Quick answer, as of 2026-11-02
Service of process is the formal delivery of a summons and complaint, and for an LLC it usually goes to the registered agent on the state's record. In federal court the general deadline to respond is 21 days after service. In Florida state court it is generally 20 days. If the company does not respond, a court can enter a default judgment.

Picture the quiet version of this. A process server walks into the office of your registered agent and hands over a sealed set of court papers addressed to your LLC. If that agent is a relative who moved last spring, or a service you stopped paying, the envelope lands on a desk you never visit. Your company has a few weeks to answer. Nobody tells you the clock started.
Most owners picture a lawsuit arriving with a knock on their own door. For an LLC it usually arrives somewhere else, and that gap between where papers go and where you actually look is what this guide is about. It covers what service means, why the rules exist, the deadlines, how a missed notice turns into a judgment, and what to do the day papers show up.
What Service of Process Means
Service of process is the formal way a plaintiff tells a defendant it has been sued. The plaintiff has the summons and complaint delivered in a manner the court rules allow, and the delivery is what officially starts the defendant's response deadline. A text, an email or a phone call from the other side usually does not count.
A company can't answer its own door, so the law names someone for it. For an LLC that person is generally the registered agent: the individual or business the state lists as the place to send legal papers. In Florida, for example, s. 48.062 says a limited liability company may be served by service on its registered agent.
Delivery to the agent counts as delivery to you, whether or not the agent ever passes the papers along. That is the part owners miss. The law treats your company as notified the moment the right person receives the envelope.
Why the Agent Needs a Street Address
Every state that forms LLCs asks for a registered agent, and for the same reason: a plaintiff needs one reliable place to deliver papers. If a company could dodge a lawsuit by having no address, courts would be useless against it. So the state record has to show a named agent and a physical street address in the state, not a P.O. box.
Some states go further and say when someone must be there. Since October 1, 2025, Florida requires the agent to keep the registered office open from at least 10 a.m. to noon and 2 p.m. to 4 p.m. on weekdays, with one or more individuals present who can accept papers (s. 48.091(3), as amended by ch. 2025-13). The point is that a process server can show up on an ordinary weekday and find a real person to hand the papers to.
If the agent can't be found, the lawsuit doesn't stop. Under Florida's s. 48.062, when a company has no registered agent, or the agent can't be served after one good faith attempt, the plaintiff may serve a manager, a member, or a person listed on the company's latest annual report. If that also fails after due diligence, the statute allows service on the Secretary of State. In other words, a missing agent gives the plaintiff more routes to serve you, and most of them are routes you are not watching. Other states have their own versions of this fallback, so check yours.
How Long You Have to Respond
The deadline runs from the date of service, not from the day you open the envelope. Courts set their own windows, and the summons itself normally states the one that applies. These are the general rules for two common courts.
| Court | General time to respond | Official source |
|---|---|---|
| Federal court | 21 days after being served with the summons and complaint. If the defendant timely waived service, 60 days after the waiver request was sent. | Fed. R. Civ. P. 12(a)(1)(A) |
| Florida state court | 20 days after service of original process and the initial pleading, unless a Florida statute sets a different time. | Fla. R. Civ. P. 1.140(a)(1) (Florida Bar PDF) |
Those windows are short on purpose. Twenty days is under three weeks, and it includes weekends. An owner who finds the papers in a drawer a month later may already be past the deadline. Other states use other numbers, and some claim types have different rules, so treat the figures above as examples and read the summons.
From Missed Notice to Default Judgment
A default is what the court system does when a defendant doesn't show up. In federal court, when a party seeking relief shows that the defendant has not pleaded or otherwise defended, Rule 55(a) says the clerk must enter the defendant's default. Under Rule 55(b), the clerk can then enter judgment for a fixed sum on request, and in other cases the court does. State courts have comparable steps with their own names and timing.
What makes this dangerous is that none of it needs your cooperation. The plaintiff doesn't have to prove its case against a defense you never filed. It has to show it served you properly and that you didn't respond.
One way it plays out (hypothetical). Marcus runs a roofing LLC in Tampa. When he formed it, he listed his cousin as registered agent at her apartment. She moved to Ohio and never told him. A customer sues over a disputed invoice, and a process server tries the apartment on the state's record. The papers end up with the person who now lives there, or with the Secretary of State, and not with Marcus. The response deadline passes. The first he hears of it is a letter saying a default judgment has been entered, and then a call from his bank. Every step was routine for the court. The only thing missing was a person at his company who knew in time.
