In federal court, a constable or other process server has 90 days from the date the complaint is filed to deliver the papers. State courts set their own deadlines, and many fall in the 30-to-120-day range depending on the case type. So the honest answer to how long a constable has to serve someone is: the court sets an outer limit, but how fast the papers actually go out depends on the constable’s caseload, how findable the person is, and whether you handed over a good address.1Legal Information Institute.

The Federal 90-Day Deadline
Federal Rule of Civil Procedure 4(m) draws a hard line. If the defendant is not served within 90 days after the complaint is filed, the court must either dismiss the action without prejudice or set a new deadline for service.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons “Without prejudice” means you can refile, but refiling means new filing fees, a new case number, and a fresh clock.
There is an escape valve. If the plaintiff shows “good cause” for the delay, the court must grant more time. Good cause can include a defendant who is actively dodging service, a defect in attempted service that the plaintiff tried in good faith to correct, or a situation where the statute of limitations would bar a refiled action.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Even without good cause, the court has discretion to extend rather than dismiss. Don’t bank on that generosity. Treat the 90 days as real.
One trap catches people off guard. A dismissal without prejudice does not pause the statute of limitations. If the limitations period expires while your case sits unserved, the dismissal effectively ends the claim. The right to refile is worthless once there is no time left to file.
How State Court Deadlines Compare
State courts are not bound by the federal 90-day rule and write their own timelines. Many land somewhere in the 30-to-120-day range, though the specifics depend on the document type and the local rules. Some states measure the deadline from when the summons is issued rather than when the complaint is filed, which can shift the window by a few days depending on how quickly the clerk processes paperwork.
Urgent matters compress these windows sharply. A temporary restraining order or emergency protective order may need to be served within just a few days, because the court has already scheduled a hearing on the assumption the other side will have notice by then. Eviction cases in many jurisdictions also run on shortened service windows. The deadline that really matters is the one printed on the court papers themselves, often called the “return date.” That is the date the court expects to hear whether service happened.
What Slows a Constable Down
The biggest variable is whether the person can be found. With a solid address and a target who keeps regular hours, a constable may complete service on the first visit. If the recipient has moved, works irregular shifts, or is simply never home when the constable knocks, service stretches across multiple attempts on different days and at different times. Some constable offices make three to five attempts before returning the papers unserved.
Caseload is the other factor you cannot control. Unlike a private process server who gets paid per job, a constable is a salaried public employee working through a queue of service requests. During busy stretches, such as eviction surges, your paperwork may sit for days before anyone picks it up.
Accurate information helps. Giving the constable the wrong apartment number or a stale workplace address burns one of those limited attempts and pushes everything back. Geography and timing restrictions add friction too. Service in rural areas means longer drive times between visits. Many jurisdictions limit service to certain hours and prohibit it on Sundays and legal holidays, which narrows the available windows. A Friday afternoon filing with a Monday return date leaves almost no room for error.
What Happens If the Deadline Passes
When service does not happen in time, the case stalls. The court cannot exercise authority over a defendant who has not been properly notified. At that point, the plaintiff generally has two options: ask for more time or try a different approach.
Requesting an alias summons, which is essentially a reissued summons, restarts the service clock. It is a routine filing, not an emergency motion, but it has to happen before the original deadline expires or shortly after. If the plaintiff does nothing and the deadline lapses in federal court, the judge can dismiss the case on the court’s own initiative after giving the plaintiff notice.1Legal Information Institute.

The worst case is a dismissal that lands after the statute of limitations has already run. The dismissal is technically without prejudice, but the plaintiff cannot refile a time-barred claim. A without-prejudice dismissal does not give you any rights beyond what you already had. It puts you back in the position you were in before you filed. For claims with short limitations periods, every week of delay in service is a week of risk.
When a Private Process Server Makes Sense
Under federal rules, any person at least 18 years old and not a party to the case can serve a summons and complaint.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Most states follow the same approach, though a handful still require or strongly prefer law enforcement service for certain document types, such as serving someone inside a jail or prison.
The tradeoff is cost, speed, and communication. Constables and sheriffs typically charge a statutory fee set by the jurisdiction, often in the $30 to $90 range for standard service plus mileage. Private process servers generally cost more, often $50 to $150 or higher, but they work on a per-job basis, which creates a financial incentive to move quickly. A constable’s office may take days to make a first attempt. A private server advertising same-day service usually means it.
Communication differs too. A private process server will usually give real-time updates and answer status questions. A constable’s office handling hundreds of cases is more likely to offer a brief update or tell you to check back later. If you are working against a tight deadline, that transparency can be worth the extra cost. Some jurisdictions and some court orders specifically require service by a sheriff, marshal, or constable, so check your papers before switching.
When the Person Cannot Be Found
If a constable has made repeated, genuine efforts to serve someone and failed, the plaintiff can ask the court for permission to use an alternative method. Courts do not grant this lightly. You have to show that standard personal service has been attempted with real diligence and that the proposed alternative is reasonably likely to actually reach the person.
Common alternatives include posting the documents on the front door of the person’s last known address and mailing a copy to the same place, publishing a legal notice in a newspaper when the person’s location is completely unknown, and sending papers by certified mail with return receipt. In recent years, some federal courts have authorized service by email or social media when the defendant operates primarily online or has been communicating through those channels. Courts have approved service via Facebook and Twitter in cases where the plaintiff showed that electronic contact was the only realistic way to reach the defendant. These orders remain the exception and require a specific court order each time.
Every alternative method requires court approval first. You file a motion, show what you already tried, and explain why the proposed method is likely to work. A court will not approve publication service, for example, if the plaintiff has a current email address and has not tried using it.2Legal Information Institute.
