First the divorce should be granted. Only then things can be exchanged, without divorce being granted why do you want to return things? If returning things will assure you divorce, then go ahead by preparing a list of items you have in hand, and also a list of things which are in her hand which belong to you, make such list, carry such VAT bills if you want to claim ur items which are lying with her, and she should also give original VAT bills to claim items from you, if she fails or you fail,, you and her can forget such items. This can be done on next date.
