Not saying that triviality is not the best option for you, but you can ask them to calculate out the pension in any way you want, you can reduce or remove the lump sum, have a fully transferrable pension, have a pension for the surviving partner of a percentage of her pension e.g. 50%, she can put in a guarantee so that in the event of her death, the pension could continue to be paid in full for a set number of years. All these options of course will change the amount of pension payable. Whether her pension can be paid as triviality will depend on what other pension provision she has, her provider should ask for details.
