We are not aware of any prohibition against filing a small estate affidavit with a court. However, we agree that such a filing is not required in Illinois. The Illinois Probate Act requires a financial institution to comply with a small estate affidavit that is in substantially the same form outlined in the Act, and it protects financial institutions from liability when relying on a small estate affidavit — regardless of whether the affidavit has been filed with a court.

• Probate Act of 1975, 755 ILCS 5/25-1(d) (“Any person, corporation, or financial institution who acts in good faith reliance on a copy of a document purporting to be a small estate affidavit that is substantially in compliance with subsection (b) of this Section shall be fully protected and released . . . .”)
