Can I ask for assistance from the Police department to serve an eviction notice to my tenant?

Hello g:

Sure, but why don't you just mail it instead? I don't know which particular notice you're serving, but if you're afraid for your safety, you can hire a professional server. It might cost $50. I actually don't think the police will accompany you.. But, they might.

Especially if you promise to bring doughnuts.
