For a will to be valid according to the provided criteria, what must occur?

A will must meet certain criteria to be considered valid, which can vary by jurisdiction. In many places, the requirements may include being in writing, signed by the testator, and sometimes witnessed. By selecting the answer indicating that both notarization and being in printed form are necessary, it implies that each of these conditions has to be met for the will’s validity.

However, it's important to note that whether a will must be notarized or in printed form or witnessed by a specific number of individuals isn't universally applicable; different jurisdictions have different rules. Therefore, stating that both conditions must be met suggests that the answer encompasses the full breadth of what might be considered necessary for a valid will across various scenarios or requirements. In general legal principles, ensuring that the will is properly executed with the required formalities established in law will lead to its validity. This understanding is critical for anyone practicing law or involved in estate planning.
