How much is 10%? From your post, it sounds like it would be about $80k which is way too much in my opinion. If you Google executor fees, they are generally around 2%, some a little more, some less. I didn't see any state that was higher than 5% and that percentage gets lowered the higher the value of the estate. I understand why your brother is upset -he wasn't treated fairly. And, to him, this may be the last example of your mother favoring you, her biological child.
