Which of the following is NOT a typical requirement for a valid will?

A valid will typically has several requirements to ensure it is legally enforceable. One of the primary requirements is that it must be in writing, which ensures that there is a tangible document reflecting the testator's intentions. Additionally, the will must be signed by the testator, which signifies their approval and acknowledgment of the document as their last will and testament.

In many jurisdictions, having two witnesses sign the will is also a standard requirement. These witnesses confirm the authenticity of the testator's signature and their mental capacity at the time of signing.

However, while a self-proving affidavit is a useful feature that can speed up the probate process by allowing the will to be admitted to probate without requiring the witnesses to appear in court, it is not a mandatory requirement for a will to be valid. A will can still be valid even if it does not include a self-proving provision. This is why the notion that a will must be self-proving is not a typical requirement for its validity.
