Wills and how they work

[Kit]

As my orders as being delivered I have some questions about how wills work. I have never been involved in the probate of a will.

1. One will left 3/5s to the executor and 1/5 to each of her 2 brothers. If she felt this was unfair could she have split the estate 3 ways? Or does she have to do what the will says and if she felt it was unfair even up the money after disposal? I know she could not have not given her brothers their full share.

2. I received an administration today. There was a will, executors were the 2 sons. It said the executors declined probate and her husband did an administration. I didn't receive a copy of any of the papers but how can you decline to probate a will, if there is one? Or if the sons didn't want to be executor, why didn't the husband probate the will?
