Can anyone tell me how to do an AOC from a buyer out of state??

[Eric Tunby]

Hi, I'm Eric, a wholesaler from new bern, nc. I have a property that i want to wholesale to a buyer in New York. My question is, once i send him the AOC and get it back with his signature, do i then tell him to wire half of the assignment fee to attorney here in state before proceeding forward.? Any tips are appreciated. Thanks
