Yes, you need evidence of your payments made direct to your creditor to show to the Solicitor (bank statements), if you cannot personally provide proof then get your creditor to confirm to the Solicitor that you have in fact made all payments as ordered by the court.
If you were served with a court summons, take all your evidence and show it to the court that you have not defaulted on their original order. This would leave the court refusing to apply or place the charging order, as long as you can demonstrate that you have kept up all repayments just like the court originally ordered you to make.
