Small claims after eviction

[JP Krueger]

Hi BP, I recently evicted a tenant for non payment of rent and I received a judgement for them for about 4k. 

When I take the tenants to small claims court, how do I figure out their current residence?

If there are multiple tenants on judgement, do I file one form against all three? And do i file it in a town that at least one of them resides in?

Is there a way to avoid small claims since I already have the judgement? 

Any help would be greatly appreciated.
