and the third cannot remember anything about the decedent or the execution of the will and refuses to sign an oath. The will was executed over 32 years ago. I am the sole living heir of the deceased as well as the sole beneficiary under the will so I am considering filing the summary administration as intestate. However, there is a valid will and I would prefer to file as testate with a copy of the will and an affidavit from me as a nominated personal representative under the will stating that the will is the true last will of the decedent and explaining the situation of the witnesses. Can I do this?
