Yes, a Consent Order, like any order, can be varied by reason of change of circumstances, such as retirement or redundancy or one of the psrties winning the Lottery, but if only a short time has elapsed since the order was made your ex is going to bring forward some pretty good reasons.
Sorry, that reply was perhaps ambiguous. I don't know what was in your order for orders for transfer of property. lump sums, etc, can be varied only in very exceptional circumstances, mainly if the order was obtained by fraud or concealement. An order for spousal maintenance can be varied on the grounds of change of circumstances, but
orders relating to capital in general, cannot.
Depends on terms of your order, if u got a Clean Break then you cant change the terms of the order nor the % split even if one of you won lottery... i think in all orders there is the terminology to apply to have its terms implimented, ie if your ex has to pay u X amount of pounds by such and such but doesnt then you would have to apply back to court to get this sorted.
