Have you both been following the weekday/weekend schedule that was noted in the time share plan modification? Was the child support calculations based on the correct schedule? Is your ex going to testify truthfully about what the timeshare agreement is if asked by the Judge? If the answer is yes to all questions then it sounds like you have nothing to worry about at the upcoming hearing. If you understandably want to make sure the order reflects all necessary information and reflects the actual agreeement, then it's not too late to change the order. Since you are more than likely going to see the same Judge and I am assuming you used a boilerplate docment with blanks in it because you said you did not 'fill in the section,' you may be able to get the Judge to fill it in if both you and your ex acknowledge the ommission at the next hearing. However, the proper way to go about would be a petition to modify or if your case is currently open a motion to modify the order to correct the ommission.
