If you're a person involved in a court case or being questioned by a government official, you have the right to refuse to answer questions if your answer could get you in legal trouble. This is often called "pleading the Fifth" or your privilege against self-incrimination. It applies whether you're talking to a court, a police officer, a government agency, or any other public official, whether at the state or federal level.
This protection belongs to you personally, and you have to actually claim it. In other words, you need to speak up and say you're using this right when you're asked something you don't want to answer because it might incriminate you. If you don't claim the privilege, you could end up answering the question anyway.
This rule works alongside two other rules (K.S.A. 60-423 and 60-437), which may place some limits or conditions on how this privilege works in certain situations. So while you generally have strong protection against being forced to incriminate yourself, there can be exceptions depending on the circumstances of your case.
