i agree with all the comments in the thread above of about having a will, having it up to date (ours were 30 years old) and having it prepared by specialist solicitor .
I've now been in hospital 7 out of the last 9 weeks, and while we did have wills we had them looked at to bring them into the 21st century.
We have now rewritten the wills - beneficiaries haven't changed but we have set up testamentary trusts to make sure that our children get the money and that the money is protected from any future relationship failure that our children might have.
We have also set up all the necessary powers of attorney for both Mrs C and I.
Cost will be about $4k all up but everything is now locked down and correct legally.
I have given the family a spreadsheet with all my accounts, their logons and passwords .
Last and probably least, I've transferred 600k of QFF points (max allowed per year) to my sons. This still leaves me with over a million points.
I'm still trying to decide what to do with ~700k Amex Ascent points and 300k KF points .
I'm still hoping I can get to use them but will have a plan B to move them somwhere else (VA? to me then to family by transfer?) .
@JohnK, plan now, you don't know what's going to happen tomorrow - I'm shocked at the mess I would have left my family if I'd died in the last 6 weeks.
