How do you stop a motion for a 12 year old's testimony in a custody hearing?

To stop a motion for a 12-year-old's testimony in a custody hearing, you would typically need to file a motion with the court and present legal arguments supporting why the child's testimony should not be allowed. This could be based on factors such as the child's age or maturity level, potential harm from testifying, or alternative means of gathering the child's input through a guardian ad litem or custody evaluation. Consulting with a family law attorney would be advisable to navigate this process effectively.
