Thanks for your question.
There's no way that the registered title can be transferred in to your sole name at the Land Registry but to, at the same time, have your wife remain as the legal joint owner - you can't have your cake and eat it in that way.
You and your wife could execute a declaration of trust upon the title being transferred to you sole name in which you state that although you are the legal owner of the property and that the charge is the first call on the property the proceeds of any sale shall be split between you both in specified percentages (eg. 50% each).
This would be enforceable by your wife in the event of a sale and could be registered against the title as a notice so she would know about any sale before it happens, so that she would receive her share - but it is only an interest in the proceeds of sale, it is now "ownership".
This would not prevent her seeking to revise your arrangement by way of a Court Order pursuant to your divorce either.
Sorry it could not be better news.
