My estate is fairly straightforward - one marriage etc, no limited company, but I do have young children and when we sat down with a will solicitor it really made us think about the various scenarios that could happen. We did one and I still feel relieved I've got something in writing and appointed executors from my wifes and my side of the family.
I'm an executor in my cousins estate and it's been a nightmare (16 months and counting) trying to unravel everything.
