms that preserve photos, GPS data, and timestamps together as a case unfolds, rather than assembling that information after the fact. Modern documentation platforms such as Final Exhibit help process servers and investigators keep this kind of evidence organized from the moment it's imported, which matters if a proof of service is ever challenged months or years later.

The Bottom Line

California's SPARE Act represents the clearest legislative move yet toward requiring photographic, GPS-verified proof of service, and it takes effect January 1, 2027. New York City already has its own electronic service-record rules, and California's approach is likely to influence lawmakers elsewhere as due process and fraudulent service concerns continue to draw attention nationally. Process servers who build strong documentation habits now, regardless of what their jurisdiction currently requires, will be better positioned as more places begin to move in California's direction.
