This collection of investigation definitions is intended to help private investigators, police officers and everyday citizens understand the meaning of various legal terms used by lawyers, attorneys, government officials, law enforcement departments, and other legal professionals.
Why These Terms are Important
During the course of their work, detectives will have interactions with police officers to discuss information contained in police reports; with attorneys and lawyers to discuss court cases and court records; and experts and specialists about such things as forensics, crime scene investigations and even handwriting analysis.
Having an understanding of the legal terms and the definitions will help private investigators “speak the language” of their craft. The more well-versed you become in the language of law, the more valuable you will become to your clients. Being able to translate legalese will help your clients feel more comfortable with you as a true expert investigator and you’ll be able to help guide them through the complexities of the legal system. It’s not your job to take the place of a qualified attorney, but you should be able to “talk the talk”.

Adultery is generally defined as the voluntary sexual intercourse between a married person and another person who is not their spouse. In the most basic sense, adultery is cheating on your spouse. In most cases, only the married party is said to have committed adultery. If both parties are married (but not to each other) then they both have committed separate acts of adultery. Adultery is also referred to as: Extramarital sex, philandering, infidelity or cheating. In addition to cheating, other slang terms include creeping, “on the down low”, sleeping around, and others.
Adultery does not include fornication. The term “adultery” carries a moral or religious association, while the term “extramarital sex” is morally or judgmentally neutral. Many would consider that a married person has committed adultery by simply having impure thoughts, or confiding in a member of the opposite sex. Some consider that a married individual who has inappropriate chats with others online is guilty of being adulterous.
A bond is a written, binding agreement to perform something as specified. Many different types of bonds exist and appear in marriage, land and court records used by genealogists. Historically, laws required administrators and executors of estates, grooms, and guardians of minors to post bonds. If a bondsman failed to perform, the court may have demanded payment of a specified sum as a penalty. Private investigators should have an understanding of bonds, as they will undoubtedly have to deal with different types of bonds during the course of their work. Investigators who offer bounty hunting services will need to be familiar with bail bonds and bail bondsmen. There will be a bail bond associated with every fugitive you are hired to track and retrieve. In addition, detectives will themselves need to be bonded as a part of the licensing requirements in most, if not every state. In this situation, it serves as insurance for a third party, such as state in which the private eye is licensed. It serves as a way of insuring that the licensed individual properly complies with state laws, statutes and rules and regulations of their trade. The cost of obtaining a bond varies from state to state, term periods, coverage amounts and whether you are an individual or a full-service agency. Do a Google search to find local companies that offer insurance services in this area. See also Bail Bonds and Bail Bondsman.
Burglary is a crime that is defined as the illegal entry into a building or home for the purposes of committing an offense or committing a crime. Usually the offense committed during burglary is the theft of property. Burglary is one of the most common crimes in the United States. Individuals burglarize homes, cares, businesses, storage units, and more. Stolen items are often sold at pawn shops or via online marketplaces such as eBay. The crime of burglary consists of two elements: trespass and breaking. The trespass element indicates the an individual’s presence on the property (car, storage unit, etc.) is without the owner’s consent. In other words the thief did not have permission to enter. The breaking element consists of making an opening to enter the building. To commit a burglary is to burgle or to burglarize. Other common names for burglary include: Breaking and entering, Housebreaking, Break-in, Home invasion.
The punishment for burglary is usually imprisonment. The term of the imprisonment depends on the degree of severity of the burglary. Greater penalties are given if the burglary involved deadly weapons or if persons were injured as a result of the crime.
In criminal law, a conspiracy is defined as an agreement between two or more persons to break the law at some time in the future. In other words, they “conspire” to commit a crime together. In some cases, a conspiracy requires there to be at least one overt act in furtherance of the agreement to commit a crime. Examples of such acts of furtherance include the purchase of supplies or materials, visiting or “scoping” the location, or documenting plans for the act. However, in most countries, there is no requirement that any steps be taken to put the conspiracy plan into effort for it to be considered unlawful. There is no limit on the number of people who might participate in the planning or execution of the conspiracy. In some situations, only two people are required to qualify. In others, small groups or even organized gangs may be involved. In other situations, entire organizations or even military organizations could be involved in the planning and execution of the act. Conspiracies can take place in relation to any situation. In some cases, the conspiracy may be harmless. Such as a group of employees who conspire to pull a practical joke on a co-worker. However, in most situations, conspiracies are considered to be of a sinister nature and intended to cause harm. Most conspiracies are centered around anti-government or anti-military behavior.
Copyright infringement (or copyright violation) is the unauthorized use of material that is covered by copyright law, in a manner that violates one of the copyright owner’s exclusive rights, such as the right to reproduce or perform the copyrighted work, or to make derivative works. For electronic and audio-visual media, unauthorized reproduction and distribution is occasionally referred to as piracy.
If you need to research copyright laws, the best place to start is the U.S. Copyright Office. The U.S. Copyright Office website is an excellent resource for learning and understanding copyrighting and related laws. The United States Copyright website provides an overview of copyright basics, information on the law, and a list of FAQs. You can also Search the Catalog of records of registered books, music, art, and periodicals, and other works. Includes a review of ownership documents. Private investigators are sometimes hired to investigate such cases. A detective’s primary role in such cases is to gather evidence and proof of infringement.
Detention, or detaining, of suspects is the process of keeping a person who has been arrested in a jail cell, prison or other detention center before their legal trial or sentencing. Such buildings are often referred to as detention centers or detention facilities. People can also be detained illegally or against their will. In this situation, crimes such as kidnapping or unlawful arrest may occur. Private detectives may deal with cases that involved individuals that have been detained. Detectives may need to travel to prisons, county jails or other detention facilities to interview witness and suspects to gather information for a case. In some situations, a private detective may need to physically restrain an individual until the police or other law enforcement officials arrive. This is a rare circumstance, but it certainly does happen. It is important to note that a private eye does not have any powers of arrest. See also Kidnapping.
