When the Other Side Cannot Be Found
A case cannot move until the defendant has been given notice. When nobody knows where that person is, the court can allow a substitute for hand delivery, but only after being shown that a real search was made and failed.

The rule in short
When a defendant cannot be located, most courts permit service by publication, by posting, or by another method the judge designs, but only on a motion supported by a declaration of diligent search. Courts expect the last known address, the workplace, relatives, the postal service, voter and property records, and licensing databases to have been checked. Publication is the weakest form of notice, and a judgment resting on it is the easiest kind to reopen.
A defendant who cannot be found can still be sued, but only with a court order allowing something other than hand delivery. The order comes after a motion, and the motion has to be supported by a sworn account of a search that was made and failed. No search, no order.
The reason is constitutional rather than technical. Notice is what makes a judgment binding on someone who was not in the room. Courts therefore treat publication and posting as substitutes to be used when nothing better is available, and they read the supporting declaration with that in mind.
What a diligent search means
Diligence is measured by where the searcher looked, not by how long it took. Courts expect the obvious sources to have been checked and the results recorded: the last known residence, any workplace, relatives and known associates, the postal service for a forwarding address, and the telephone or utility record if one exists.
Public records add weight because they are verifiable. Property records show whether the person owns anything nearby. Voter registration and vehicle records list an address. State licensing registries list a business address for anyone who holds a trade license. Court files show whether the person has appeared in another case recently.
What courts do not accept is a single unanswered knock and an assertion that the person has vanished. A declaration should read like a log: date, source consulted, result. Where a professional skip trace was ordered, attach the report. The point is to let a judge see the shape of the effort rather than take a conclusion on trust.
Some sources are worth more than others because a judge can test them. A postal service response confirming no forwarding address is a document. A relative saying the person moved away is hearsay unless the declaration names the relative and quotes what was said. Where a search produced a possible address that was never tried, the declaration should explain why, because an untried lead is the first thing a defendant points to later.
Employment is the most productive line and the one most often skipped. A person who has disappeared from a residential address is frequently still working, still licensed, and still receiving mail somewhere. Checking the state's business and professional license registries, and any union or trade body, costs nothing and sometimes ends the search on the same afternoon it started.
Asking the court for permission
The motion is short. It identifies the defendant, describes the claim, recounts the attempts at personal and substituted service, attaches the declaration of diligence, and asks for a specific alternative. Naming the alternative matters: a judge is far more likely to sign an order that proposes publication in a named newspaper plus mailing to the last known address than one that asks for something unspecified.
Judges frequently order a combination. Publication alone, on its own, is the weakest notice available, so courts often add a mailing to every address on record, a posting at the property in a housing case, or electronic notice to an account proved to be active.
Timing is a live problem. Most systems set a deadline for serving the summons after filing, and the search plus the motion plus the publication period can outrun it. Ask for an extension of the service deadline in the same motion rather than discovering the expiry later.
Expect the motion to be refused at least once. Judges commonly send a first application back with a note that the search was thin, naming a source that was not consulted. That is a workable outcome: check the missing source, add it to the declaration, and file again. Treating the refusal as final, and abandoning the case, is the more expensive reading of it.
Publication is legally sufficient and practically useless. It rarely produces actual notice, it costs money, and it leaves a judgment that can be reopened. Where there is any live lead, spending another week and another service attempt on it is almost always cheaper than the publication route and the challenge that tends to follow it.
The alternatives a court can order
| Alternative | What the court needs first | Typical cost | Strength as notice |
|---|---|---|---|
| Publication in a newspaper | Declaration of diligent search and an order | Publication rates for several weeks | Weak |
| Posting at the property or courthouse | Order, usually in housing or property cases | Low, sometimes a server's fee | Weak to moderate |
| Mailing to a proved address | Evidence the address is current | Postage and certified mail | Moderate |
| Electronic notice by order | Proof the account is active and belongs to the defendant | Minimal | Moderate, often ordered as a supplement |
After the notice runs
Service by publication is complete a fixed period after the first or last insertion, depending on the state. The newspaper supplies an affidavit of publication, and that document goes into the court file the same way a server's affidavit would, following the pattern described in serving papers and proving you did.
