Removing charging order against my property

A private individual obtained a County Court default judgment against me in 1998 then filed a charging order absolute against my property in early 1999. The alleged debt owed was paid off in July 2007 but the individual never removed the charging order absolute against my property. The County Court where the default judgment was entered is no longer in existence but I sent an application for certificate of satisfaction to the County Court I believe is relevant to my matter. The Court responded nbut said since the claim is more than 6 years old and the judgment was registered in 1998, and given that there was no current action on the matter after six years of the judgment being registered, the judgment and claim details have been removed from their records and are unable to assist with the enquiry. Notwithstanding that the subject debt was fully settled in July 2007, enforcement of the judgment may be subject to the 12-year limitation period under the Limitation Act 1980, from what I understand.

I have evidence of payment of the settlement sum in July 2007, but I do not [yet] have an order to discharge the charging order from the County Court. Do I need such an order to apply to the Land Registry to have the charge discharged or can I apply to the Land Registry to have the charge discharged based on the evidence of payment of the settlement sum in July 2007? Thank you.
