What to Bring to Your First Call With a Private Investigator

What should you have ready before you call a private investigator?

A clear goal, a short timeline, and the names, dates and documents tied to your question. Investigators can only work from what they are given, so a little preparation at the start helps them scope the job accurately and tells you sooner what is realistic.

Why does preparation matter?

A first call usually covers three things: what you need to know, what is already known, and what can be done lawfully within your timeframe and budget. When the details are organized, that conversation is shorter and the scope is easier to define. When they are scattered, the first hour often goes to sorting facts instead of planning.

What should you write down first?

  • Your goal in one or two sentences. “I need to confirm whether this company is registered and who owns it” is workable. “I need to know everything” is not.

  • A short timeline. Dates, places and events in order, even if some are approximate. Mark which items you know and which you suspect.

  • Your deadline, if any. Some questions are time-sensitive. Say so early.

Which names and identifiers help most?

Full legal names with correct spelling, known aliases, approximate ages, last known addresses, phone numbers, email addresses, usernames, and vehicle or business names. Spelling matters. Common names produce wrong matches in any background investigation, and details like a middle name or a past address help separate one person from another.

Which documents and records should you gather?

Anything you already hold: contracts, invoices, emails, text messages, screenshots, photos, and notes about conversations. Save them as they are. Do not edit, crop or delete originals, and keep the dates and sender information visible. If something lives on a website or social account that could change, capture it now. Our overview of how investigators use social media shows why timing matters.

What should you avoid doing before you call?

  • Confronting the person involved. It can change behavior, move or remove evidence, and close off options.

  • Accessing someone else’s accounts, devices or messages. Even with good intentions, this can create problems of its own.

  • Deleting or “cleaning up” your own records. Keep everything, including items that seem unhelpful.

What should you ask the investigator?

Ask for the license number and look it up yourself with the Florida Department of Agriculture and Consumer Services license search. Then ask what the scope is, what the deliverable looks like, how updates are handled, and how fees work. We list six more questions in how to vet a private investigator before you hire. General pricing information is on our rates page.

Does a prepared first call guarantee an outcome?

No. An investigator cannot promise a result, and a good one will say so. Preparation helps define the question, avoid duplicated effort and set realistic expectations. What can be found still depends on the facts, the records available and the law.

Frequently asked questions

Do I need all of this before I call?
No. Bring what you have. Gaps are normal, and a good first call helps identify what is missing.

Should I send documents before the call?
Ask the investigator how they prefer to receive them. Many will ask for a short summary first.

Is what I tell an investigator confidential?
Ask about confidentiality and how your information is stored before sharing sensitive details.

What if I am not sure what I am trying to learn?
Say that. Describing the situation and what worries you is a reasonable place to start, and an investigator can help turn it into a specific question.
