PA Private Investigator cheat sheet

The Private Detective Act of 1953 is codified at 22 P.S. §§ 11–30; it regulates private detective and investigative businesses operating in Pennsylvania.

The Act requires licensure of the business and registration of employees; unlicensed operation is a summary offense for a first violation and a misdemeanor for subsequent violations.

Licensed entities must maintain a confidential records system; client information is not a public record and may be disclosed only as authorized by law or client consent.

The Pennsylvania State Police (PSP) administers licensing and registration under the Act, including application review, background checks, and issuance of licenses and identification cards.

The Act does not authorize private detectives to exercise police powers; licensees have the same arrest authority as private citizens under 18 Pa.C.S. § 508 (citizen's arrest in limited circumstances).

A private detective license is required for any person who, for hire, investigates crimes, the identity or conduct of individuals, or the location of lost or stolen property.

Exemptions from licensure include: attorneys acting in the course of professional duties; insurance company adjusters investigating claims; and employees of licensed entities acting within scope of employment.

The Act imposes a duty on licensees to cooperate with law enforcement and to report certain information, but does not create a general obligation to report all client matters.

Applicants for a private detective license must be at least 21 years old, of good moral character, and have at least three years of experience or equivalent training as determined by the PSP.

A surety bond in an amount set by the PSP (currently $10,000) must be filed with the license application and maintained during the license period.

Each employee who performs investigative work must be registered with the PSP; registration requires fingerprints, a background check, and a fee.

Licensees must notify the PSP within 15 days of any change in business address, name, or ownership, and of the termination of any registered employee.

A license is valid for one year and must be renewed; late renewal may require payment of a penalty and may result in a lapsed license.

Applicants must disclose any criminal convictions; certain felonies and misdemeanors may disqualify an applicant or employee from licensure or registration.

Registered employees must carry their PSP-issued identification card while on duty and display it upon request to law enforcement or clients.

The Act prohibits licensees from employing persons who are not registered to perform investigative services; doing so may result in suspension or revocation of the license.

Private detectives may conduct investigations, interviews, and surveillance, but have no authority to detain, search, or arrest persons except as permitted by citizen's arrest law (18 Pa.C.S. § 508).

Prohibited conduct includes impersonating a law enforcement officer (18 Pa.C.S. § 4912), falsely representing oneself as a police officer, and wearing or displaying police insignia.

Licensees may not use wiretaps, electronic eavesdropping, or interception of communications unless authorized under the Pennsylvania Wiretapping and Electronic Surveillance Control Act (18 Pa.C.S. §§ 5701–5782).

It is unlawful to engage in stalking (18 Pa.C.S. § 2709.1) or harassment (18 Pa.C.S. § 2709) under the guise of investigation; surveillance must not place subjects in reasonable fear of bodily injury.

Private detectives may not access criminal history record information (CHRI) from the PSP or FBI without authorization; unauthorized access violates the Criminal History Record Information Act (18 Pa.C.S. § 9101 et seq.).

Licensees are prohibited from using pretexting to obtain financial records or telephone records (15 U.S.C. § 6821; 18 U.S.C. § 1039) and from unauthorized access to computer systems (18 Pa.C.S. § 7611).

The Act prohibits splitting fees with unlicensed persons or paying commissions to non-licensees for client referrals; such arrangements may constitute unlicensed activity.

Licensees must not engage in the practice of law, give legal advice, or represent clients in legal proceedings; they may provide factual reports and testify as witnesses.

Pennsylvania crimes are classified as summary offenses, misdemeanors (1st, 2nd, 3rd degree), and felonies (1st, 2nd, 3rd degree); the classification determines the maximum penalty and the court of jurisdiction.

The statute of limitations for most felonies is five years (42 Pa.C.S. § 5552); for misdemeanors it is two years; no limitation applies to murder or certain specified offenses.

A citizen's arrest is permitted when a felony or breach of the peace is committed in the presence of the arresting person, or when the person has reasonable grounds to believe a felony was committed and the suspect is fleeing (18 Pa.C.S. § 508).

The exclusionary rule applies to evidence obtained through unlawful searches or seizures by government actors; private detectives are not generally subject to the exclusionary rule unless acting as agents of law enforcement.

Private detectives must be aware of the Miranda rule: it applies only to custodial interrogation by law enforcement; private detectives are not required to give Miranda warnings unless acting in concert with police.

The corpus delicti rule requires that a crime be proven by evidence independent of a defendant's confession before the confession can be admitted.

Chain of custody is essential for physical evidence; any break in the chain may affect admissibility and weight, and must be documented.

Privileged communications (attorney-client, physician-patient, clergy-penitent) may not be disclosed by private detectives who learn of them; unauthorized disclosure may violate statutory privileges.

Chain of custody must record each person who handled the evidence, the date and time of transfer, and the purpose of each transfer; gaps or undocumented transfers can lead to exclusion or reduced weight.

Physical evidence should be collected using gloves and clean tools, placed in appropriate containers (paper for biological evidence to prevent mold, plastic for non-biological), and sealed with tamper-evident tape.

Each evidence container must be labeled with a unique case number, item number, description, date, time, location, and collector's name; the label should be initialed across the seal.

