If you are an individual, suing a defendant with a mailing address in Hauppauge, for money damages only, you may file your small claim in any of the 5 district court courthouses. See nycourts.gov/suffolkdistrict and look for small claims forms.
Check the website, but I think <$5000 is small claims court, might want to search of the is a closer one to the defendant, I think that's the criteria. The should be forms on the website as well, make sure you have paperwork for your case.
