Hi Tracey
It would seem that both you and your ex jointly took out the mortgage on the house in Tipp. And it appears that the house sold for less than the amount outstanding on the mortgage, €94,251 less, if I an interpreted your post correctly.
The news here isn't good. This is going to continue to appear on your credit report. To create a situation whereby it stops appearing on your credit report your ex needs to pay the outstanding €94,251, or see if the lender will agree to close the account in exchange for a smaller amount.
Even after closure, the loan account will still appear on your credit report for 5 years, and then it will drop off and not be seen.
