If you are unable to pay your mortgage, then eventually your lender will repossess and sell your property to realise its value. If you have had your property repossessed then you may find that, once the property has been sold, you may still owe money to your lender or mortgage indemnity insurer.
Once you are issued with your outstanding balance, you can ask for it to be written off, but your lender probably won’t agree to this.
Your lender should offer you a repayment plan to clear the remaining balance.
