If you mean the buyer will need to pay 2020 dues to DVC in addition to your having already done so, then your understanding is incorrect. DVC wants any outstanding 2020 dues paid at time of closing, but if they are already fully paid, the issue becomes one solely between the buyer and seller. As part of any agreement, the parties could agree to have the buyer reimburse all 2020 dues, pay a pro rata portion with the seller absorbing the portion applicable to the time before closing, or simply agree to a per point selling price that reflects some addition for dues already paid, or a portion thereof. What is important is to make sure the issue of dues and what the seller expects to be done on the issue is put up front so the buyer knows before making an offer on the contract.
Also, even if the buyer agrees to reimburse some dues, that will not be done as some separate transaction but, instead, will be part of the closing and part of the total amount paid the seller, out of which will come the broker's agreed fee before payment to the seller..
