Putting a notice in The Gazette (previously The London Gazette) giving claimants against a deceased’s estate at least two months to advise executors of their claim is advisable but it is not required by law.
That was the gist of what I picked up - ie it's not compulsory to do that notice, but if someone had "popped out of the woodwork" that none of us knew about = it was my understanding that "someone" could demand any monies they found to be due to them to come from the executors. I wouldnt have been bothered personally - from what I remember - as a beneficiary, but not an executor - as the money would come from the executors share. My own share would have been safe - if I'd already received it.
