Stephanie and thanks Just Answer.
My name is ***** ***** am happy to assist you with your enquiry.
You are indeed correct- "net proceeds" means whatever monies are left over and due to you from the sale. ie after deduction of your Estate Agents, Solicitors fees and any Mortgage that needs to be paid off.
(If the Order had said your ex is entitled to 35% of the GROSS proceeds, this would have equated to 35% of the Sale price).
I hope this clarifies matters , and the Solicitor acting in the Sale will wish to see a copy of the Order, and no doubt will also be able to confirm the above to you.
If I can be of any further assistance, please let me know.
