I bought an AKV contract several months ago and this was the VERY issue I was concerned about after reading a blog post by one of those
dvc guys (dvcfan, or dvcguy, or something like that). This happens much more frequently than the brokers would ever let on - misunderstanding or not.
The reason: Disney allows it to happen.
What should happen: the day Disney waives ROFR, the points should be verified against the written contract and the account should be frozen. Oh for a perfect world...
What actually happens: you are on your own and your broker and title will likely require you to sign a "hold harmless" document in the closing papers.
Something like this:
<<
Buyer understands that XXXXXX Title guarantees title only.
WE as a company in no way guarantee the sellers’ claims of occupancy and use of this timeshare period. Proper representation regarding the transaction is the sole responsibility of the seller.
>>
Now, as others have pointed out, there will be (or should be) clauses in the contract promising reimbursement for point discrepancies. But the seller could be long gone with your money by then. At a minimum it will be a huge stress on you and your family, with no guarantee of a good outcome.
Based on all of this, I did the following prior to closing my AKV contract:
1) I made the seller send me screen shots of their DVC dashboard the day before closing
2) I made the broker (owner of the company) put in writing that they would immediately "make whole" any points discrepancies. I didn't want the money nor the hassle.
3) I made the broker put in writing they would not release funds to the seller until Disney actually transferred the contract.
Disney could stop all of this nonsense but they refuse. I suspect they see it as one more potential negative to the resale process.
Sorry you're dealing with this now and good luck.
