Dear Sir Paul
Pre-Nuptial Agreements are generally worth considering for someone in your position. They are not binding under English law but if they are set up properly the Court will take a good deal of notice of them.
Before you make a Pre-Nuptial Agreement you will need to give full disclosure of your financial position. I realise this must be a daunting task but if you Email Me I will send you our Financial Disclosure Questionnaire which most clients find very helpful.
With best wishes for the future.
