Legal service of process is the foundation of a lawsuit. It ensures the defendant is properly notified and given a fair chance to respond. If service is flawed, the entire case can be thrown out.
Improper service violates due process, which means the defendant was not legally notified. This can result in delays, case dismissal, or even permanent invalidation.
Here’s how improper service can kill a case before it even starts.
1. A Motion to Quash Service Can Invalidate the Lawsuit
If a defendant wasn’t served properly, they can file a Motion to Quash Service, challenging its validity.
What happens when a Motion to Quash is filed?
The court reviews the service process to determine if it was legal.
If the process server violated any laws, the service is invalid.
The plaintiff must restart the process—wasting time and money.
If service was illegal, the case is put on hold until corrected—or dismissed if it isn’t fixed in time.
2. Default Judgments Can Be Overturned
If a lawsuit moves forward based on improper service, any default judgment can be challenged and reversed.
What is a default judgment?
If a defendant doesn’t respond, the court may rule in favor of the plaintiff automatically.
BUT if the defendant was never legally served, they can ask the court to vacate (undo) the judgment.
A plaintiff who wins by default can lose everything if service was faulty.
3. Missed Deadlines Can Result in Permanent Case Dismissal
Every lawsuit has a service deadline—if service is delayed due to errors, the case may be dismissed forever.
How deadlines impact improper service:
Many states require service within 30 to 120 days after filing a lawsuit.
If improper service is challenged, the plaintiff may run out of time to fix it.
If the deadline expires, the plaintiff may have to refile the entire case—if allowed at all.
A process server’s mistake could cost the plaintiff the right to sue forever.
4. Perjury & False Affidavits Can Lead to Criminal Charges
If a process server lies about completing service, the entire case can collapse—and they could face criminal prosecution.
False service affidavits can result in:
Felony perjury charges (up to 5 years in prison)
Fines up to $10,000
Permanent dismissal of the lawsuit due to fraud
If a court discovers that service was falsified, the case isn’t just dismissed—it can’t be refiled.
5. A Defendant Who Wasn’t Properly Served Can Ignore the Case
If service wasn’t legally completed, the defendant has no legal obligation to respond to the lawsuit.
A defendant can ignore the case if:
They were never personally served (in states that require it).
Papers were left with an unauthorized person.
The process server did not follow legal requirements (wrong location, wrong time, or trespassing).
A court cannot rule against a defendant who was never legally notified.
6. Courts May Sanction the Plaintiff for Abusing the Legal Process
If a plaintiff knowingly uses improper service to gain an advantage, they could be sanctioned by the court.
Sanctions for improper service include:
Case dismissal with prejudice (meaning it cannot be refiled).
Fines against the plaintiff or their attorney.
Attorney fees awarded to the defendant.
If a plaintiff or their lawyer tries to cheat the system, the court can punish them harshly.
7. Contempt of Court Charges for the Process Server
A judge can hold a process server in contempt for violating service rules, which can impact the case.
If a process server is found in contempt:
The service attempt is declared invalid.
The plaintiff must reattempt service, delaying the case.
The process server may be fined or jailed, making them unreliable for future cases.
A bad process server can ruin a case before it even starts.
Common Reasons Courts Dismiss Cases Due to Improper Service
Wrong Person Served – A roommate, relative, or coworker cannot always accept service.
Failure to Identify the Defendant – Some process servers don’t confirm identity, leading to challenges.
Leaving Papers in the Wrong Location – Some states require personal delivery, not leaving documents on a doorstep.
Falsified Affidavit of Service – If a process server lies about service, the case can be dismissed.
Missed Service Deadline – If service is not completed in time, the lawsuit may be permanently dismissed.
Violating State-Specific Laws – Some states have restrictions on Sunday or holiday service.
ANY of these errors can give the defendant grounds to challenge the case.
Final Takeaway: Improper Service = Case Dismissed
If legal service isn’t done correctly, the case can be delayed, dismissed, or even permanently invalidated.
How improper service leads to dismissal:
Motion to Quash Service – The case gets delayed or restarted.
Overturned Default Judgments – A win can be erased if service wasn’t valid.
Missed Filing Deadlines – If service is late, the lawsuit may be dismissed forever.
Criminal Charges for Perjury – If a process server lies, the case may collapse.
Legal Sanctions Against the Plaintiff – Courts punish improper service attempts.
Process Server Contempt of Court – The server’s misconduct can get the case thrown out.
