Updated June 01, 2022

A Connecticut self-proving affidavit can be used to confirm the validity of an individual’s last will and testament. The affidavit proves to the probate court that the will was signed legally and that it was created as the free act and deed of the testator (creator of the will). According to State law, a self-proving affidavit can be requested by the testator or, if the testator is deceased, by the executor of the testator’s estate. However, to make the will self-proving, it will be the duty of one (1) or more of the attesting witnesses to appear before a notary public and sign the affidavit. There is no legal requirement for the testator or executor to be present when making the affidavit.


  • Statute§ 45a-285
  • Signing Requirements– One (1) or more witnesses and a notary public.
