The form in the back of the directory, Membership Transfer Application, is
> mainly used for the sale of timeshare, but also for the transfer of weeks.
> The most important parts of the document are the areas which indicate your
> account information, the week you want transferred, and to what account
it's > going to. As long as we have that information along with your signature,
it should be taken care of. That information can also be listed in a signed
> letter if you prefer. Once the information is completed, you can fax it
to us at 317/805-9335 if you wish. Hope this helps.
