How to remove marks on my credit rating

Was just after some advise on some marks I have on my credit rating.
I recently went through a divorce in which I had to go through the courts for a financial settlement.
An order was made that the family home that’s mortgaged in my sole name is to be paid by both parties in which it states how much we both had to pay.
I paid what was stated in the order to the mortgage lender but my ex didn’t pay her share leading the account into arrears.
I had to take her back to court to force the sale of the property due to this. The house is now up for sale but want to know is there any way I can get these marks taken off my credit file as I did exactly what was ordered of me through the courts?
