A more thorough explanation:

A name-and-arms clause is a legal term used in wills or property settlements. It requires the recipient of the property to continue using the testator's or settlor's surname and coat-of-arms. If the recipient fails to do so, the property will pass to another person.

John Smith, a wealthy landowner, includes a name-and-arms clause in his will. He leaves his estate to his son, James Smith, on the condition that James continues to use the family surname and coat-of-arms. If James changes his name or coat-of-arms, the estate will pass to John's brother, William Smith.

Another example is a property settlement where a husband transfers ownership of a house to his wife. The settlement includes a name-and-arms clause, requiring the wife to continue using the husband's surname and coat-of-arms. If she remarries and changes her name or coat-of-arms, the property will pass to the husband's brother.

These examples illustrate how a name-and-arms clause can be used to ensure that a family's name and coat-of-arms are preserved through generations. It is a way to maintain the family's identity and legacy.