The point of the story isn't that the customer was right. Maybe the invoice dispute was weak and Marcus would have won. A default judgment means the court never heard his side. Once a judgment exists, the plaintiff can generally use it to try to collect from the company; what collection looks like depends on the state and the court. Courts can sometimes set a default aside, but that is a motion with its own standards and deadlines, and only an attorney in that court can tell you whether it applies to your case.
Separately, an LLC that has no agent on file can be administratively dissolved, which is its own problem. Our guide on changing your registered agent without a gap covers the gap risk, and reinstating an LLC covers what comes after a dissolution.
What to Do the Day Papers Arrive
Treat the papers as urgent even if they look wrong, and work through the same short list each time.
Call an attorney that day
Do not wait to see whether the other side calls. A licensed attorney in the court's state can tell you what the deadline is, what a response looks like, and whether more time is available. If you have never hired one, your state bar's referral service is a place to start.
Find the date and write it down
Note the day and way the papers were delivered, who received them, and the deadline stated on the summons. Keep the envelope, every page and any cover letter. Put the deadline on a calendar with a reminder a week ahead.
Do not ignore it, and do not assume it is a mistake
Plenty of papers look like a mistake: the wrong name, a claim you have never heard of. A court can still treat them as valid service. If you think the papers are fake, check with the court clerk or an attorney rather than the sender. Our Is This Notice Real? tool helps you sort official notices from scams, but it does not replace a lawyer on a summons.
Sort the rest of your legal mail
A summons is one kind of notice among many. RA Notice Triage sorts registered agent mail by urgency, so a court paper isn't buried under junk. If the LLC operates in more than one state, the Multi-State RA Consolidator shows where each agent stands.
The deadline does not pause while you look for a lawyer. If you are close to it, tell the attorney the date in your first sentence.

Common Questions
What does it mean when an LLC is served?
Being served means a plaintiff has formally delivered a summons and a copy of the complaint to the LLC in the way the law allows, usually by handing them to its registered agent. Service is what starts the response clock. It does not mean you lost. The case has begun, and a deadline is running.
How long does an LLC have to respond to a lawsuit?
It depends on the court. In federal court the general answer deadline is 21 days after service (Federal Rule of Civil Procedure 12(a)(1)(A)(i)). In Florida state court it is generally 20 days after service (Florida Rule of Civil Procedure 1.140(a)(1)), unless a statute sets a different time. Other states set their own windows, and a summons usually states the deadline, so read it the day it arrives.
What happens if my LLC does not respond to a lawsuit?
In federal court, when a defendant has not pleaded or otherwise defended, the clerk must enter its default, and the court can then enter a default judgment (Rule 55). State courts have their own versions of this process. A judgment can then be used to try to collect from the company, so ignoring the papers is the costly choice.
Who can accept service of process for an LLC?
Usually the LLC's registered agent. Florida's statute also lets a plaintiff serve a manager, a member, or a person listed on the latest annual report if the agent has ceased to exist or cannot be served after one good faith attempt, and then the Secretary of State if that still fails (s. 48.062). Rules vary by state, so ask an attorney about yours.
Why does a registered agent need a physical address and business hours?
So a process server always has a real person and a real street address to hand papers to. Florida's statute requires the registered office to be open 10 a.m. to noon and 2 p.m. to 4 p.m. on weekdays with someone there to accept service (s. 48.091(3)). A P.O. box or an empty office defeats the purpose.
What should I do the day my business is served with papers?
Write down the date and how you received them, keep every page, find the response deadline on the summons, and call a licensed attorney that day. Do not ignore the papers and do not assume it is a mistake. If you are unsure the papers are real, our guide to spotting fake notices covers the checks, but verify with the court or an attorney before you decide.
How does a registered agent service prevent a missed notice?
A commercial agent keeps a staffed street address, receives the papers on the day they are delivered, and sends you a scan and an alert so you can act inside the deadline. Registered agent service through our partner Registered Agents Inc is $74.25 a year, the same price at renewal. It does not replace an attorney. It makes sure you know in time to call one.
A lawsuit gives you 20 or 21 days, and nobody warns you before they start. Make sure the address the state has on file is one where somebody reads the mail the day it arrives.
