Describe what you need to decide or prove, the facts already known, the jurisdiction and any deadline. Asking only for a tactic—such as “follow this person”—can lead to unnecessary cost without answering the underlying question.
Verify licensing where required, relevant experience, conflicts, communication practices, evidence handling and how findings will be reported. Be cautious of guaranteed results, claims of unrestricted database access or promises to hack accounts.
A practical hiring framework
Choose the investigator by scope, method and accountability
Hiring a private investigator is not simply a search for someone willing to perform surveillance or run a database search. The right investigator should understand the decision you face, identify which facts could change that decision and explain a lawful, proportionate way to obtain them.
A professional consultation should define the question, lawful methods, fees, limits and expected deliverables before work begins.
Credentials matter, but a license alone does not prove that an investigator has the experience, communication skills or evidence practices your matter requires. Evaluate the business, the person responsible for the work and any specialists or subcontractors who may participate.
For California matters, consumers can verify a private-investigator license through the Bureau of Security and Investigative Services. California agreements for private-investigator services must be in writing under requirements effective July 1, 2025. Other jurisdictions may use different licensing and contract rules.
Define the result you actually need
Prepare a short account of the known facts, important dates, jurisdiction, deadline and decision the investigation should support. Separate what you personally know from what another person reported and from what you suspect.
A good investigator will refine the question before recommending a method. If the proposed work cannot reasonably change your decision or support counsel’s strategy, it may not justify the expense.
Verify the license and the business identity
Where licensing is required, check the regulator’s official database rather than relying on a website badge or a copy of a license. Confirm the license holder, business name, status and location, and ask who will supervise and perform the work.
License status verified through the responsible government regulator
Legal business name and professional contact information
Identity of the qualified manager or responsible investigator
Use of subcontractors and the jurisdictions in which they will work
Match experience to the specific assignment
Surveillance, fraud analysis, background research, digital forensics, international coordination and expert testimony require different skills. Ask for relevant examples described without disclosing another client’s confidential information.
The investigator should be able to explain the method, common limitations and typical deliverable in plain language. Prior law-enforcement experience or technical credentials may be valuable, but neither automatically establishes fit for your matter.
Ask how the work will remain lawful and defensible
Discuss authority, privacy, recording, access, evidence preservation and jurisdiction before work begins. A responsible investigator will decline methods that involve hacking, pretexting for protected records, trespass, unauthorized tracking or access to private accounts.
Be cautious when someone promises secret access to any database, claims laws do not apply to investigators or guarantees a result before reviewing the facts.
Require a clear written agreement and fee structure
The agreement should identify the client, objective, authorized services, important limits, rates, expenses, retainer terms, communication expectations and the basis for ending or expanding the assignment. Read how unused funds and third-party costs are handled.
Defined scope and the question each task is meant to answer
Hourly, flat or phased fees and any minimum billing periods
Travel, database, records, equipment and subcontractor expenses
Approval requirements for work beyond the initial budget
Expected reporting format, milestones and final deliverables
Evaluate reporting, security and communication
Ask how evidence will be received, preserved, stored and returned; how sensitive communications will be protected; and how observations, source material and inference will be separated in the report. For litigation, discuss coordination with counsel and possible testimony before fieldwork or examination begins.
Compare proposals by usefulness, not just price. A narrow, well-documented phase with a review point may provide more value than a large open-ended assignment. You should understand what happens next if the first phase confirms nothing, identifies a new lead or reaches a legal or practical limit.
A good investigator makes the engagement clearer before it becomes larger
Use the initial consultation to test judgment as much as capability. The investigator should ask focused questions, explain uncertainty, identify lawful limits and provide a written plan you can evaluate before authorizing substantial work.

Questions
Frequently Asked Questions
How do I verify a private investigator in California?
Use the California Bureau of Security and Investigative Services official license-verification system. Confirm the license status, name and business information rather than relying only on a website or document supplied by the investigator.
What should a private investigator agreement include?
The written agreement should clearly identify the parties, objective, authorized scope, rates and expenses, retainer terms, important limits, communication expectations and expected deliverables. Applicable requirements depend on the jurisdiction.
Should I choose the least expensive investigator?
Price matters, but compare the proposed scope, relevant experience, lawful method, supervision, evidence practices and reporting. A cheaper open-ended assignment may cost more than a focused phased plan.
What are warning signs when hiring a private investigator?
Warning signs include guaranteed outcomes, promises to hack accounts, claims of unrestricted protected-record access, refusal to provide a written agreement, unclear fees and pressure to authorize broad work before the objective is defined.
