WHERE can I get affidavit of service for Cabarrus County

Hi…I had legal aid send me a do it yourself divorce kit. All has gone smoothly except I can’t find one of these forms ANYWHERE. I have my green receipt from where my husband picked up the papers, but nothing to attach it to? And I’ve searched online and the only one I can find is one about child support/child custody and that’s not what I want. I have a certificate of service paper…is that the same thing? This is driving me crazy.

The affidavit of service is AOC form number AOC-CV- 662 and can be found here:
