There are certain exceptions, but yes, most of all court cases are public. If anyone wanted information about a court case, they can often get the case files from the court clerk.
There are currently three exceptions that would make your court case private.
1. If the type of case itself is a confidential case, then the files are private as well. Some examples of this would be a juvenile case or an adoption case.
2. Some files are kept confidential such as child custody assessment and recommendations. Only certain people are have access to these files and their information.
3. On occasion, a file can be sealed by the courts if it was requested and if it was granted by the courts. Once this occurs, only a certain about of people will be have access tot he files and information, specifically the parties involved in the court case. This might be requested because the files may contain private financial information about the persons involved or highly sensitive materials.
