What does deputyship mean?
Deputyship denotes the office, position, or tenure of a deputy — someone formally empowered to act in place of another. It can describe any situation in which a substitute temporarily holds authority, as when a vice-chairman assumes leadership during an executive's absence. The word also carries a specific technical meaning in English law: under the Mental Capacity Act 2005, a deputyship is a court-ordered arrangement through which a trusted individual manages the property, finances, or welfare of a person who lacks the mental capacity to do so themselves. In this context it is a formal term encountered in applications to the Court of Protection. More broadly, the word connotes delegated rather than original authority — a reminder that power held in deputyship is borrowed, provisional, and exercised on behalf of someone else.
The office, position, or period of service of a deputy; the state of acting on behalf of another person with their delegated authority.
"Her deputyship ended when the governor returned from abroad."
In English law, a formal appointment by the Court of Protection authorising a person to make decisions on behalf of someone lacking mental capacity.
"A solicitor advised them to seek a property and affairs deputyship for their father."
Specifically associated with the Mental Capacity Act 2005 in England and Wales.
Used mainly when referring to multiple separate appointments or periods of office.
"He served two deputyships under different administrations."

Etymology of deputyship
Deputyship derives from 'deputy', which entered English from Anglo-Norman and medieval Latin 'deputatus', the past participle of Latin 'deputare', meaning to allot or assign. The suffix '-ship' forms nouns denoting state, condition, or office. The compound thus literally means 'the state of being deputed'. Its cognates include 'depute' and 'deputize', all tracing back to the same Latin root combining 'de-' with 'putare' (to reckon).
How deputyship is actually used
Chiefly formal or administrative in register. The legal sense is strongly associated with British law under the Mental Capacity Act 2005 and is less familiar to general readers.
