As an hier am I suppose to be contacted about the probate

Four years ago my dad passed away he left my mom as executor if my mom was unable or did not want the responsibility
it would go to me. I never saw or was told about the will. I was not even advised about the probate hearing. Since then my brother has taken over every thing supposedly he is now executor. I thought in order to get dual power of attorney we had to appear a judge..Just recently my mom passed
my brother wanted us three siblings to share the difference in my moms funeral. I dont agree because my dad left ample money and my mom is still recieving income from a piece of property he sold. do I have the right to be contacted of the probate hearing my brother said he didnt have to. - Is this your question?
