It appears the prosecutor is assisting you,and therefore you need to check with your contact there.
On the other hand, the way support normally works is that it will be retroactive from the date of filing, of the case or the motion so the ultimate result remains the same so, ultimately, there is no gain from a delay of the motion hearing.
To the PROSPECTIVE client, please call myself or another attorney for you choice with more detaiils and an appointment. My PRELIMINARY answer to your question(s) is for general purposes and based upon what little information you have conveyed. It is based on such limited information that the general answer should never be relied as a reason for your action or inaction. My response does NOT establish an attorney-client relationship and such may only be established by mutual agreement, and the signing of a written retainer agreement, which will generally require payment for our services, as this is what we do for a living and, just like you, we must get paid for our work.. .
