Title Company - prepares and files the Docs for the legal transfer of a timeshare.
Escrow Company - holds the funds in escrow, during the transfer.
Hawaiian Law requires you to use an escrow company licensed in Hawaii. Which applies if there are funds involved in the sale.
If you are giving away your timeshare, then there are no funds, and you don't need an escrow company, but you will probably still want to use a TS title company, to be sure the Docs are prepared legally.
