If you change anything, all the beneficiaries must agree,
Okay, humour me here if I sound a tad obtuse, or if I’m missing something that’s glaringly obvious, but if what you state is correct, then if a person who has £240,000 to distribute between his wife and two sons, makes a will leaving each of them £80,000, then a few months prior to his demise decides to change his will to £100,000 to his wife, and £70,000 to each son, he can only do that if his wife and both sons agree?
How would that work if his wife and sons had no knowledge of the wording of the original will?
ETA, as I’m reading this back before hitting “reply to thread”, it slowly dawned that you could mean that it can only be changed if AFTER the will has been read, one of the sons says, “I think that mum should get £100,000, and Blank and I get £70,000 each.”
Then, ONLY if Blank agrees, it could be changed.
That sounds more like what you might have meant, so apparently I did indeed miss something glaringly obvious, I’ll go stand in the corner.
