An individual who has met Illinois training, experience, and examination requirements and holds a valid state license to conduct investigations for hire. The license is personal and may not be transferred or used by another person.

A credential issued to a person who works for a licensed private detective agency but does not independently hold a detective license. The registration is tied to the employing agency and permits the person to perform investigative work under that agency's authority.

A card issued by the state to identify an individual who is registered to work in a regulated private security, alarm, or detective capacity. The holder must carry the card while on duty and display it on request of a client, employer, or authorized state official.

A credential authorizing a person or business to perform locksmith services such as installing, repairing, opening, or rekeying locks for compensation. Illinois requires licensing for locksmiths and regulates advertising, identification, and recordkeeping of service calls.

A license issued to a business that captures and submits fingerprints for criminal history background checks or other authorized purposes. Vendors must use approved equipment, protect biometric data, and follow state transmission and retention rules.

The Illinois state agency that administers professional licensing, including the private detective, security, alarm, locksmith, and fingerprint vendor programs. It investigates complaints, conducts disciplinary proceedings, and adopts administrative rules implementing the governing Act.

Regulations adopted by a state agency to carry out the statute it administers. In this field, rules set details such as training curricula, application procedures, recordkeeping formats, and disciplinary procedures that licensees must follow alongside the Act itself.

A mandated number of approved instructional hours a licensee must complete during each renewal cycle to keep a credential active. Topics typically include legal updates, ethics, and technical skills; proof of completion must be retained and produced on audit.

The periodic process by which a licensee applies to extend a credential before its expiration date, paying fees and showing compliance with continuing education and other requirements. Practicing on an expired license is unlawful and can lead to discipline.

Penalties the state may impose on a licensee for violations, ranging from reprimand and fines to probation, suspension, or revocation of the license. Grounds include fraud, unlicensed practice, criminal convictions, and failure to cooperate with an investigation.

Performing services that legally require a state credential without holding that credential, or aiding another person in doing so. It is a violation subject to civil penalties and may also constitute a criminal offense under Illinois law.

A state-issued authorization that permits a qualified security employee to carry a firearm while on duty. It requires firearms training, a background check, and agency sponsorship, and it must be carried with the employee registration card.

The minimum pre-assignment and annual in-service instruction a security employee must complete, covering topics such as report writing, emergency response, and legal limits on authority. Completion must be documented by the employer and available for state inspection.

The duty to keep information learned during an engagement private and to disclose it only as authorized by the client or required by law. It survives the end of the engagement and applies to employees, subcontractors, and anyone with access to case files.

A practice of limiting access to case information to persons who require it to perform their assigned duties. It reduces the risk of leaks, protects the client, and supports the argument that the investigator exercised reasonable care over sensitive data.

A client's documented authorization permitting the investigator to release specified information to a named party. Best practice is to record the scope, purpose, recipients, and expiration so the investigator can later show the disclosure was lawful and intended.

A court-issued command requiring a person to appear, produce documents, or both. An investigator who receives one should verify its validity, notify the client and counsel where appropriate, and preserve responsive records rather than destroy or alter them.

Information protected from forced disclosure because of a recognized relationship, such as attorney-client. An investigator hired by an attorney may be covered by the attorney's work product protection, but the investigator should never assume privilege without confirming with counsel.

Materials prepared in anticipation of litigation that receive qualified protection from discovery. Investigators engaged by counsel should label reports and notes appropriately and route communications through the attorney to help preserve the protection.

Systematic observation of a person, place, or activity to gather information, conducted from a fixed position or by following a subject. It must stay within lawful limits, avoiding trespass, stalking, and prohibited interception of private communications.

Following a subject on foot or by vehicle to document movements and associations. The investigator must maintain a safe distance, obey traffic law, avoid detection where lawful, and be prepared to terminate the follow if it becomes unsafe or compromised.

Observation conducted from a fixed location such as a vehicle or rented room. Success depends on site selection, concealment, a clear view of the target area, and continuous logging of times, conditions, and observed events.

A contemporaneous written record of observation times, locations, weather, activity observed, and the investigator's actions. Entries should be factual, sequential, and free of conclusions so the log can support later testimony or reporting.

A documented, unbroken record of who handled evidence, when, and for what purpose from collection through final disposition. Gaps or inconsistencies can undermine admissibility and credibility, so each transfer should be signed and dated.

A register listing each item collected, its unique identifier, description, location found, collector, and storage location. It works with the chain of custody to show that the item offered in a proceeding is the same item originally gathered.

The loss, destruction, or material alteration of evidence that a party had a duty to preserve. It can lead to sanctions, adverse inferences, or malpractice claims, so investigators must suspend routine deletion once litigation is reasonably anticipated.

Practices that keep original evidence intact and usable, such as photographing before moving items, using evidence bags, maintaining climate-controlled storage, and making forensic copies of digital media rather than working from originals.

Notes made at or near the time of an event, capturing facts before memory fades or is influenced by later information. They support accurate reporting and may be discoverable, so they should be clear, dated, and retained under the case retention policy.

Preparing a factual, organized account of investigative activity for the client or counsel, typically including scope, methods, findings, and supporting exhibits. Reports should separate observation from opinion and avoid speculation or unnecessary personal data.

The organized collection of notes, reports, recordings, photographs, and correspondence for an engagement. It should be indexed, stored securely, and retained or destroyed according to a written policy and any legal hold.

A written schedule stating what records are kept, for how long, in what form, and how they are destroyed. It should account for statutory limits, contract terms, and litigation holds, and should be applied consistently to paper and electronic files.

Records of arrests, charges, and dispositions maintained by criminal justice agencies, with access and use restricted by law. Investigators may obtain it only through authorized channels and may not misuse or improperly disseminate it.

A federal law governing consumer reports, including background reports prepared by third parties for employment or credit decisions. It imposes disclosure, consent, accuracy, and adverse-action requirements that investigators performing such checks must follow.

The legal limits on physical coercion available to a private security employee, generally restricted to self-defense and defense of others. Private guards have no greater arrest or force authority than an ordinary citizen and must act proportionately.

A limited power of a private person to detain someone who has committed an offense in their presence, exercised only when lawful and safe. The detainer must promptly involve police and avoid excessive restraint to limit civil liability.

Entering or remaining on property without permission or lawful authority. Investigators and security personnel must respect posted boundaries and consent limits; pretexting entry or ignoring a revocation of consent can create civil and criminal exposure.

Intentionally confining a person without lawful authority or consent. Security personnel risk this claim when they detain someone beyond a lawful citizen's arrest or use threats to keep a person from leaving.

Safeguards for fingerprint images and other biological identifiers, including encryption, restricted access, and prompt destruction when no longer needed. Illinois law imposes specific consent and retention duties on private entities that collect such identifiers.

The service of receiving and responding to alarm signals from protected premises, including verifying signals, notifying authorities, and documenting outcomes. Contractors must follow licensing, recordkeeping, and false-alarm reduction requirements.

Documentation a locksmith keeps for each job, typically recording the date, location, service performed, and verification of the customer's identity or authority. These records help prevent unlawful entry and support compliance audits.

Verification that a person requesting locksmith work is entitled to access the property or vehicle, such as a photo ID, proof of residence, or owner authorization. Refusing service when authority is unclear protects the locksmith and the public.
