As stated above, the cost of doing what you want will be very high because it is in the Bahamas. And most of the timeshares in the Bahamas will be very difficult to sell (or even give away for free) except for a few (very few) high- end resorts such as Harborside at Atlantis.
Before you go "throwing good money after bad," research what the going resale price is for what you own at this resort. If it seems to have some resale value, would the seller be willing and able to sign the necessary papers to transfer ownership if you found a buyer? No sense doing it twice.
If you are unable to sell the week and will be stuck with the on-going maintenance fees, you need to have a serious discussion with the person you bought it from. Is he willing to leave things as they are? He would probably be ultimately responsible for the maintenance fees if you failed to pay them.
If he wants to have it totally out of his name, tell him you feel he should pay the cost of recording the deed. Am I correct in assuming that if you knew the costs of deeding would be so high, you might not have bought it at all, or the price you agreed upon would have been lower? If he is not willing to pay the full costs, maybe you would want to suggest splitting it 50/50.
I hope you haven't grossly overpaid for what you own. A lot of times a prior owner has no idea what the going price is now for something they bought directly from the developer at an exorbitant price. You will both know the proper price after doing research at
www.redweek.com (no cost to sign in as a guest) and
www.myresortnetwork.com and Ebay
www.ebay.com. It could be zero
You should also go to
www.donateforacause and see if your week is on the list of timeshares they will not accept as a donation.
If you paid too much, see if you can undo the sale--receive a refund and sign it back to him, or maybe let him keep all or half of the money you gave him, in return for getting out of this thing altogether. The way the resale market is these days, one can buy high value weeks for well less than $1,000. including all closing costs.
You could try posting the name of the resort and the type of ownership (fixed deeded week, floating (which season) or a RTU (right to use). We would then be able to give you better advice re:salability. However, your post
might be deleted if the Moderator considers it an "ad" which is not allowed on these forums.
