THE MAYN FIELD NOTES · PARALEGAL BRIEF
Practical brief for Florida litigation paralegals and the attorneys they support.
The return of non-service lands on your desk and the deposition is in three weeks. An unserved subpoena in Florida is a common problem with a predictable fix: figure out why service failed, develop a better address, and document the effort in case you need the court’s help. This checklist walks through the next steps in order.
Witness keeps dodging service? We can help locate them.
Call (321) 340-3280 to talk it through with a licensed investigator. We discuss rates by phone and can usually start quickly. Prefer to write? Use our case request form.
Step 1: Read the return closely
The process server’s affidavit or notes usually tell you more than “not found.” Look for:
- Did a current occupant say the witness moved, and when?
- Was the address vacant, for sale or a business?
- Did someone say the witness lives there but is “never home”?
- Were there vehicles, names on mail or a gate code issue?
- How many attempts, on which days and at what times?
Each answer points to a different next step. “Moved six months ago” means a new locate. “Lives here, never home” means better timing, a workplace attempt or a conversation with counsel about substituted service options under section 48.031, Florida Statutes.
Step 2: Confirm you have the right person
Before spending more on service, confirm the identifiers. Common names, a missing middle name or a wrong date of birth send process servers to the wrong door. Pull together everything in the file: full name, aliases, date of birth or age, last known addresses, phone numbers, email addresses, employer, vehicles and relatives.
Step 3: Send the investigator a clean package
A focused package gets a faster, better locate. Send:
- The case caption, the witness’s role and the subpoena date or deadline.
- All identifiers from Step 2, marked as confirmed or uncertain.
- The process server’s returns and notes.
- Any prior statements, incident reports or records that mention the witness.
- Counsel’s instructions on contact: locate only, or locate and approach.

Step 4: Locate and verify
A licensed investigator develops a current address from lawfully licensed databases, public records, employment and licensing information, public social media and, where needed, a field check to confirm the witness actually lives there. A database hit alone is a lead. A verified address is what your process server needs. See our witness locates service and our guide to locating a witness or defendant in Florida.
Step 5: Coordinate the next service attempt
- Share the verified address and the best times observed with the process server.
- Consider a workplace attempt if counsel approves.
- If the witness is out of state, flag it early. Counsel will need to consider the procedure for out-of-state subpoenas, which takes time.
Step 6: Protect the date
If service still is not happening, tell the attorney early. Counsel may want to reschedule, seek relief from the court, or adjust the witness plan. A documented record of each attempt and each locate step makes those conversations easier and supports any motion. For defendants, where constructive service is on the table, see our guide to diligent search for service by publication in Florida.

FAQ
Can the investigator serve the subpoena?
Service in Florida is handled by people authorized to serve process. We locate and verify, then coordinate with your process server.
How fast can a witness be located?
It depends on the identifiers and how far the witness has moved. Call with the deadline and we will tell you what is realistic.
Will you contact the witness?
Only if counsel asks us to. Many firms want a locate only. When we do make contact, we are truthful about who we are and do not discuss testimony unless counsel directs it.
