How to Become a Private Investigator in Delaware (2026)

Last updated: May 4, 2026

Private investigator licensing in Delaware is issued by the Delaware State Police (DSP) Professional Licensing Section – not the Division of Professional Regulation that handles most other Delaware trade licenses. The DSP regulates private investigative agencies (Class A), private security agencies (Class B), and combined PI/security agencies (Class C). Individual PI licensees pay a $105 application and renewal fee plus a $20 ID card fee. Delaware requires no formal training or education for individual PI licensees, which is more accessible than neighboring states – Maryland requires specific experience paths and Maryland State Police processing; Pennsylvania requires ACT 235 training. To open your own Class A PI agency, you need 5 years of investigative experience, 5 years as a police officer, or law enforcement academy graduation. Licenses are valid for 5 years and expire on your actual birthdate.

Delaware’s distinctive recording consent law creates an important operational nuance: two state statutes conflict on whether one party or all parties must consent to recording. Delaware Code Title 11 Section 2402 allows one-party consent (the standard wiretapping statute), but Section 1335 (the privacy statute) requires all-party consent and makes violation a misdemeanor. In practice, Delaware is treated as an all-party consent state. PI professionals conducting surveillance or interviews in Delaware should treat every recording situation as requiring all-party consent to avoid Section 1335 liability – even though Section 2402’s technical language would suggest otherwise.

How to Become a Private Investigator in Delaware (Step by Step)

Step 1: Understand Who Regulates Delaware PIs

Delaware’s PI licensing is administered by the Delaware State Police Professional Licensing Section, not the Division of Professional Regulation (DPR) that handles most other Delaware trades. This is an important distinction – you will not find PI licensing on the DELPROS portal. Contact DSP Professional Licensing directly: phone (302) 739-5991, email dsp-prolicense@delaware.gov.

The DSP Professional Licensing Section oversees several license categories for the security and investigation industry. The three primary agency types are: Class A (Private Investigative agencies), Class B (Private Security agencies), and Class C (Combined PI/Security agencies). Individual PI employee licenses are separate from agency licenses. You need both an individual license and employment by a licensed agency to legally work as a PI in Delaware.

Step 2: Decide Whether to Work for an Agency or Open Your Own

Working as an Individual PI for an Existing Agency

This is the entry path for most new Delaware PIs. You must be hired by (or have a firm offer from) a licensed Delaware PI agency before your individual license application can be approved. Individual PI licensees do not need prior investigative experience – the employment requirement is the gate. This is a more accessible entry than neighboring Maryland, which requires documented experience and Maryland State Police processing with specific credential evaluation.

Opening Your Own PI Agency (Class A)

To open a Class A Private Investigative agency, you must meet one of three experience requirements: (1) 5 years of investigative experience, (2) 5 years of service as a police officer, or (3) graduation from a certified law enforcement academy. New agency license applications are reviewed by the Board of Examiners at quarterly meetings – contact DSP Professional Licensing for current submission deadlines. Allow 3-6 months from complete application to agency approval, depending on meeting schedule. Class A agencies submit quarterly roster submissions of all employees to DSP (January, April, July, October).

Step 3: Meet Eligibility Requirements

Delaware requires all individual PI applicants to be at least 21 years old. No felony convictions are permitted. No misdemeanor conviction involving theft-related offenses, drug offenses, or moral turpitude within the past 7 years. Delaware does not require formal training, education, or minimum experience hours for individual PI licensees – the background check and employment requirement are the primary gatekeepers. This places Delaware among the more accessible PI licensing regimes in the mid-Atlantic region.

If you want to carry a firearm while working as a PI, you must complete a 40-hour Firearms Qualification course from a Delaware State Police-approved instructor. This is separate from any carry permit – Delaware’s procedures for armed PI work require this specialized qualification before the DSP will authorize firearms for PI work.

Step 4: Complete IdentoGO Fingerprinting

Delaware State Police requires applicants to submit fingerprints for a criminal background check. Use IdentoGO with service code 27RVQ3. Fingerprinting results are forwarded directly to DSP Professional Licensing. Allow 2-4 weeks for background check processing after fingerprinting – plan this timeline into your expected start date when negotiating your employment start with an agency.

Step 5: Submit Your Application and Pay Fees

The application and renewal fee is $105 (non-refundable). Submit in person with cash or credit card, or by certified check, company check, or money order payable to the State of Delaware. Upon approval and receipt of your ID card, an additional $20 fee is due. Replacement ID cards cost $5 (routine) or $10 (lost/stolen). Your license is valid for 5 years and expires on your actual birthdate. Renewal is required before expiration; the same $105 fee applies at renewal.

