V v good point Mrs F
First of all you have to certain you are gonna get all of Mr F's moolah.
But if you are - then you get all the money ( no IHT between spouses )and can give it to Lad 1 and 2.
If you do not survive 7 y they MAY have to pay tax
But remember Mr F has not used his £325k free tax band.
and it may be useful to use it to give the lads tax free bequests in his will
So der dahh it is the usual advice - see a lawyer
IN fact practically the answer is almost certainly no unless the whole of your husband and yours estate exceeds £650 k. Easy in London and difficult in Humberside
But ten out of ten for thinking - what will happen when I die and how can I minimise tax ....
