The definition of adultery is subject to change based on the Family Courts in whichever state you reside. South Carolina, as with many other states, uses a two-pronged test to rule on allegations of infidelity divorce cases. What this means is, to have the court agree that you had an unfaithful partner, you must prove two things – that your spouse had a motive or inclination as well as an opportunity to cheat. To come out of court proceedings with a judgement in your favor, it is paramount that evidence to prove motive and opportunity are not only collected and documented, but also presented in an appropriate way. It is particularly important that you have the most accurate documentation of evidence as it can help courts address alimony and property division when the divorce is final. Sharp Investigations has an excellent track record of providing all necessary elements to Family Court to ensure our clients come out on top.


Every case is different, and we are wholeheartedly dedicated to getting you the verdict that protects your family, and that you deserve. Many clients ask, how long it takes to catch a cheating spouse – and the answer is that it varies depending on your particular circumstances. When working with our team of highly recommended investigators, most cases are expected to take 3-4 weeks to collect and document the evidence you need. Our licensed investigators will communicate regularly with you and will get the job done right. We promise to work discretely to protect your family’s privacy and reputation, and most importantly, make this process as easy as possible.
