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.
Under U.S. law, a conservatorship results from the appointment of a guardian or a protector by a judge to manage the personal or financial affairs of another person who is incapable of fully managing their own affairs due to age or physical or mental limitations. A person under conservatorship is a "conservatee", a term that can refer to an adult. A person under guardianship is a "ward", a term that can also refer to a minor child. Conservatorship may also apply to corporations and organizations.
A power of attorney (POA) or letter of attorney is a written authorization to represent or act on another's behalf in private affairs, business, or some other legal matter.

In law, receivership is a situation in which an institution or enterprise is held by a receiver – a person "placed in the custodial responsibility for the property of others, including tangible and intangible assets and rights" – especially in cases where a company cannot meet its financial obligations and is said to be insolvent. The receivership remedy is an equitable remedy that emerged in the English chancery courts, where receivers were appointed to protect real property. Receiverships are also a remedy of last resort in litigation involving the conduct of executive agencies that fail to comply with constitutional or statutory obligations to populations that rely on those agencies for their basic human rights.

The Lanterman–Petris–Short (LPS) Act regulates involuntary civil commitment to a mental health institution in the state of California. The act set the precedent for modern mental health commitment procedures in the United States. The bipartisan bill was co-authored by California State Assemblyman Frank D. Lanterman (R) and California State Senators Nicholas C. Petris (D) and Alan Short (D), and signed into law in 1967 by Governor Ronald Reagan. The Act went into full effect on July 1, 1972. It cited seven articles of intent:
A legal guardian is a person who has been appointed by a court or otherwise has the legal authority to make decisions relevant to the personal and property interests of another person who is deemed incompetent, called a ward. For example, a legal guardian might be granted the authority to make decisions regarding a ward's housing or medical care or manage the ward's finances. Guardianship is most appropriate when an alleged ward is functionally incapacitated, meaning they have a lagging skill critical to performing certain tasks, such as making important life decisions. Guardianship intends to serve as a safeguard to protect the ward.
The Mental Health Act 1983 is an Act of the Parliament of the United Kingdom. It covers the reception, care and treatment of mentally disordered people, the management of their property and other related matters, forming part of the mental health law for the people in England and Wales. In particular, it provides the legislation by which people diagnosed with a mental disorder can be detained in a hospital or police custody and have their disorder assessed or treated against their wishes, informally known as "sectioning". Its use is reviewed and regulated by the Care Quality Commission. The Act was significantly amended by the Mental Health Act 2007. A white paper proposing changes to the act was published in 2021 following an independent review of the act by Simon Wessely. It was confirmed on 17 July 2024 that a new mental health act would be legislated for in the forthcoming session of Parliament.
In United States and Canadian law, competence concerns the mental capacity of an individual to participate in legal proceedings or transactions, and the mental condition a person must have to be responsible for his or her decisions or acts. Competence is an attribute that is decision-specific. Depending on various factors which typically revolve around mental function integrity, an individual may or may not be competent to make a particular medical decision, a particular contractual agreement, to execute an effective deed to real property, or to execute a will having certain terms.

An enduring power of attorney (EPA) under English law is a legal authorisation to act on someone else's behalf in legal and financial matters which can continue in force after the person granting it loses mental capacity, and so can be used to manage the affairs of people who have lost the ability to deal with their own affairs, without the need to apply to the Court of Protection.
Lasting powers of attorney (LPAs) in English law were created under the Mental Capacity Act 2005, and came into effect on 1 October 2007. The LPA replaced the former enduring powers of attorney (EPA) which were narrower in scope. Their purpose is to meet the needs of those who can see a time when they will lack capacity to look after their own affairs. There are two types of LPA: health and welfare, and property and financial affairs; either or both may be created. The LPA allows them to make appropriate arrangements for family members or trusted friends to be authorised to make decisions on their behalf. The LPA is created and registered with the Office of the Public Guardian (OPG), an executive agency of the Ministry of Justice of the United Kingdom.

In the law of England and Wales, best interest decisions are decisions made on behalf of people who do not have mental capacity to make them for themselves at the time the decision needs to be taken. Someone who has the capacity to make a decision is said to be "capacitous". Since 2007, there has been a dedicated court with jurisdiction over mental capacity: the Court of Protection, although it mostly deals with adults. Most applications to make decisions on behalf of a child are still dealt with by the Family Court.
