Legal and Ethical Standards, Contracts, and Civil Rights
Core Duties
Investigative work sits at the intersection of contract, tort, and constitutional law. A candidate must understand the investigator-client relationship as a contract: scope of engagement, fees, confidentiality, conflicts of interest, and termination. Know the ethical duties of honesty, competence, avoiding conflicts, safeguarding client information, and not misrepresenting identity in ways that cross legal lines. Distinguish lawful pretext from impersonating law enforcement, which is prohibited.
Civil Rights and Privacy
Understand the constitutional limits on state action and how they apply when an investigator works for a government client versus a private client. Private investigators are generally not state actors, but they can become entangled with police conduct. Know privacy torts (intrusion upon seclusion, public disclosure of private facts), wiretap and eavesdropping limits, trespass, and defamation risk in reports. Traps: assuming a private investigator may wiretap with one-party consent beyond what law allows, or that consent to search given by a third party is always valid.
Traps and Rule of Thumb
Questions test whether you can separate civil liability from criminal liability and whether the investigator's conduct is judged by contract terms or by statutory duties. Rule of thumb: if the client asks for something that would be illegal if a police officer did it without a warrant, assume it is illegal for you too unless a clear private-party exception applies.
Worked Example
A client asks the investigator to place a GPS tracker on a spouse's car. The investigator must confirm ownership, applicable statute, and consent before acting; ownership by the client does not automatically authorize tracking a vehicle the subject also uses. Document the legal basis in the file.
