Legal name

Legal name is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Legal name rather than just read about it. In short: A legal name or wallet name is the name that identifies a person for legal, administrative and other official purposes. A person's legal birth name generally is the name of the person that was given for the purpose of registration of the birth and which then appears on a birth certificate (see birth name), but may change subsequently.

Key takeaways

  • Legal name belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Legal name to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Legal name from memory before moving on to harder problems.

Reference excerpt

A legal name or wallet name is the name that identifies a person for legal, administrative and other official purposes. A person's legal birth name generally is the name of the person that was given for the purpose of registration of the birth and which then appears on a birth certificate (see birth name), but may change subsequently. Most jurisdictions require the use of a legal name for all legal and administrative purposes, and some jurisdictions permit or require a name change to be recorded at marriage. The legal name may need to be used on various government issued documents (e.g., a court order). The term is also used when an individual changes their name, typically after reaching a certain legal age (usually eighteen or over, though it can be as low as fourteen in several European nations). A person's legal name typically is the same as their personal name, comprising a given name and a surname. The order varies according to culture and country. There are also country-by-country differences on changes of legal names by marriage. (See married name.) Most countries require by law the registration of a name for newborn children, and some can refuse registration of "undesirable" names.

Name change Some people legally change their name to be different from their birth name. Reasons for doing so include:

Marriage, which usually involves adopting their spouse's surname. Some couples choose to blend their names together or choose a new surname entirely. Adoption, where the child's surname is changed to match that of their adoptive family. Transgender people adopting a name that aligns with their gender identity. The usage of their previous name is called deadnaming. Dislike of birth name. To remove associations with a slave name imposed on their ancestors. To reclaim a traditional name. To signify a religious conversion or entrance in some clerical or religious orders. A new identity resulting from witness protection.

Jurisdiction by country

Canada

Quebec The Civil Code of Quebec states that "Every person exercises his civil rights under the name assigned to him and stated in his act of birth," and spouses retain their legal names upon marriage. However, a woman married prior to April 2, 1981 is entitled to use her spouse's name in the exercise of her civil rights, provided that they were doing so at that date. A person's legal name can be changed, upon registration, only under prescribed conditions, and only where the person has been domiciled in Quebec for at least one year.

Germany In Germany, names are regulated to a large extent. Apart from possibly adopting the partner's name upon marriage, German citizens may only change their name for a recognised important reason. Among other reasons, a change of names is permitted when the name can give rise to confusion, ridicule, unusual orthographic difficulties, or stigmatization. In certain situations, children's last names may also be changed to their natural, foster or adoptive parent's last name. Transgender people may change their first names. Foreign names in writing systems that are not based on Latin are transliterated according to rules which may conflict with the system of transcribing or transliterating names that is used in the country of origin. Former titles of nobility became integrated into the last names in 1919 but continue to be adapted according to gender and other circumstances.

United Kingdom In the UK, businesses that trade under names other than those of the owner or a corporate entity must display the name of owner and an address at which documents may be served, or the name and registered number of the corporate body and its registered address. The requirements apply to sole traders and partnerships, but there are special provisions for large partnerships where listing all partners would be onerous. The information must be shown on any trading premises where the public have access to trade and in documents such as order forms, receipts and, as of January 2007, corporate websites (to be extended later in 2007 to sole trader websites).

England and Wales In strict English law, if there is such a thing as a "legal " surname, it is easily changed. In the words of A dictionary of American and English law, "Any one may take on himself whatever surname or as many surnames as he pleases, without statutory licence". This does not always seem to have applied to names given in baptism. As noted by Sir Edward Coke in Institutes of the Lawes of England, "a man may have divers names at divers times, but not divers Christian names." But in modern practice all names are freely changeable. Changes of name are usually effected through deed poll, optionally enrolled either at the High Court of Justice or at the College of Arms, with a notice recorded in The London Gazette. Changes may also be made by means of a royal licence obtained through the College of Arms, with similar notice. These enrolment, licence and notice procedures are useful for having the new name appear in official documents; these procedures are therefore less likely to be useful for trans people or victims of abuse.

Scotland Scots law allows anyone who wishes to do so to change their forename(s) or surname and such changes may be recorded in the official register held by the National Records of Scotland. Technically the Registrar General makes a correction to the entry. A correction can be recorded where a birth has been registered in Scotland, or where a person is the subject in Scotland of an entry in the Adopted Children Register, the Parental Order Register or the Gender Recognition Register. The above formalities are not necessary where a spouse/partner assumes the other spouse/partner's surname upon marriage or civil partnership, or reverts to their original name upon separation, divorce or dissolution of the civil partnership. Only one change of name is allowed in the register where a person has not yet reached the age of 16, and afterwards only one change of forename and three changes of surname may be granted during a person's lifetime, provided that at least five years have passed between changes of surname. Name changes may also be recorded where:

Worked examples

Example 1 — a first encounter with Legal name

Start with the simplest possible case. Write down what Legal name claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Legal name before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Legal name ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Legal name

In research
Legal name appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Legal name in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Legal name is common in secondary-school and first-year university syllabi. It links to neighbouring topics Human names, Names, so understanding it makes those chapters shorter.
In everyday life
Look for Legal name outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
