That link seems a bit more helpful than the .gov.uk that I linked to.
It say this about your partner being able to inherit your contributions record to top up a pension
"If you die while they are under state pension age, they will lose this right if they remarry or enter into a new civil partnership before they reach state pension age."
And this about a divorced partner
"You may be able to use the national insurance contribution record of your ex-spouse or ex-civil partner to help increase your basic state pension if you are divorced or if you have dissolved your civil partnership.

This won't affect your ex-spouse or ex-partner's basic state pension. If you remarry or form a new civil partnership before you reach state pension age, you lose this right. "

From these I would guess that since you are both already claiming State Pension your pension will not be affected.

But don't take my guess - ring that freephone number and find out.
