We are an established Private Investigation firm since 1967 that you can trust. Offering affordable cost for Private Detective work in Chicago, Illinois.


Chicago Private Investigator


A private investigator in Chicago must apply to the Illinois Department of Public Safety and pass licensing requirements, including a thorough background check. While many Chicago private investigators come from a law enforcement or military background, it is not a requirement for employment as a private investigator. Often times a degree in Criminal Justice or other security and investigation work can be just as important to prospective employers. In the State of Illinois, it is against the law to provide the services of a private investigator without a Illinois Private Investigator License. You can rest assured that any Chicago private investigator assigned to your case with ICS is an authorized contractor, fully licensed and insured in accordance with Illinois State Laws and participates in the required continuing education.

Adultery, Infidelity or Cheating Spouse Investigations

If your spouse or significant other is cheating, you deserve to know the truth. As difficult as it may be to come to terms with the fact that your loved one is having an affair, you are going to need to get all the facts and protect your interests and well being. Coping with infidelity is not easy, but living with it is worse. A private investigator at ICS in Chicago can help you determine whether or not your loved one is being unfaithful with a Chicago Adultery, Infidelity or Cheating Spouse Investigation. Some common signs of cheating are: excessive or discreet use of the computer, spending more time at work, hiding their phone, credit card, or bank accounts histories, excessive arguing of facts related to time, blaming, defensive behavior, negative projections behavior - accusing you of an affair, lack of sexual interest or abnormal renewed sexual interest, abnormal call activity at the home or cell phones - hang ups and long tones, removal of pictures or photos from wallet, lost wedding ring, etc. If your spouse or loved one is exhibiting some or all of the common signs of cheating, you should contact ICS today to begin a case and discover the truth. Our Chicago infidelity private investigators will conduct a thorough investigation of the suspected cheater and provide you with our findings so that you can make the most informed decision for your future.

Child Custody, Visitation, and Support Investigations

The most important factor in determining the custody of a child is the child's welfare. The best interest of the child is evaluated by a court based on a set of guidelines to ensure the child has a safe, healthy, loving and stable environment. Once custody has been determined, visitation arrangements are made for the parent without custody. Although it is important, normally, that each parent or known guardian remain a strong part of a child’s life, it is equally important that your child not be in an unhealthy environment. If you believe that the best interests of your child are not being met with the current child custody or visitation arrangements, ICS can help you in your efforts to prove your case, documenting the evidence to support your claim, with a Chicago Child Custody Investigation. During the course of a child custody or child visitation investigation, ICS may interview friends, neighbors, relatives, school employees, doctors and day care workers.

State and local Child Support Enforcement Agencies in most jurisdictions are mandated under law to enforce court orders and collect child support. Typically, these agencies are understaffed and limited in their ability to find deadbeat parents and hold them accountable. In addition, the government’s investigative techniques are both predictable and superficial, and deadbeat parents quickly learn how to live beneath the radar and avoid being located. Fortunately, the private investigators at ICS are better equipped to quickly locate, and build a case against a deadbeat parent. ICS will use methods such as surveillance, hidden asset checks, public records searches, skip-tracing, undercover operations and others services in a Chicago Child Support Investigation.

Missing Person and Locate Investigations

Traditionally, it is seen as law enforcement's job to locate missing persons, especially in the case of a kidnapping. However, police and other law enforcement officers are restricted by regulations and resources, and in some cases will not even consider someone as a missing person, even though you may. In addition, police will only take on a case to locate a person if a crime has been committed. If you are searching for a lost loved one, and old friend from school, a debtor that owes you money, or other lost person, you will need to turn to a private investigator rather than the police to begin an investigation. ICS can assist you with a Chicago Missing Person or Locate Lost Person Investigation to discover the whereabouts of someone who is not easy to find. ICS can also perform a Birth Parent Locate Investigation in Chicago on your behalf. If you need to locate a lost or missing person, and need results that you can't obtain elsewhere, contact ICS to begin your case.

Background Check and Pre-Employment Screening

Do you need a background check performed on an individual in the City of Chicago? Are you in Chicago and need a background check performed elsewhere? ICS can provide this service and many others. Background checks are one of the most well known and useful investigation tools a private investigator can provide. Sometimes a background check is all a client needs and other times it is merely the first step into a more in-depth investigation, providing clues and leads for the investigator and client to pursue. Background checks are also an important part of the Pre-Employment Screening Services offered by ICS. If you need Pre-Employment Screening services, a background check or an investigation involving one, the professionals at ICS are ready to work for you to provide the discreet and confidential service you need. ICS has been helping people in Chicago just like you get results since 1967.
