In a hearing the plaintiff has reason to believe that the defendant may have some type of pseudonym or sometimes use a variations of his name (like going by his middle name and leaving out the first).
What questions can the plaintiff put to the defendant to find the full enumeration of all of his names? I don't even know what some types of names are called, like "Catholic Confirmation Name".
Must the defendant answer, or could a judge decide if this is relevant? It could make a difference to evidence, for example if a letter was directed to "Joe Blow" but the defendants legal name is "Jim Joe" but they are one in the same person.
