I'm not sure about this one. We have bought in directly at DVC in 2019 and there was no additional paperwork needed for that. However, a couple of months later DVC sent us a W8BEN form, so I would expect that you would receive one from DVC if you are a new owner. But it would not influence the process of buying into DVC. I think you should ask the resale company to clarify this, but my bet is that as an international buyer there is no additional paperwork and are no additional costs. FWIW, we are buying a resale contract right now (international buyer as well) and there is no additional paperwork that I can remember of.
