Selling a Property For Sale By Owner

If I'm selling a property For Sale By Owner, can I ask the buying agent to handle my side of the paperwork as part of their commission, or is the agent going to charge an additional fee for that? And is this a bad idea in general...i.e. do I need to hire someone like an attorney or another agent to look out for my best interests? FYI, the Agreement of Sale is already done, and I don't have a mortgage, so it should be a simple transaction on my end...

Thanks!