Step 6: Understand Delaware’s Recording Consent Dual-Statute Problem

Delaware has two statutes that directly conflict on recording consent, creating legal uncertainty that every Delaware PI professional must understand:

Delaware Code Title 11 Section 2402 (the wiretapping statute): Permits a person to record a communication if they are a party to it, or if one party has given prior consent. This is “one-party consent” language – the standard in most states.

Delaware Code Title 11 Section 1335 (the privacy statute): Requires consent of all parties to intercept or record private communications and prohibits installation of hidden recording devices in private places. Violation is a misdemeanor, punishable by up to one year in jail and fines up to $2,300.

Because both statutes exist, legal and practical consensus treats Delaware as an all-party consent state. Recording without all-party consent creates liability under Section 1335 even if Section 2402’s language would technically permit it. For PI professionals, the operational rule is: never record a conversation without informing and obtaining consent from all parties present. This applies to interviews, telephone calls recorded for notes, and any situation where a private communication is captured. Cross-border work with Maryland (all-party consent) and Pennsylvania (all-party consent) presents similar constraints for PI operators working throughout the mid-Atlantic region.

Step 7: Form Your Business and Get the Delaware Business License

If opening a PI agency, file an LLC Certificate of Formation with the Division of Corporations for $110. Pay the flat $300 LLC franchise tax annually by June 1. Obtain a Delaware Business License from the Division of Revenue for $75/year at onestop.delaware.gov. Delaware has no general sales tax – PI services are not subject to state sales tax. Delaware’s Gross Receipts Tax (GRT) applies to PI agency revenue at 0.3983% for service businesses, with a $100,000 monthly exclusion that most agencies never reach. Delaware personal income tax applies to LLC pass-through income at graduated rates up to 6.6%.

Step 8: Handle Insurance and Payroll

PI agency operations require commercial general liability insurance and professional liability (errors and omissions) coverage. Review the DSP’s Agency Bond Form for the specific bond requirement for your agency class. Workers’ compensation is required if you employ one or more investigators – PI workers fall under NCCI code 7720. Delaware’s minimum wage is $15.00/hour. For agencies with 10 or more employees, the Healthy Delaware Families Act PFML contribution of 0.8% of wages applies (benefits available since January 1, 2026). Report new hires within 20 days of start date.

Delaware PI Market: Demand Drivers

Delaware’s PI market is disproportionately influenced by its corporate law environment. The state’s role as the incorporation home for more than two-thirds of Fortune 500 companies generates corporate investigation work: due diligence investigations for M&A transactions, internal investigations for corporate governance, background investigations for executive hiring at Delaware-incorporated companies with local operations. Wilmington’s financial services cluster (JPMorgan Chase Delaware, Bank of America, Capital One Delaware operations) and pharmaceutical/biotech corridor (AstraZeneca, Incyte, Chemours) create additional corporate investigation demand from employers running background checks, trade secret investigations, and employee misconduct investigations.

The family law sector is a consistent PI demand driver. Wilmington’s legal community includes firms that handle Delaware corporate divorces (where corporate assets are entangled in marital dissolution) alongside conventional domestic matters. Infidelity investigations, child custody documentation, and asset searches are standard PI work in the Delaware market. Sussex County’s retiree population creates estate-related investigation demand – heir location, beneficiary verification, and Medicaid asset searches. The Dover AFB military community generates its own specific pattern of deployment-related domestic investigations.

Delaware’s proximity to Washington DC (90 miles), Baltimore (70 miles), and Philadelphia (30 miles) means many Delaware PIs also work across state lines into Maryland, Pennsylvania, and New Jersey. Multi-state licensing is common in this corridor. Verify current reciprocity terms with DSP before marketing cross-border services, and ensure you comply with the recording consent laws of each state where you work – Maryland and Pennsylvania are both effectively all-party consent states, which aligns with Delaware’s practical all-party posture.

To open your own PI agency (Class A), you need 5 years of investigative experience, 5 years as a police officer, or law enforcement academy graduation.

Is Delaware a one-party or all-party consent state for recording?

Delaware has conflicting statutes. Section 2402 (wiretapping) permits one-party consent. Section 1335 (privacy) requires all-party consent and makes violation a misdemeanor. Delaware is treated in practice as an all-party consent state. Always obtain all-party consent before recording any private conversation to avoid Section 1335 liability.

Can a Delaware PI agency work in neighboring states?

Delaware PIs often work across state lines into Maryland, Pennsylvania, and New Jersey given the state’s small size and proximity to Philadelphia, Baltimore, and Washington DC. You must comply with each state’s licensing laws – some states recognize reciprocity with Delaware and some require separate licensure. Maryland requires separate Maryland State Police licensing for PI work performed in Maryland. Verify each state’s current requirements before marketing cross-border services, and always comply with the recording consent laws of the state where the work is performed.
