Testamentary succession refers to the process by which a person's assets and property are distributed after their death according to their last will and testament. This legal document outlines the deceased's wishes regarding how their estate should be divided among beneficiaries, which can include family members, friends, or charitable organizations. In order for testamentary succession to occur, the will must be validated through a legal process called probate. During probate, the court ensures that the will is authentic and that the deceased's wishes are honored. If no valid will exists, the estate is distributed according to intestate succession laws, which vary by jurisdiction.
