What is required for a testator’s deed to be executed?

The correct answer highlights that for a testator's deed to be executed, there must be an appointment by a court. This aligns with the principles of probate law, where the court often oversees the process of executing a will and ensuring that the wishes of the testator are honored. The appointment by a court can provide official authorization to execute the deed, safeguarding that the property is transferred in accordance with the decedent's wishes as expressed in their will.

While other aspects such as a valid will are important in the overall context, they do not solely determine the execution of the deed. Similarly, notarization, while potentially needed in many real estate transactions to provide authenticity and legality to documents, is not a mandatory requirement for the execution of a testator's deed itself. Thus, the court's involvement becomes crucial in validating the execution process and ensuring compliance with legal standards as it pertains to a person's estate after their passing.
