Affidavit of Subscribing Witness (Self-Proving)
A pre-prepared witness affidavit attached to a self-proving will. If the will includes this, the witness may not need to appear in court.
Choose your path
Self-proving affidavits have specific requirements.
This form must match exactly what's in the will. If the affidavit doesn't align with the will's execution details, the court may still require the witness to appear in person.
When do you need this form?
The will has a self-proving affidavit and you need to submit it with the probate petition.
