Hello and thanks for using Just Answer.
My name is ***** ***** am happy to assist you with your enquiry.
Your ex wife's Solicitor will need to provide an Undertaking to the Buyers Solicitors that all charges registered against the property will be cleared upon completion.
Therefore, there is no way that the Sale can complete without her Solicitor contacting you. If you do not wish to instruct your own Solicitor to deal with the discharge of your Charge, your ex's Solicitor will write to you and will ask that you sign the appropriate Land Registry form, releasing your Charge, in return for him sending to you the sum that you are due.
As i have said, you could instruct your own Solicitor to oversee this, but there is no reason why you can't do it yourself- just make sure that your ex's Solicitor provides a full breakdown of the Sale price and the amount due to you as well as an assurance that he will pay you your due amount on completion of the Sale.
I hope this helps you and sets out the legal position.
Can I assist you any further?
