Using a real estate agent or a real estate lawyer

In need of advice BP community. I recently located a property, talked with the owner and made an offer. The owner lives out of state so their property manager walked me thru the property. Later me and the owner talked again and we agreed on a price. The property manager presented paperwork to act as a dual agent. However, the owner prefers going straight thru our lawyers. In that case, I would have to pay the commission to the agent/property manager if I decided to use him. This is my first time being in this situation. Not sure if I should entertain keeping and paying the property manager/agent or just go thru lawyers, which the owner prefers. Thanks in advance.
