Which of the following is NOT a characteristic of a valid will?

A valid will is typically characterized by several key components, and one of those aspects is that it does not necessarily need to be registered with a government agency to be considered valid. The primary requirements for a will to be valid include that it must be in writing, it must be witnessed (usually by at least two individuals), and it must clearly express the testator's intent regarding the distribution of their assets upon their death.

While many jurisdictions may offer or require registration for administrative purposes, such as locating the will after the testator's death, registration is not a foundational requirement for the will's validity itself. Thus, the requirement for registration is what makes this option not a characteristic of a valid will.

In contrast, the other characteristics are fundamental to ensuring that the will accurately reflects the wishes of the testator and adheres to legal standards for enforceability. Writing ensures clarity and permanence, witnessing helps prevent fraud and proves the authenticity of the will, and expressing intent demonstrates the testator's wishes, making it clear how their estate should be managed after their passing.
