A private investigator (often abbreviated to PI and informally called a private eye), a private detective, or inquiry agent is a person who can be hired by individuals or groups to undertake investigatory law services. Private investigators often work for attorneys in civil and criminal cases.

Much of what private investigators did in the early days was to act as the police in matters for which their clients felt the police were not equipped or willing to do. Official law enforcement tried many times to shut it down. In 1842, police arrested him in suspicion of

. Allan Pinkerton hired Kate Warne in 1856 as a private detective, making her the first female private detective in America. A larger role for this new private investigative industry was to assist companies in labor disputes. Some early private investigators provided armed guards to act as a private militia. During the union unrest in the US in the late 19th century, industrialists would hire Pinkerton agents as undercover operatives to infiltrate and disrupt union activity or serve as armed guards for factories. In the aftermath of the Homestead Riot of 1892, several states passed so-called "anti-Pinkerton" laws restricting the importation of private security guards during union strikes. The federal Anti-Pinkerton Act of 1893 continues to prohibit an "individual employed by the Pinkerton Detective Agency, or similar organization" from being employed by "the Government of the United States or the government of the District of Columbia." Pinkerton agents were also hired to track western outlaws

cases. Others are insurance investigators who investigate suspicious claims. Before the advent of no-fault divorce, many private investigators sought evidence of adultery or other conduct within marriage to establish grounds for a divorce. Despite the lack of legal necessity for such evidence in many jurisdictions, according to press reports, collecting evidence of spouses' and partners' adultery or other "bad behaviour" is still one of their most profitable undertakings, as the stakes being fought over now are child custody, alimony, or marital property disputes. Private investigators can also perform

Responsibilities

Private investigators also engage in a variety of work not often associated with the industry in the mind of the public. For example, many are involved in process serving, the personal delivery of summons, subpoenas, and other legal documents to parties in a legal case. The tracing of absconding debtors can also form a large part of a PI's work load. Many agencies specialize in a particular field of expertise. For example, some PI agencies deal only in tracing. A handful of firms specialize in technical surveillance counter-measures, sometimes called electronic counter measures, which is the locating and dealing with unwanted forms of electronic surveillance (for example, a bugged boardroom for industrial espionage purposes). This niche service is typically conducted by those with backgrounds in intelligence/counterintelligence, executive protection, and a small number from law enforcement entities whose duties included the covert installation of eavesdropping devices as a tool in organized crime, terrorism and narco-trafficking investigations. Other PIs, also known as corporate investigators, specialize in corporate matters, including antifraud work, loss prevention, internal investigations of employee misconduct (such as Equal Employment Opportunities violations and sexual harassment), the protection of

Undercover investigator

An undercover investigator, undercover detective, or undercover agent is a person who conducts investigations of suspected or confirmed criminal activity while impersonating a disinterested third party. Undercover investigators often infiltrate a suspected insurgent group, posing as a person interested in purchasing illegal goods or services with the ultimate aim of obtaining information about their assigned target. Many undercover investigators carry

s and recorders strapped to their bodies to help them document their investigations. The period of the investigation could last for several months, or in some extreme cases, years. Due to the dangerous nature of the job, their real identities are kept secret throughout their active careers. Economic investigations, business intelligence and information on competitors, security advice, special security services information, criminal investigation, investigations background, and profile polygraph tests are all typical examples of such a role. Certain types of undercover investigators, depending on their employer, will investigate allegations of abuse of workman's compensation. Those claiming to be injured are often investigated and recorded with a hidden camera/recorder. This is then presented in court or to the client who paid for the investigation.


