A more thorough explanation:

Definition: Lex ligeantiae (leks lij-ee-an-shee-ee) is a Law Latin term that refers to the law of the country to which a person owes national allegiance. Some legal experts believe that this law should be used to decide many of the questions that are typically determined by the lex domicilii.

For example, if a person is a citizen of the United States but is living in Canada, the lex ligeantiae would be the laws of the United States. This means that if this person were to get into legal trouble while in Canada, the laws of the United States would be used to determine their legal rights and responsibilities.

Another example would be if a person is a citizen of France but is living in the United Kingdom. In this case, the lex ligeantiae would be the laws of France. If this person were to get into legal trouble while in the UK, the laws of France would be used to determine their legal rights and responsibilities.

These examples illustrate how the lex ligeantiae is used to determine which country's laws should be applied to a person based on their national allegiance. It is important to note that this can sometimes be different from the laws of the country in which they are currently residing (the lex domicilii).
