What term describes someone who has created a valid will?

The term that describes someone who has created a valid will is "Testator." This is the legal designation for an individual who makes a will, outlining how their assets and estate should be distributed after their death. The will reflects the testator's intentions and provides direction for handling their estate.

In the context of estate planning, a testator plays a crucial role because they are the ones who decide who will inherit their property, thereby ensuring that their wishes are honored. Other terms listed, while related to the process of will-making, have different meanings: a beneficiary is the person or entity that receives assets from the testator's will, an executor is the individual appointed to carry out the instructions of the will, and "testate" refers to a status where an individual has died leaving a valid will. Understanding these distinctions helps clarify the roles involved in the management and distribution of an estate.
