I used a lawyer to write a Will for me sum years ago, giving all the necessary details of what I wanted. He told me it would take at least a week for him to complete.
When I went back to sign I was almost on the point of rearranging his face, but held back.
He had changed many of the details and made himself the beneficiary, hiding that quite cleverly, possibly hoping I wouldn't notice? I tore up the Will into little pieces and threw it into the air and walked out. There was no protest.
