DH is seriously ill, probably wouldn't be considered to have capacity to change his will now.
We have mirror wills making each other plus our eldest DS as executors signed a year ago.
Ds2 is now 18 and we had drawn up new wills to include him as executor. Nothing else has changed.
It doesn't really matter for DH's will. Provided nothing happens to me before he dies (soon) there will still be two of us to deal with his will and DS2 will understand why it was done this way.
I'm less comfortable with the idea of DS1 being the sole executor for me, to the exclusion of DS2. Not because I have any concerns but it just doesn't seem right.
So, if I sign my half of the new mirror will to add DS2, will that have any impact on DH's current will?
Or, can I sign it after DH's death even though it names DH (plus DS1 & DS2) as executor?
Or, can I just do an addendum to add a new executor after the death of one named?
