Illinois Self-Proving Affidavit Form

The Illinois self-proving affidavit is an attachment for a last will and testament that proves the authenticity of the will to the probate court. Beneficiaries of the last will and testament will find the self-proving affidavit advantageous as it expedites the legal proceedings following the death of the testator (the creator of the will). Due to the application of a self-proving affidavit, the testator’s witnesses will not be required to appear in court to attest to the validity of the document thus hastening the probate process. The testator must sign the self-proving affidavit before two (2) witnesses. While not required by law, it is recommended that a notary public also be present when the affidavit is signed.
