We made one in our 40s and I remember the late father in law laughing and asking why we needed to do that. He passed away seven years ago without a will and it was a nightmare sorting everything out for the mother in law. Made an upsetting time even worse. It’s a must do.
Daisy is definitely in the wrong, leaving an option of (a) engaging solicitors unfortunately with associated costs that could fluctuate or (b) sending the lads round to 'have a word' ( and might work for fixed fee )
