An adverse credit remortgage is when someone with poor credit still is able to refinance his or her home, but only after agreeing to special security provisions put into the new mortgage agreement.

If someone has had credit problems, but wants to take advantage of the new lower interest rates now available, there are banks and finance companies that will allow that person to refinance to a lower interest rate, but only if the person agrees to special arrangements that give the lender a little extra security in the arrangement, considering the fact that the borrower has perhaps defaulted or failed to pay things on time previously, thus causing the low credit rating.

"Adverse credit remortgage" is a mouthful, but it just means that even if your credit is bad, lenders will refinance to a lower interest rate, if you give some extra promises to compensate for the fact that your past record in paying things off on time hasn't been all that great.
