ARIN legacy block transfer process

I'm trying to find a place on ARIN's website where this is addressed, but coming up short. I'm not the seller or buyer in this, but basically someone has a legacy block allocated by Postel and wants to sell the block as it's an owned asset. What's the process to get ARIN to move the admin/ownership of this? Do they only need to see a valid asset purchase agreement? There is no legacy RSA for this. I'm thinking of referring both parties to an experienced broker as well. Does anyone have current process experience with this? -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net
