Common confusion points
Mistaking this for a simple Witness Statement—this form specifically attests to *capacity* (mental ability).
Not knowing who needs to sign: The person making the affidavit and the witnesses.
Assuming one signature is enough; check the specific requirements listed on the form itself.
Filing it without having already applied for probate—it supports the application, but isn't always the first step.