Photographs of evidence should include a scale and be taken before any movement or alteration; digital photographs should preserve metadata and be hashed for integrity.

Documentation should be contemporaneous; notes must be dated, timed, and signed, and any corrections should be made with a single line-through and initials, not erasure.

A written evidence log should be maintained separately from the evidence itself, recording every transfer, and should be stored securely with the evidence or in a secure case file.

For digital evidence, use write-blocking tools to preserve original media, document hash values (e.g., SHA-256) before and after analysis, and maintain a duplicate working copy.

At the conclusion of a case, evidence should be returned to the client or destroyed according to a written policy, with a receipt obtained and documented in the file.

Surveillance must be conducted from public vantage points or with the consent of the property owner; trespassing on private property to observe is prohibited (18 Pa.C.S. § 3503).

Mobile surveillance should use a minimum of two vehicles and maintain a safe following distance; the lead vehicle maintains visual contact while the second provides backup and communicates location.

Foot surveillance requires the investigator to blend with the environment, avoid direct eye contact, and use reflective surfaces or shop windows to monitor the subject without being detected.

Observation notes should record time, location, subject description, actions observed, and weather/lighting conditions; these details support later testimony and reports.

Pretext interviews are lawful if the investigator does not impersonate law enforcement, does not obtain information under false pretenses from financial institutions, and does not commit fraud.

Trash pulls may be lawful if the trash is placed at the curb for collection and the investigator does not trespass; however, any evidence obtained must be documented and handled properly.

GPS tracking of a vehicle may require a warrant if it involves trespass or continuous monitoring; under Pennsylvania law, installation of a GPS device on a vehicle without consent may constitute a violation of the Wiretap Act or trespass.

Undercover investigations require careful planning, documentation, and avoidance of entrapment; the investigator must not induce a person to commit a crime they were not predisposed to commit.

The Pennsylvania Wiretapping and Electronic Surveillance Control Act (18 Pa.C.S. §§ 5701–5782) prohibits interception of oral, wire, or electronic communications without the consent of all parties.

Pennsylvania is a two-party consent state for oral communications; recording a conversation without the consent of all participants is a felony unless an exception applies (e.g., law enforcement with court order).

Exceptions to the two-party consent rule include: recording by a party to the communication who is a victim of a crime of violence, or recording by law enforcement under a court order.

Installation of a tracking device on a vehicle without consent may violate the Wiretap Act (18 Pa.C.S. § 5703) and trespass laws; a court order is advisable.

The Stored Communications Act (18 U.S.C. § 2701) prohibits unauthorized access to stored electronic communications; private detectives may not access email or social media accounts without lawful authorization.

The Computer Fraud and Abuse Act (18 U.S.C. § 1030) and Pennsylvania computer trespass statute (18 Pa.C.S. § 7611) prohibit unauthorized access to computers and networks.

The Fair Credit Reporting Act (15 U.S.C. § 1681) regulates consumer reports; private detectives conducting background checks for employment purposes may be considered consumer reporting agencies and must comply with FCRA requirements.

The Gramm-Leach-Bliley Act (15 U.S.C. § 6801 et seq.) restricts obtaining financial information under false pretenses; pretexting for financial records is prohibited.

Private detectives must avoid conflicts of interest; a conflict exists when the investigator's personal interests or prior relationships could impair objectivity or loyalty to the client.

Confidentiality is a core ethical duty; client information must not be disclosed without consent or legal compulsion, and must be protected from unauthorized access.

Investigators must not accept engagements that require illegal or unethical conduct, such as obtaining information through deception that violates law or professional standards.

Fees must be disclosed in writing before work begins; contingent fees based on the outcome of a criminal case may be unethical and potentially illegal.

Investigators should not communicate with a represented party in a legal matter without the consent of that party's attorney, as this may violate rules of professional conduct.

Testimony must be truthful; perjury (18 Pa.C.S. § 4902) and false swearing (18 Pa.C.S. § 4903) are crimes, and ethical standards require candor to the court.

Investigators should maintain professional boundaries and avoid personal relationships with clients or subjects that could compromise objectivity or create undue influence.

Continuing education and adherence to professional association codes (e.g., ASIS, NCISS) are recommended but not statutory requirements; however, they inform ethical practice.

Reports should be written in clear, factual, and objective language; include case number, date, time, location, persons involved, actions taken, and observations; avoid opinions unless qualified as expert.

Testimony should be prepared by reviewing notes and reports; the investigator should testify only to facts personally observed or reliably reported, and should not speculate.

The investigator should use notes to refresh memory; opposing counsel may be entitled to inspect the notes used, so ensure notes are preserved and consistent with the report.

Client communication should be timely and documented; keep clients informed of significant developments, and obtain written authorization for any change in scope or fees.

Reports may be discoverable in litigation; write them with the assumption they will be read by opposing counsel, and avoid unnecessary personal comments or conclusory statements.

When testifying, address the court as 'Your Honor,' avoid jargon, speak clearly, and answer only the question asked; do not volunteer information.

If subpoenaed, the investigator must appear unless excused by the court; failure to appear may result in contempt.

Client files should be retained for a period consistent with statute of limitations and professional standards (typically at least 5 years); destruction should be documented.
