I would strongly urge you to discuss this with the attorney that represented you at closing. They can discuss this with the sellers attorney. Also Karla is correct, you should also contact the title company to inquire regarding what monetary damages you are entitled to as a result of this mistake.
Real Estate Agent
Depending on the circumstances, here in New York State the title company, the real estate firm, or an attorney could be responsible for an error on the HUD.
This may or may not be relevant, but just so you know, one function of title insurance is to pay for mistakes that happen connected to a closing. I know of title companies making good--that is, paying real money--on a variety of problems that were not discovered until after the closing.
If the sum of money is large enough, it might well be worth making a few phone calls to see if you can obtain reimbursement fairly easily and quickly. If the sum is very large, a good real estate attorney might be worth bringing on board.
Best of luck to you!
