My husband and I are in the process of writing our wills. We don't have children and other than some charity bequests we're planning on dividing our assets between our nieces and nephews. At the moment it's easy just to list them but I don't want to end up in a situation where more children have been born but aren't listed in the wills and it causes family arguments or upset.
Is there some sort of clause where we can say "any future children" or does it need names? I'm reluctant to pay to update our wills every time one of our siblings sprogs up.
