The hard part is over.
I'm matching you with one of our specialists who will be calling you in the next few minutes.
You might want to keep her last income tax paperwork. Last bank statement. Maybe the Probate paperwork a little longer. Her funeral papers. But I think you will be safe shredding it all. The IRS only goes back five years.
My parents kept copies of their income taxes since day one when the earth was discovered, so I went amuck with shredding keeping just the past few years. Chances of my parent's income taxes being audited is like less than 1%. But I did save the last couple of years.
I did keep all the Deeds to houses long since sold, and "paid" mortgage notes. I will need to check around and see if I really do need to keep these items.
My parents and grandparent's birth certificates, marriage license, etc. I have in the family tree binder.