Only then does the response clock start. If nothing is filed, the plaintiff can seek a default. Courts scrutinize a default built on publication more closely than an ordinary one, and some require a further declaration confirming that the defendant is not on active military service before judgment is entered.
Enforcement is where the weakness shows. A judgment obtained by publication can be attacked whenever the defendant learns of it, and courts hearing that challenge look first at whether the search was honest. A thin declaration filed to satisfy a clerk becomes, at that stage, the reason the judgment falls.
Cost and whether it is worth it
Publication is charged by the newspaper at a legal-notice rate and often runs to several times the filing fee. It is a court-ordered cost, so some courts will waive or advance it for a fee-waiver holder, while others treat it as a private expense outside the waiver. Where the amount is refused, the payment options in paying court fees when a waiver is refused can apply to the court's own portion.
Weigh the money against the outcome. A judgment against someone with no known address is difficult to collect, and the publication route adds cost at the start for an asset that may be hard to enforce and easy to reopen.
Court staff can point to the local rule, name the newspapers the court accepts, and identify the form. They cannot advise whether a particular search will be considered diligent, which is a legal judgment, and the boundary is described in what a court clerk may and may not tell you.
Points to carry away
- Alternative service requires a court order, not a decision by the person filing the case.
- A declaration of diligent search must list the specific places checked and what each one produced.
- Publication normally runs in a newspaper circulating where the defendant was last known to live, for a set number of weeks.
- Some courts allow posting at the courthouse or at the property, and a growing number permit electronic notice where a working address is proved.
- A default judgment obtained through publication is the most vulnerable kind, because the defendant may never have seen the notice.
Questions readers ask
How many attempts at personal service are enough before asking the court?
There is no single number, and courts look at quality rather than count. Three attempts on three consecutive weekday mornings at one address is weak. Three attempts at different times of day and on different days of the week, at two addresses, with a note of what the server observed, is strong. Many state rules simply require reasonable diligence and leave it to the judge. The declaration should show a search that a sensible person would recognize as genuine effort rather than box-ticking.
Can a defendant be served through a social media account or by email?
Sometimes, and only by court order. Judges in several states and federal districts have allowed electronic service where the moving party proved the account was current and actively used by the defendant, and where traditional methods had failed. Proof usually means recent activity, messages that were read, or a reply from the account. Courts remain cautious because an account can be dormant or belong to someone else. Electronic notice is generally allowed alongside publication rather than instead of it.
What happens if the defendant surfaces after a default judgment?
The defendant can ask the court to set the judgment aside. Where service was by publication, courts are noticeably more willing to reopen, because the whole point of the rule is that actual notice was unlikely. Time limits apply and vary widely, but many states run the clock from when the defendant learned of the judgment rather than from when it was entered. Assets seized in the meantime may have to be returned, so a judgment built on publication is a fragile asset.

Serving Papers and Proving You Did
Court papers must be delivered by an adult who is not a party, and the delivery must be recorded in a signed proof of service filed with the court. Personal service is handing the papers to the person. Substituted service leaves them with a competent adult at the home or workplace and then mails a copy. Service by mail requires the recipient's cooperation in most systems. Defective service can void a default judgment long after it is entered.
Objecting to a Subpoena Aimed at You
A person commanded to produce documents may serve a written objection before the earlier of the compliance date or the period set by rule, which suspends the duty to produce until a court orders otherwise. A motion to quash or modify asks the court to cancel or narrow the subpoena. Federal Rule of Civil Procedure 45 requires a court to quash a subpoena that allows unreasonable time, exceeds geographic limits, demands privileged material, or imposes undue burden.
Taking Testimony Before Trial
A deposition is oral testimony taken under oath before trial, on written notice to every other party, and recorded by an officer authorized to administer oaths. Federal Rule of Civil Procedure 30 limits a deposition to one day of seven hours and limits each side to ten depositions without leave of court. Objections are usually stated for the record and the answer is given anyway, with the judge ruling later if the passage is offered in evidence.
