Most people write their wills with the intention of benefiting their nearest and dearest, a poorly written clause may have the opposite effect from that intended.
what makes you think the average joe offspring of a testator is going to be better placed at spotting an inadvertent unfairness than a solicitor?
Does having a will make a person more vulnerable to theft?
Can you really not see that the answer is yes? anyone who wanted to make a specific bequest would have to publically record what that bequest was. Jewellery, art, furniture, cars etc - all listed nicely for a burglar or conman to peruse. And what about those who set up trust funds for their beneficiaries? That’s a pretty good advertisement that you have assets that might be worth stealing.
unless the bequest is of great significance (eg 'I leave the Rembrandt to George and the Monet to Mildred') then will it make the testator more vulnerable?
If people only bothered stealing when the goods were as valuable as rembrandts there would be virtually no burglary in the U.K., and yet house breaking is a common crime. How do you figure that one out?
Having the will accessible before it comes into use would give potential executors or beneficiaries the chance to discuss provisions with the testator.
What if testators want to include unfair clauses? What it they prefer one child to another, or want to leave everything to a donkey sanctuary? It’s their right to do so. Should they be harangued for the remainder of their lives because of it?
Or what if they split their estate absolutely equally between all descendants but one entitled little narcissist things they deserve a bigger share? Are you really saying you want to actively encourage potential beneficiaries to argue with old and vulnerable people about who most deserves to benefit from their death?
You’re acting as though there’s some golden rule whereby all testators want to split everything totally equally between their descendants, only they keep falling prey to accidental mishaps in the wording. The reality is so much more complicated than that. Not all families are happy. Not all people are good.
Old people deserve better than to be considered nothing more than a vehicle for making their descendants richer. They deserve to be protected from manipulation and coercion from interested parties. They deserve to have the freedom to decide what happens to their estate, and nobody has the right to try and persuade them out of the decisions they make.