False imprisonment is a tort, and possibly a crime. It involves a situation where a person or multiple persons are intentionally confined by another person or persons without legal authority. It entails the restraint of an individual or the obstruction of their freedom without their consent. The imprisonment of another can take many forms, such as:
- Being tied to a chair or other immovable object
- Being locked in a room
- Being locked in a car
- Being physically held or restrained
The elements of false imprisonment usually involves:
- The person detained is being held against their will
- The imprisoned person is unable to move about freely
- Proof can be provided that the imprisonment was not lawful
False imprisonment can be applicable to private situations as well as government.
Although punishment may vary from country to country, and even state to state, it is generally considered to be a 3rd degree felony, which carries penalties such as: Up to five years in jail, a fine of up to $5,000, probation, community service, other penalties as defined by the court. If false imprisonment can be proved, damages may be awarded in civil court.
The term false arrest is sometimes used in relation to false imprisonment, but it actually has a different meaning. Under a false arrest, one person arrests another, but the arresting person does not have legal justification or legal authority to do so. If the arresting person takes the other into custody and restricts their freedom, then it also becomes false imprisonment.
Nolo contendere is a Latin legal term that simply stands for “I do not wish to contend.” Nolo contendere is also referred to as a plea of “no contest” and is often referred to as “pleading nolo.” In criminal court trials, Nolo contendere is a legal plea made by the defendant who does not admit to committing a criminal charge, nor do they dispute the charge. Entering such a please is considered to be an alternative to pleading to be specifically guilty or not guilty to the criminal charge. A no-contest plea, which is technically not a guilty plea, is often offered as a part of a plea bargain deal from the prosecutor. It is not always an option to enter such a plea. The state law in which the crime was committed will determine whether the defendant may plead no contest in criminal court cases, so consult your state and local lwsuitaws to confirm. For more information on the topic, visit http://en.wikipedia.org/wiki/Nolo_contendere.
A lawsuit is a civil action brought in a court of law in which a plaintiff, a party who claims to have incurred loss as a result of a defendant’s actions, demands a legal or equitable remedy. The defendant is required to respond to the plaintiff’s complaint. If the plaintiff is successful, judgment will be given in the plaintiff’s favor, and a variety of court orders may be issued to enforce a right, award damages, or impose a temporary or permanent injunction to prevent an act or compel an act. A declaratory judgment may be issued to prevent future legal disputes. A lawsuit may involve dispute resolution of private law issues between individuals, business entities or non-profit organizations. A lawsuit may also enable the state to be treated as if it were a private party in a civil case, as plaintiff or defendant regarding an injury, or may provide the state with a civil cause of action to enforce certain laws.
- The conduct of a lawsuit is called litigation
- One who has a tendency to litigate rather than seek non-judicial remedies is called litigious
Paralegal is a term used to describe people who assist lawyers in their legal work. The profession originated as an assistant or secretary who provided assistance to lawyers with legal matters, research and related matters. Paralegals are not lawyers, but generally do have knowledge, education and even certification in legal matters and law.
- Paralegals are not authorized by the government to offer legal services such as those provide by an attorney or lawyer
- They are not considered to be officers of the court (i.e. considered a formal part of the legal system)
- They are not usually subject to government or court-sanctioned rules of conduct
- They work under the direct supervision of a lawyer
Although most jurisdictions recognize paralegals, there is no international consistency regarding the definition, role, status, terms and conditions of employment, paralegal training, regulation or anything else and so each jurisdiction must be looked at individually.
In the United States, solicitation is the name of a crime that consists of a situation where a person offers money or something else of value in order to incite or induce another to commit a crime with the specific intent that the person solicited commit the crime. Basically, it is convincing someone else to do something illegal. This can be accomplished in a variety of ways. Other definitions of Solicitation include: To entice or incite to take evil or illegal action; To approach or accost (a person) with an offer of sexual services; To make solicitation or petition for something desired; To approach or to accost someone with an offer of sexual services in return for financial. Situations involving solicitation are most common in relation to prostitution. Prostitutes are said to have “solicited” sex.
Statute of Limitations
A statute of limitations is a legal statute in that sets forth the maximum period of time, after certain events have occurred, that legal proceedings based on those events may be initiated. Basically, what this means is that after a certain length of time, you may not be able to sue someone in a court of law if the limitation has been exceeded. Also, someone may not be prosecuted for a crime after the period has expired. In civil law systems, similar provisions are usually part of the state, city or county civil code or the criminal code and are often known collectively as “periods of prescription” or also “prescriptive periods.” Statutes vary from state to state and depend on the particular situation, so check your local laws to determine what applies in the area in which your case resides. Private detectives, police officers and legal researchers should be familiar with statutes of limitation laws for certain investigation cases. In some situations, it may not make sense to accept a case if the statute of limitations has been exceeded.
Legal testimony – legal testimony is a form of evidence that is obtained from a witness who makes a solemn statement or declaration of fact. Testimony may be oral or written, and it is usually made by oath or affirmation under penalty of perjury. Unless a witness is testifying as an expert witness, testimony in the form of opinions or inferences is generally limited to those opinions or inferences that are rationally based on the perceptions of the witness and are helpful to a clear understanding of the witness’ testimony.
Expert testimony – An expert witness provides their opinion about facts and conclusions within their field of expertise.
Private investigators are sometimes called upon to testify in a court of law. They may be summoned to provide evidence and testimony regarding information they uncovered during the course of an investigations. Private eyes find themselves testifying in court in relation to divorce investigations and marital infidelity.
