Affidavit of Heirship need attorney?

[David Jonsson]

My seller has a will stating she inherited house. She will file that with circuit clerk and bring copy to closing. She does NOT have an affidavit of heirship which the title company needs to determine about any claims or taxes due out of estate. Does she need an attorney to do this or just download an online form and fill it out? I think a third party might need to be involved.. what is cheapest and easiest way for her to do this? She is 94 years old. My attorney told me to be careful about acting as an attorney for her because im not a lawyer obviously. but anyway how do i make sure seller brings this doc to closing? thanks
