Florida’s Chapter 48 governs jurisdiction and service of process: it tells courts when they have authority over a defendant, and it tells plaintiffs exactly how legal papers must be delivered to bring that defendant into a case. Get either wrong and the lawsuit can be dismissed, or a judgment already entered can be undone years later. The chapter matters most in two situations: suing someone who lives outside Florida, and making sure the summons and complaint reach the defendant in a way the court will accept.
What Chapter 48 Actually Controls
Two separate questions run through the chapter. The first is whether a Florida court has personal jurisdiction over the defendant, meaning a legally recognized basis for exercising authority over that person. The second is whether the defendant received formal notice of the lawsuit through a method the statute allows.
Both must be satisfied. A court with jurisdiction but defective service has no power to enter a valid judgment. A court with perfect service but no jurisdiction is in the same position. For Florida residents served in Florida, jurisdiction is usually straightforward and the fight is over service. For out-of-state defendants, jurisdiction itself becomes the battleground, and Section 48.193 is where that fight happens.
Reaching Nonresidents: Florida’s Long-Arm Statute
Section 48.193 is the mechanism that lets Florida courts hear cases against people and businesses that are not physically present in the state. It creates two categories, each with a different reach.
Florida courts apply a two-step analysis from Venetian Salami Co. v. Parthenais. First, do the plaintiff’s allegations fit within the long-arm statute? Second, does the defendant have enough minimum contacts with Florida to satisfy constitutional due process under International Shoe Co. v. Washington?1Justia. International Shoe Co. v. Washington Both steps must be passed independently. Meeting the statute does not automatically satisfy the Constitution.2Supreme Court of Florida. William J. Mitchell v. David W. Race
Specific Jurisdiction Under Section 48.193(1)
A nonresident who performs certain acts connected to Florida can be sued here for claims arising from those specific acts. The statute lists nine categories:
- Operating a business, business venture, office, or agency in Florida.
- Committing a tort within the state.
- Owning, using, possessing, or holding a mortgage or lien on Florida real property.
- Contracting to insure a person, property, or risk located in Florida.
- Maintaining a marital home in Florida at the time an alimony, child support, or property division action begins.
- Causing injury to people or property in Florida from out-of-state conduct, if the defendant was soliciting business here or if their products were consumed here in the ordinary course of commerce.
- Breaching a contract by failing to perform obligations that were required to be performed in Florida.
- Engaging in sexual intercourse within Florida from which a child may have been conceived, for paternity actions.
- Entering a contract that designates Florida as the forum under Section 685.102.
The key limit: the lawsuit must arise from the particular act listed. A nonresident who once did business in Florida cannot be sued here for an unrelated claim on that basis alone.3The Florida Legislature. Florida Statutes 48.193 – Acts Subjecting Person to Jurisdiction of Courts of State
General Jurisdiction Under Section 48.193(2)
The broader category. A defendant engaged in “substantial and not isolated activity” within Florida is subject to jurisdiction for any claim, even one completely unrelated to their Florida activities. The bar is higher than for specific jurisdiction. A single Florida customer is unlikely to qualify. A regional office, dozens of Florida clients, and employees regularly working in the state likely does.3The Florida Legislature. Florida Statutes 48.193 – Acts Subjecting Person to Jurisdiction of Courts of State
Nonresident Drivers
Section 48.171 creates a separate hook. Any nonresident who drives on Florida roads, or lets someone else drive their vehicle here, automatically appoints the Secretary of State as their agent for service of process if an accident happens. The same rule reaches former Florida residents who move away or hide their whereabouts.4FindLaw. Florida Statutes 48.171 – Service on Nonresident Motor Vehicle Owners A Georgia tourist involved in a crash on I-95 can be sued in Florida without the plaintiff traveling to Georgia to serve them.
How Service of Process Must Be Delivered
Jurisdiction is meaningless if the defendant never learns of the lawsuit. Service of process is the formal notice mechanism, and Florida law is exacting about how it must happen.
