You need to use a closing company to handle the paperwork and the money. If the TS is in Hawaii, a licensed Hawaiian escrow company must hold the funds. See the "how to sell a TS" article at the top of the forum, and also click on the ADVICE link in the red bar at the top of the page for a wealth of info.
Note that traditionally, the buyer pays for closing and chooses the company, so you should consult with them. If you are paying, you get to choose. Generally a full closing costs around $350.
If there is little or no money involved, then you don't need all the bells and whistles. I recommend this licensed Document Prep Co. that can prepare the deed and send it for recording for about $100. The owner (Alan) is a long-time TUG member - user name "ttt". They have an "A" rating in the TUG Business Ratings -
