Partnership gone bad

[Steven Myers]

I am relatively new here an haven't posted but I have run accross an issue on one of my properties.

I bought a property with a partner and it is just now being rented out this month. He has more experience with rentals so I decided to let him take the lead but now he is wanting to charge me a 37.5% of the rent to find the tenants and 5% a month. I never agreed to neither fee, but I agree he should be compensated some but not at the level of a property management company because he is not that. If I would have known he was going to do that I would have leased the property myself as I have a couple of rentals. What are my options? I have tried to negotiate with him but he says it is final. Are my only options is taking him to court. Also, he put the leases in his name only and never ran the tenants by me so I have no clue who is in the property.

Thanks for any help.
