Re:

im glad you were able to put this stressful time to rest. I believe that there is no reason to hide the fact of our concerns, i would ask that harry and the girls explicitly acknowledge the fact that you are not leaving them any money or their children, they will not bring any action against valeria, for any reason whatsoever.

Worth doing, no doubt. But I think it would be better to let today's arrangement to be sealed and delivered before making this demand.
