Hi, could anyone with legal knowledge offer some advice on this? My son, 17, has been left a share of my mum's estate. The will says nothing about his age and I'm the executor along with another person who isn't a beneficiary. I believe this means a trust is automatically established until he is 18, but I'd much rather have his share in trust til he's 21 or 25. Can the executors or the beneficiaries vary the will to do this, with his agreement (or without it?)
