1. we are all getting old
2. yes ( or no) it is £3000 for one person in one year
3. every years ( £3000)
so that is £21 000 over seven years
BUT - you can do the little known loop of any amount so long as it is out of income, anddoes not impoverish you.
I am certain Raisin cover this
it is very wise ( necessary I would say) to document this at the time.
Otherwise, do the £21 000 bit and live for seven years
I do not see why if one of you die, the live one says - no I gave it.
