Alabama One-Party
Licensing & Regulation
Alabama does not require statewide licensure of private investigators. Investigators are governed instead by general business-licensing requirements and by municipal ordinances in larger cities such as Birmingham, Mobile, and Montgomery, which may require a local business permit. Some PIs voluntarily certify through the Alabama Private Investigators Association. Attorneys, journalists, and bail-enforcement agents performing investigative work in the scope of their primary occupation are generally exempt from any local registration. Out-of-state PIs working temporarily in Alabama should still maintain a license in their home state and observe any local business-permit rules.
Physical Surveillance
Surveillance in genuinely public spaces — sidewalks, streets, public parks, the exterior of commercial buildings — is permitted without consent. Investigators may follow a subject and photograph them in public so long as they do not trespass, harass, or place the subject under a reasonable apprehension of harm. The curtilage doctrine protects the area immediately surrounding a home from intrusive observation. GPS tracking of a vehicle owned by the investigator's client (or jointly owned in a marital context) is generally permissible; placing a tracker on a vehicle owned solely by the subject is risky and may amount to civil trespass or stalking.
Audio & Video Recording Consent
Alabama is a one-party-consent state under Code of Alabama §13A-11-30 et seq. (eavesdropping statutes). A PI who is a party to a conversation may record it without the other party's consent. Surreptitious recording of a conversation to which the PI is not a party is illegal. Hidden cameras may be deployed in public or semi-public spaces, but Alabama's "criminal surveillance" statute prohibits recording in places where a person has a reasonable expectation of privacy (bathrooms, dressing rooms, bedrooms).
Domestic, Marital & Infidelity Investigations
Alabama remains an at-fault divorce state, meaning evidence of adultery has direct evidentiary value. PIs commonly document timestamped meetings between a subject and a third party, hotel entries/exits, and patterns consistent with infidelity. Photographs taken in public are admissible. PIs must avoid accessing a spouse's separately maintained accounts or devices, as Alabama's computer-crime statute treats such access as unauthorized.
Cybersecurity, Hacking & Digital Investigations
The Alabama Computer Crime Act (Code §13A-8-100 et seq.) criminalizes unauthorized access to any computer, network, or data. The federal CFAA (18 U.S.C. §1030) applies in parallel. Investigators may collect open-source intelligence (public social profiles, court records, business filings) freely but must not pretext to obtain protected information, recover passwords, or access cloud-stored content without authorization.
Missing Persons, Skip Tracing & Harassment
Skip-tracing data may be sourced from commercial aggregators (LexisNexis, TLO, IRB) under the Driver's Privacy Protection Act (18 U.S.C. §2721) only with a permissible purpose. Alabama recognizes a stalking statute that PIs must respect: persistent, threatening contact even in pursuit of a legitimate investigation can cross the line. PIs may not serve civil process unless additionally registered as a process server in the relevant county.
