Legal Definitions - first name

LSDefine

Simple Definition of first name

The "first name" is the given name of an individual, typically assigned at birth or through legal processes like adoption. It serves as a key identifier and is distinct from a person's surname or family name, forming a fundamental part of their complete legal identity.

Definition of first name

A first name refers to the primary personal name given to an individual, typically at birth or adoption, which precedes their family name (surname) and serves as a key identifier.

Here are some examples illustrating the application of a first name:

  • Example 1: Official Identification Documents

    When applying for a driver's license, Sarah Smith fills out the application form. In the section labeled "First Name," she writes Sarah, while her last name, Smith, goes in the "Last Name" field.

    This illustrates how "Sarah" functions as her first name, distinguishing her from other individuals who might share the surname "Smith" and serving as a crucial part of her legal identity on official documents.

  • Example 2: Legal Proceedings

    During a court hearing, the judge addresses a witness by saying, "Mr. Johnson, please state your full name for the record." The witness responds, "My full name is David Johnson."

    This demonstrates that "David" is the witness's first name, used in a formal legal setting to establish his identity clearly and ensure proper record-keeping of who is testifying.

  • Example 3: Contractual Agreements

    In a lease agreement between a landlord and a tenant, the document specifies the parties as "Landlord: ABC Properties, Inc." and "Tenant: Maria Rodriguez." Both parties sign the agreement, with Maria signing as "Maria Rodriguez."

    This shows "Maria" as the first name of the tenant, clearly identifying her as the individual entering into the legal contract and distinguishing her from others who might share the "Rodriguez" surname.
