Updated June 17, 2022

A Washington last will and testament is a legal document that allows a “testator,” the creator of the will, to set forth instructions on how they would like their estate to be distributed in the event of their death. Assets and property under the testator’s estate considered for distribution may include businesses, digital assets, real estate, personal property, life insurance policies, among many other important assets/property. Generally, assets are distributed to continue the financial security of the testator’s immediate and extended family; beneficiaries are usually spouses, children, relatives, and friends. However, some testators choose to make charitable donations to educational institutions or even specific research facilities for various personal reasons. After the testator has constructed the will to their satisfaction, it must be signed in the presence of two (2) witnesses — both of whom will also sign the document. Revisions and revocations to the will can be made by a testator of sound mind at any time.
