Delaware All-Party

Licensing & Regulation

Delaware licenses PIs through the Delaware State Police, Professional Licensing Section, under 24 Del. C. §1301 et seq. Applicants must be 25+, U.S. citizens or legal residents, have five years of investigative or law-enforcement experience, and pass a criminal background check. Renewal is biennial.

Physical Surveillance

Public surveillance is permitted. Delaware is a small, dense state with significant suburban residential areas where curtilage doctrine is particularly relevant. GPS tracking without consent is constrained by the stalking statute, 11 Del. C. §1312.

Audio & Video Recording Consent

Delaware has a somewhat unusual posture: 11 Del. C. §2402 (wiretap statute) requires one-party consent, but the civil/criminal interception statutes at 11 Del. C. §1335 (privacy) require all-party consent for in-person conversations where a party has an expectation of privacy. Federal Third Circuit case law has treated Delaware as a one-party state for some purposes, but the safer assumption is to obtain all-party consent for any face-to-face recording.

Domestic, Marital & Infidelity Investigations

Delaware is a no-fault divorce state with equitable distribution. Marital misconduct is generally not weighed in property division but may affect alimony in egregious cases. PIs document public meetings and patterns. Online account access without authorization violates 11 Del. C. §932.

Cybersecurity, Hacking & Digital Investigations

11 Del. C. §932-941 (computer crimes) parallels the CFAA. Delaware corporate-records access is unusually broad given the state's role as the U.S. corporate capital; business filings, registered agents, and franchise-tax data are public.

Missing Persons, Skip Tracing & Harassment

Delaware State Police handle missing-persons coordination. The stalking statute (11 Del. C. §1312) covers surveillance that causes a reasonable person to fear bodily harm. DPPA fully applies.
