Breach of contract clause and how to enforce

Hello Bigger Pockets

I wanted to ask if anyone here has ever filed for breach of contract when a tenant breaks the lease without either due notice or paying out the duration of the lease and or penalty for same.

I am considering enforcing a clause in my lease which stipulated 1.5 times the rent due for the remainder of the contract period 

I am not sure it's even worth it as I may never see the money 

I have filed for possession and I have filed for unpaid rent.

But in both those situations the tenant is usually still occupying the property.

This seems to be a bit different is it the same court ? Does the Marshall still serve the paperwork?

Is the price still the same?
