A more thorough explanation:

Definition: Lex domicilii is a Latin term that refers to the law of the country where a person is domiciled. It is used to determine a person's rights by establishing where, in law, that person is domiciled.

Examples:

• If a person is domiciled in the United States, the lex domicilii would be the laws of the United States.
• John is a citizen of Canada but has been living in Australia for the past five years. His lex domicilii would be the laws of Australia.

The examples illustrate how the lex domicilii is used to determine which country's laws apply to a person. In the first example, since the person is domiciled in the United States, their rights would be determined by the laws of the United States. In the second example, even though John is a Canadian citizen, his lex domicilii would be the laws of Australia because he has been living there for an extended period of time.
