I was served a motion in Family court. The motion is set for hearing. Do i need to respond in writing, if so by when?

Unless you are going to provide the documents voluntarily to your ex, you need to attend the hearing and argue against the motion in court..

Motions do not require written responses. Sincerely, Daniel Bachert, Esq. Family Law Attorney/Mediator and QDRO Specialist

respond in writing and prepare for the hearing....and decide why you are not providing the documents

It is not required that you respond to the motion in writing. If you do wish provide the requested documents to your former spouse, you can do so and make a request to your former spouse to cancel the hearing in light of the production of items. If you choose to not furnish the items prior to a hearing, you'll need to prepare to attend the hearing. It would be in your best interest to contact a family law attorney to learn more about the appropriate course of action to defend yourself against the motion.

Although it is true that a motion does not require a written response, you are free to file such a response. However, as one of my colleagues mentioned, if you have not provided documents that you are required to provide per your settlement and final judgment, perhaps you should consider doing so in advance of the hearing.
