Preparing for Eviction - Montgomery County, PA

[Scott Seydor]

Seems as though I've got a tenant that has to go.  Guy looked great on paper, but that quickly all went to hell.  In three months, rent has been late twice, he's refusing to pay the July late fee, police have been there three times for disturbing the peace and I'm fairly certain he's got a roommate living with him (he denies it) that isn't on the lease.  He's in one half of a duplex and has my other tenant (who is great) upset about the noise.  I'm new at all of this and haven't ever evicted anyone.  I started doing my homework on the Mongomery County, PA website and everything I found there is tailored to the tenant's perspective (what to do if you're being evicted and legal help on how to fight it).

Can anyone out there help me with the specifics of what I need to do?  Pennsylvania insights would be great, and Montgomery County (Pottstown, PA) would be even better.
