Being brutally honest the excess deaths in the last year have possibly resulted in there being a bit more 'estate' to hand on: less assets consumed by care home fees, death in service benefit, life insurance policies.
It's easy to be blase about inheritance when it isnt you who is going to miss out on a significant legacy because of the absence of a will or a badly drafted/out of date will.
Many people put will writing into the 'do it tomorrow' category. Many people write wills then forget about them and dont check them every few years to make sure they do reflect their current wishes.
It's easy to see how even quite a simple will can get out of date. DH and I decide to leave our estate to our DCs, Daphne & Paul. Mentally we give ourselves a pat on the back as our wills are now 'done', we are leaving our estate to our children. Time goes by, we have a third child, Bertha.
They all grow to adulthood and independence. DH & I die, the wills come out and our estate is only left to our older two DCs, nothing for Bertha. What we meant to do was leave our estate to be split between our DCs. What we have in fact done is leave one of our DCs shocked and hurt with no legal recourse.
MN will say that if we had wanted to leave anything to Bertha we would have put it in our wills. But in our heads it is clear that we wanted to leave our estate to all our children. We may have forgotten that the wills were written before Bertha was born.
