Am I able to put on live testimony (call witnesses) at my Request for Orders hearing?

If you intend to put on live testimony other than the parties to the action, you must provide written notice to the other party of the person you desire to testify along with a brief summary of what they intend to testify about. Failure to provide such notice will preclude you from calling any witnesses. However, just because you list a witness does not guarantee that this witness will actually testify as this decision rests on the judicial officer making a determination of whether the information provided will be probative in making a decision regarding custody and visitation. In addition, the court could continue the matter for a later date (as time may be limited on the scheduled hearing date) which likely result in temporary orders being made pending the next court date.