Across the world

Many jurisdictions require PIs to be licensed. Depending on local laws, they may or may not carry a
firearm A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes ...
. Equipment can vary greatly, but generally involves a wide variety of surveillance equipment and recording devices. While PIs may investigate criminal matters, they typically do not hold any law enforcement authority by virtue of the position, regardless of licensure. Private investigators’ authority is usually identical to other citizens’ (off-duty or retired law enforcement officers serving as a PI may retain their police powers at all times, depending on the jurisdiction). They are expected to keep detailed notes and to be prepared to testify in court regarding any of their observations on behalf of their clients, irregular hours may also be required when performing surveillance work. Great care is required to remain within the scope of the law; otherwise, the private investigator may face criminal charges. However, there are also cases across the world, of corrupt or rogue private investigators who have obtained people's private data and information through illegal means. These include phone hacking,

Australia

Private investigators in Australia must be licensed by the licensing authority relevant to the state where they are located. This applies to all states except the Australian Capital Territory. Companies offering investigation services must also hold a business licence and all their operatives must hold individual licences. Generally, the licences are administered and regulated by the state police; however, in some states, this can also be managed by other government agencies. To become registered in New South Wales requires a CAPI licence, which can be applied for through the NSW Police Force website. The Australian Capital Territory does not require PIs to be licensed, although they are still bound by legislation. PIs working in the ACT cannot enter the NSW area without a CAPI license, else they will be in breach of the law. In Queensland, a private investigator need to be licensed under the

In 2001, the government passed the licensing of private investigators and private investigation firms in the UK over to the

(SIA), which acted as the regulatory body from then on. However, due to the cutbacks of this agency, licensing of private investigators in the UK was halted indefinitely. At present, no government-backed authorities in the UK license private investigators. The SIA have announced that PIs in the UK were to become licensed for the first time from May 2015, but this is only the scheduled date for the issue to be discussed in parliament. In December 2014, Corporate Livewire produced an article written by a UK private investigator at BAR Investigations, addressing the issues surrounding private investigation in the UK.


United States

Private investigators in the United States may or may not be licensed or registered by a government licensing authority or state police of the state where they are located. Licensing varies from state to state and can range from: a) no state license required; b) city or state business license required (such as in five states (

became the first state in the union to institute licensing requirements for private investigators, as stated in the 1877 Legislative Manual. In 1977, when El Paso County challenged a local security company's right to conduct investigations without a license, Colorado Supreme Court declared the licensing law too vague because it didn't adequately define a "detective business" and struck it down. Following this, several private investigators formed Professional Private Investigators Association of Colorado (PPIAC) in order to try to get the licensing laws reinstated, but the bills died in the General Assembly.

John Hickenlooper signed into law Colorado House Bill 1195, which reinstated licenses for private investigators on voluntary basis effective July 1, 2012. A license applicant would have to be of 21 years of age or older, hold United States citizenship and have at least 4,000 hours of work experience as an investigator or part of a local, state or federal law enforcement agency; or 2,000 hours with post-secondary education. On June 6, 2014, Hickenlooper signed into law Senate Bill 133, which effective June 1, 2015, made licensure mandatory. This split the licenses into two categories: Class I, requiring the applicant to be 21 years of age or older, hold United States citizenship and pass the Colorado Jurisprudence Exam. Class II requires in addition to Class I requirements a minimum of 4,000 hours of work experience as an investigator or part of a local, state or federal law enforcement agency.

' Office of Policy, Research and Regulatory Reform suggested licensure requirement elimination, predicting "little to no consumer harm". In June 2020, Governor Jared Polis vetoed House Bill 1207 to keep licensure requirements, causing the licensure requirements to expire on August 31, 2021. Florida has 3 types of licenses - Class CC for private investigator intern, C for private investigator, and MA for manager of a private investigative agency. As Class C license requires at least 2 years of experience, most applicants start with Class CC, which allows them to work under a sponsorship of a licensed Class C investigator. For a Private Investigator License in New York, an investigator needs 3 years of verifiable experience, and to pass a NY State Department of State Division of licensing Services exam. In 1893 a federal law was passed explicitly barring the government from employing the Pinkerton Detective Agency or a similar agency.