Personal and Substitute Service
The default is personal service: a process server or sheriff physically delivers the summons and complaint to the person being sued. As an alternative, the papers can be left at the defendant’s usual home with any resident at least 15 years old, provided that person is told what the documents are.5Florida Senate. Florida Statutes 48.031 – Service of Process Generally
Substitute service covers harder situations. A sole proprietor can be served at the business by serving whoever is in charge, but only after two failed personal-service attempts on the owner. If the only address on record is a private mailbox, virtual office, or executive suite, the process server can leave the documents with the person managing that location.5Florida Senate. Florida Statutes 48.031 – Service of Process Generally
Service Through the Secretary of State
For nonresidents subject to Florida jurisdiction, Section 48.161 allows service through the Secretary of State’s office. The plaintiff sends a copy of the process to the Secretary of State addressed to the defendant “in care of” that office, and also sends a copy directly to the defendant’s last known physical address by certified mail or commercial delivery. If the parties have recently communicated electronically, a copy must also be sent electronically. The serving party then files an affidavit within 40 days showing due diligence in locating and notifying the defendant.6The Florida Legislature. Florida Statutes 48.161 – Method of Substituted Service on Certain Parties in Care of the Secretary of State
Who Is Allowed to Serve Papers
Not just anyone. The default rule is that the sheriff in the county where the defendant is located handles service. For civil matters that do not require enforcement, a special process server appointed by the sheriff or a certified process server under Section 48.27 can also serve. The server must be disinterested in the case. Falsifying a return of service is a third-degree felony and permanently bars the person from serving process in Florida.7FindLaw. Florida Statutes 48.021 – Process; By Whom Served
The sheriff’s statutory fee is $40 per summons or writ.8Florida Senate. Florida Statutes 30.231 – Service of Process Fees Private process servers typically charge between $50 and $150 for standard service, with rush or hard-to-locate jobs costing more.
When Traditional Service Fails
Service by publication is a last resort, not a shortcut. Governed by Chapter 49 rather than Chapter 48, it involves publishing a notice in a newspaper in the area where the lawsuit is pending. Courts limit it to specific case types: actions involving Florida real or personal property, divorce, adoption, probate and guardianship matters, paternity proceedings, and cases where a writ of attachment or garnishment has already been executed, among others.9The Florida Legislature. Florida Statutes 49.011 – Service of Process by Publication; Cases in Which Allowed
Before authorizing publication, the court requires proof of a diligent search. One phone call and one address check will not clear the bar. Publication is slow, expensive, and gives the defendant weaker actual notice, which makes any resulting judgment easier to challenge later.
Florida courts can also authorize service through email or social media, but only after all traditional methods have been exhausted and the court specifically approves the alternative. A process server cannot choose this on their own. The party seeking electronic service must show diligent failed attempts at personal delivery, certified mail, and substitute service. If approved, service must go through private messages rather than public posts, and the serving party needs to verify the account actually belongs to the defendant.
The 120-Day Deadline
Florida gives plaintiffs 120 days from filing the initial complaint to complete service. If that window closes without service, the court can dismiss the case without prejudice or drop the unserved defendant. A showing of good cause or excusable neglect may buy an extension, but forgetting or blaming a busy process server rarely qualifies. When a plaintiff amends the complaint to add new defendants, a fresh 120-day clock starts from the date the court grants leave to amend.
The deadline can be a case-killer. A plaintiff who files one day before the statute of limitations expires and then fails to serve within 120 days may be unable to refile because the limitations period has now run.
Challenging Jurisdiction or Defective Service
A defendant who believes the court lacks personal jurisdiction, or that service was defective, must raise it early. Under Florida’s rules of civil procedure, insufficient process and insufficient service of process are affirmative defenses that must appear in the initial responsive pleading or in a motion to dismiss filed before answering. Wait too long and the defense is waived; the court treats the defendant as having consented to jurisdiction.
For nonresidents, the Venetian Salami framework gives two independent grounds to challenge. A defendant can argue the allegations do not fit any category in Section 48.193(1) and do not meet the “substantial and not isolated activity” standard in Section 48.193(2). Separately, even if the statute technically applies, the defendant can argue that exercising jurisdiction violates constitutional due process because their Florida contacts are too thin.10Supreme Court of Florida. Venetian Salami Co. v. Parthenais
What Defective Service Costs
If service was not properly completed, the court never acquires jurisdiction over the defendant. Any judgment entered without valid service is vulnerable to being set aside, regardless of dollar amount or elapsed time. Default judgments are especially common targets. A defendant who was never actually served can move to vacate, and courts are generally receptive when the defect is clear.
One recurring problem: substitute service at an old address. Leaving papers at a former residence does not count as service at the defendant’s “usual place of abode,” even if the defendant lived there recently. The address must be current at the time of service. Confirming the defendant’s current address before attempting service is a small step that prevents an expensive fight later.
