Questions to ask
Questions to ask before hiring a private investigator
Check the license, the scope of work, the written terms, and what the investigator can legally deliver.
Is the InmateLink private investigator directory live yet?
No. This marketing page is live, but the InmateLink private investigator directory is still being prepared and does not contain investigator listings yet. Nothing on this page represents a ranked, approved, or recommended list. A future profile would still need review and would not guarantee publication, placement, calls, or results.
What kinds of work do private investigators perform?
Services vary by investigator and may include legal-investigation support, locating people or property, interviews, records research, background work, lawful surveillance, fraud investigation, or evidence gathering. Not every investigator performs every service, and some work may require a specific license or legal authority. Confirm the exact service, limits, and intended deliverable before hiring.
How can I check whether a private investigator is licensed?
Check the official state licensing or regulatory authority for the investigator and, when applicable, the investigative business. Search the current status, business name, license number, and any public disciplinary information the authority provides. Requirements and job titles vary by state, so a license in one place may not authorize work somewhere else.
What should I ask a private investigator before hiring them?
Ask about current licensing, experience with the type of work, legal and geographic limits, proposed scope, communication, expected deliverables, subcontractors, confidentiality, fees, and expenses. Request written terms that explain what work is authorized and when updates will be provided. A clear scope helps both sides understand the assignment without promising a particular result.
How do private investigators normally charge for their work?
Arrangements vary and may include hourly work, retainers, flat fees, travel, mileage, database expenses, court time, or other costs. Ask for a written scope, billing intervals, expense rules, and what happens when the budget or retainer is reached. Confirm whether unused funds may be returned. InmateLink does not quote typical investigator prices.
Can a private investigator work in another state?
It depends. Licensing, business registration, reciprocity, and permitted activities vary by jurisdiction, and crossing a state line does not automatically authorize the work. Verify through the appropriate state authority that the investigator and business may legally perform the specific assignment in every relevant location. Ask how any local partner or subcontractor will be selected and identified.
What information should I provide to a private investigator?
Provide accurate, lawfully obtained background, the legitimate purpose and scope of the request, known dates and locations, relevant public documents, and useful contact details. Explain what you need the investigator to deliver. Do not request hacking, impersonation, harassment, unlawful access to records, prohibited surveillance, or any act you would not be legally permitted to perform.
Can a private investigator guarantee a result?
No. An investigator cannot guarantee that a person, witness, record, asset, or particular evidence will be found. Access, time, law, available records, cooperation, and the facts themselves can limit the result. Ask what work will be attempted, what documentation will be delivered, how progress is reported, and how the investigator explains an unsuccessful or incomplete search.
InmateLink does not recommend an investigator or promise an investigative result.
