Just had the same thing happen to me. Googled info.
Vacated, means it was never legal in first place. So in both my case and yours, the judgement was not vacated---it was just paid.
In my state, you have 180 days from the date you are served to file for vacated judgement. Didn't know then. Didn't matter. I really owed it.
I 'may' have tried to get it 'dismissed', but too late now.
Again---just because it's paid, doesn't automatically make it vacated or dismissed, because are two entirely different scenarios.
