Diligent Search for Service by Publication in Florida: What Courts Expect

Practical brief for Florida litigation and family law paralegals and attorneys.

When personal service fails and publication is the only way forward, the quality of your diligent search decides whether the judgment holds. A Florida diligent search is not a box to check. It is the factual record the court relies on to find that you genuinely tried to locate the person before giving notice in a newspaper instead of at their door.

This guide covers what Chapter 49 requires, what Florida courts look for when constructive service is challenged, and how a licensed investigator documents a search so the sworn statement is specific, accurate and defensible.

When service by publication is available in Florida

Constructive service is the exception, not the rule. Section 49.011, Florida Statutes, lists the kinds of actions in which service by publication may be made. They include, among others, actions to enforce a lien or claim to property within the court’s jurisdiction, quiet title, partition, dissolution or annulment of marriage, actions in which garnishment, replevin or attachment has been issued and executed, revival of a judgment, adoption, and certain probate, guardianship and paternity matters.

Two practical points follow. First, publication is tied to the type of action, so counsel has to confirm the case fits the statute before anyone spends money on a newspaper notice. Second, publication generally supports relief tied to property, status or the res before the court. Whether it supports a particular form of relief, such as a personal money judgment, is a legal question for counsel, and it is one more reason to push hard for personal service first.

What the sworn statement must show

For a natural person, section 49.041 requires a sworn statement by the plaintiff, the plaintiff’s agent or attorney showing, among other things, that diligent search and inquiry have been made to discover the person’s name and residence, set out as particularly as is known to the affiant, and whether the person is over or under 18, if known. The statement must also address residence, for example that it is unknown, or that it is outside Florida, or that the person has been absent from the state or is concealing themselves so that personal service cannot be made.

The family law version makes the expectation concrete. The instructions to Florida Supreme Court Approved Family Law Form 12.913(b), Affidavit of Diligent Search and Inquiry, say the court must believe you made a very serious effort to find the other party and that you followed up on information you received. The form includes a checklist of places to look. Not every source applies in every case, but that checklist is a good signal of the effort courts expect.

Why thin searches get judgments vacated

Constructive service is often challenged after the fact, usually when the defendant surfaces and moves to set aside a default. At that point, the trial court has the duty to determine not only whether the affidavit of diligent search is legally sufficient but also whether the plaintiff actually conducted an adequate search, as the Third District explained in Giron v. Ugly Mortgage, Inc., 935 So. 2d 580 (Fla. 3d DCA 2006).

The Fourth District applied that principle in Howard v. Gualt, No. 4D18-1451 (Fla. 4th DCA Oct. 31, 2018), reversing an order that refused to vacate a default judgment entered after publication, where the guarantor argued the plaintiff’s search leaned on business-entity records and a few attempts at known addresses. The lesson for practitioners is simple: a search that would have found the person with a bit more work is a weak foundation for a judgment.

A conclusory affidavit that says “diligent search was made” without describing what was searched invites exactly that challenge. A documented search protects the judgment and the client who paid for it.

What a defensible Florida diligent search looks like

There is no single statutory list for every case type, so we build the search around the person and the facts. A typical search for a natural person covers:

• Identity resolution first. Full name, known aliases, date of birth or approximate age, and other identifiers so we are tracking the right person and not a namesake.
• Address history. Lawfully licensed investigative databases and credit-header-based address histories, used under a permissible purpose, with every address dated and sourced.
• Public records. County official records and property appraiser data, clerk of court dockets in Florida and likely other states, traffic and criminal case records, Sunbiz entity filings, professional licenses, and vessel or aircraft registrations where relevant.
• Custody and incarceration checks. County jail rosters, the Florida Department of Corrections and the federal Bureau of Prisons locator.
• Death records. Obituary and death index searches, so the case is not chasing a person who has died.
• Military status. A Servicemembers Civil Relief Act status check, which counsel will also need before a default.
• Open-source review. Public social media, employer and business websites, and news mentions for current city, workplace or relatives. We view only what is public. No friend requests, no fake profiles.
• Relatives and associates. Identifying people likely to know the current address. Any contact is discreet and truthful about who we represent where required, and we follow counsel’s direction on whether to make contact at all.
• Field verification. Where leads point to a Florida address, a site visit to confirm occupancy, vehicles, mail or neighbors’ information, documented with dates and times.

Every step is logged. If a lead dies, the report says how and why. That log becomes the factual basis counsel uses to prepare the sworn statement, or it becomes the address the process server needs. In many of our assignments the second outcome is the goal: a located defendant is always better than a published notice.

Common mistakes we see

• Relying on one database. Commercial address data is often stale. One search result is a lead, not a conclusion.
• Not following up. The family law form instructions specifically mention following up on information received. A relative’s tip that was never checked looks bad later.
• Ignoring other states. If the person is likely out of state, the search should say where and what was checked there.
• Stale searches. A search run months before the affidavit is signed may not reflect current facts. Refresh before filing.
• Vague affidavits. Summarize what was searched, when, and the results, consistent with the investigator’s report.

How a licensed investigator supports the process

MAYN Investigations is a Florida private investigation agency licensed under Chapter 493 (agency license A3400126). For diligent search assignments we work at counsel’s direction and deliver a dated, sourced report: who we searched for, which identifiers we used, every source checked, every address developed and how it was ruled in or out, and any field verification. If we find a current address, we say so and, where requested, coordinate with your process server. Learn more about our skip tracing, witness locates and process service support work, or read our guide to locating a witness or defendant in Florida.

We handle these searches statewide, including for counsel in Orlando, Tampa, Jacksonville and Volusia County.

FAQ: diligent search and service by publication in Florida

Who signs the sworn statement for publication?

Under section 49.041, the sworn statement is made by the plaintiff, the plaintiff’s agent or attorney. The investigator’s report gives the affiant the specific facts to state accurately. Counsel decides who signs and what it says.

Can a private investigator testify about the search?

Yes. If constructive service is challenged, the investigator who did the work can explain the sources, dates and results. That is one reason we document every step.

How long does a diligent search take?

It depends on the identifiers you have, the number of states involved and whether field verification is needed. Call with your deadline and we will tell you what is realistic.

What should a paralegal send the investigator?

The full legal name and aliases, date of birth or approximate age, last known addresses, the process server’s affidavits of non-service, known employers, relatives, vehicles, phone numbers and email addresses, and the case caption and deadline.

Is a diligent search the same as skip tracing?

They overlap. Skip tracing aims to find the person. A diligent search also documents the effort for the court. We do both in the same assignment, so if the person is found you serve them, and if not you have a record.

Do you serve the papers too?

We coordinate with your process server and support service with location work and field verification. Ask us about the right setup for your county.
