Rysaffe Planning

I have been asked to review Wills (executed 28th May 2014) for a married couple.
They have an estate comprising of a main residence worth £800k and investments via St James’ Place worth £1.2m. No liabilities. 2 adult children and 3 grandchildren.
Thier current wills give everything to each other in the first instance and then:
12.5% to each child
15% to 5 trusts established on consecutive days dated 24th to 28th March 2014.

Can anyone advise please if these Wills are still OK or should they be scrapped? If they are no good can you recommend what should be done instead please?
