You do understand I hope that the "I feel so hurt" comment was said with tongue fully in cheek.
I should mention that I am on hiatus from active practice, so it would be more accurate to describe myself as a former estate law lawyer, but I still am fairly fresh.
If you delve into the rules about this estate law stuff, most likely you will find that it is actually very old, and can be unbelievably complex in areas that you wouldn't expect. It also varies a lot depending on which jurisdiction's laws apply. In Canada, where I am, there is a wonderful and weird conglomeration of old English law, modern Canadian law and (to a small extent) law borrowed from other places around the world (our land registry system, for instance, was borrowed from New Zealand and a system respecting ships). Each of our ten provinces and three territories has different laws - twelve of them are quite similar, while the 13th is Quebec, which is rooted in an import from France.
As I said, informed local professional advice is a very good idea.
EDIT: One other point - if you are in a jurisdiction like mine, you need to obtain valuation information
before you apply for Letters Probate, because the application materials require an extensive inventory of what is known to be in the estate, along with accompanying values. In other jurisdictions, as I understand it, the procedure is considerably different. So depending where the OP is, the need for valuation may come earlier, or later.
