Notice of Hearing

I have completed a Motion for Modification of Child Support Order today and have a court date of June 13 (Union County, NC). When do I have to give the Defendant a copy of the notice? I would prefer to wait until May 10 and hand it to the defendant. Is that acceptable? Should I have the Defendant sign the Centtifcate of Service on the back? It justs says Name of Person With Whom Copy Left. How do I prove I gave it to the Defendant?

Motions need only be mailed, via regular US mail. Send it to the Defendant now, with a certificate of service showing that you mailed the same, to what addresses and on what date. It sounds like you are attaching a Summons to the Motion, which is not necessary, those are only issued when a new Complaint (initial action is filed).
