Need to serve a tenant in an amended eviction suit where I am asking for $$. How do people go about serving? I know where he works--public hospital, and I know he can be served at work by leaving summons with a supervisor or personal assistant but process service company says it's impossible to get past security to do so.
I'm pretty sure he works nights so I could hang around the entrance when he's going to or leaving work but I'm looking for tried and true service advice.
In case anyone is wondering, in Denver, posting a summons and complaint on a tenant's door is not adequate for a money judgment, it can only result in possession. A money judgement requires personal service.
