Is it this bit (re my homeless children) you mean on the link:
"Trusts for bereaved minors
A bereaved minor is a person under 18 who has lost at least one parent or step-parent. Where a trust is set up for a bereaved minor, there are no Inheritance Tax charges if:
the assets in the trust are set aside just for bereaved minor
they become fully entitled to the assets by the age of 18
A trust for a bereaved young person can also be set up as an 18 to 25 trust - the 10-yearly charges don’t apply. However, the main differences are:
the beneficiary must become fully entitled to the assets in the trust by the age of 25
when the beneficiary is aged between 18 and 25, Inheritance Tax exit charges may apply".
That seems to imply if I exclude the older 3 children from their inheritance entirely then the younger would receive the house in trust and no IHT
(probably unlikely I will die in the next 2 years before they turn 18 actually; but interesting all the same. I knew about the 10 year rules. I cancelled £2.5m of life insurance which was in trust for all the children about a year ago, as decided I was unlikely to die before they left university -my risk, my choice).
On "voluntary" - okay so this house may be worth £1.9m (no other assets). If I die when I'm around 85 ish then it could indeed have been sold before then and divided between the children free of IHT or I pay a commercial rent to the children for it and still live in it but have given it away to them when I turn about 75 ish.
The one thing the state cannot take away from my children is their education. the £1m or whatever I will have paid on that can never be stolen from them by Big State.
