What you need to look for is a document called Notice of Entry of Judgment. The court will send you a stamped copy in the mail, usually with a stamped copy of your Judgment. Look for it. If you've found it, then great--you're divorced. You won't receive anything called a "final divorce decree" or anything like that.

The FL-180 is the Judgment in the case - what you refer to as the final divorce decree. You should also have received a FL-190 Notice of Entry of Judgment in the mail. If you didn't receive it, go to the Court Clerk's office and ask to inspect the case file, and purchase a copy of the Notice of Entry of Judgment, for your records.
