Testator in the context of "Will (law)"

Inheritance is the practice of receiving private property, titles, debts, entitlements, privileges, rights, and obligations upon the death of an individual. The rules of inheritance differ among societies and have changed over time. In legal terms, succession refers to the process by which a deceased person’s rights and property are transferred to their heirs, while inheritance refers to the actual property or assets that those heirs receive.

Succession may occur either under the generally applicable statutory rules, referred to as intestate succession, or in accordance with the provisions set forth in a valid will. The rules for a testator to devise and bequeath private property and/or debts via will, often must be attested by a notary or by other lawful means.

A lineal or direct descendant, in legal usage, is a blood relative in a person's direct line of descent – the children, grandchildren, great-grandchildren, etc. In a legal procedure sense, lineal descent refers to the acquisition of estate by inheritance by parent from grandparent and by child from parent, whereas collateral descent refers to the acquisition of estate or real property by inheritance by sibling from sibling, and cousin from cousin.

Adopted children, for whom adoption statutes create the same rights of heirship as children of the body, come within the meaning of the term "lineal descendants," as used in a statute providing for the non-lapse of a devise where the devisee predeceases the testator but leaves lineal descendants.

Trustee (or the holding of a trusteeship) is a legal term which, in its broadest sense, refers to anyone in a position of trust and so can refer to any individual who holds property, authority, or a position of trust or responsibility for the benefit of another. A trustee can also be a person who is allowed to do certain tasks but not able to gain income. Although in the strictest sense of the term a trustee is the holder of property on behalf of a beneficiary, the more expansive sense encompasses persons who serve, for example, on the board of trustees of an institution that operates for a charity, for the benefit of the general public, or a person in the local government.

A trust can be set up either to benefit particular persons or for any charitable purposes (but not generally for non-charitable purposes): typical examples are a will trust for the testator's children and family, a pension trust (to confer benefits on employees and their families) and a charitable trust. In all cases, the trustee may be a person or company, regardless of whether they are a prospective beneficiary.

The public trustee is an office established pursuant to national (and, if applicable, state or territory) statute, to act as a trustee, usually when a sum is required to be deposited as security by legislation, if courts remove another trustee, or for estates if either no executor is named by will or the testator elects to name the public trustee.

In common law jurisdictions, probate is the judicial process whereby a will is "proved" in a court of law and accepted as a valid public document that is the true last testament of the deceased; or whereby, in the absence of a legal will, the estate is settled according to the laws of intestacy that apply in the jurisdiction where the deceased resided at the time of their death.

The granting of probate is the first step in the legal process of administering the estate of a deceased person, resolving all claims and distributing the deceased person's property under a will. A probate court decides the legal validity of a testator's (deceased person's) will and grants its approval, also known as granting probate, to the executor. The probated will then becomes a legal instrument that may be enforced by the executor in the law courts if necessary. A probate also officially appoints the executor (or personal representative), generally named in the will, as having legal power to dispose of the testator's assets in the manner specified in the testator's will. However, through the probate process, a will may be contested.

The insanity defense, also known as the mental disorder defense, is an affirmative defense by excuse in a criminal case, arguing that the defendant is not responsible for their actions due to a psychiatric disease at the time of the criminal act. This is contrasted with an excuse of provocation, in which the defendant is responsible, but the responsibility is lessened due to a temporary mental state. It is also contrasted with the justification of self defense or with the mitigation of imperfect self-defense. The insanity defense is also contrasted with a finding that a defendant cannot stand trial in a criminal case because a mental disease prevents them from effectively assisting counsel, from a civil finding in trusts and estates where a will is nullified because it was made when a mental disorder prevented a testator from recognizing the natural objects of their bounty, and from involuntary civil commitment to a mental institution, when anyone is found to be gravely disabled or to be a danger to themself or to others.

Legal definitions of insanity or mental disorder are varied, and include the M'Naghten Rule, the Durham rule, the 1953 British Royal Commission on Capital Punishment report, the ALI rule (American Legal Institute Model Penal Code rule), and other provisions, often relating to a lack of mens rea ("guilty mind"). In the criminal laws of Australia and Canada, statutory legislation enshrines the M'Naghten Rules, with the terms "defense of mental disorder", "defense of mental illness", or "not criminally responsible by reason of mental disorder" employed. Being incapable of distinguishing right from wrong is one basis for being found to be legally insane as a criminal defense. It originated in the M'Naghten Rule, and has been reinterpreted and modernized through more recent cases, such as People v. Serravo.
