Generally, any request to admit that is true should be admitted, or a valid legal objection should be raised. If a matter is denied, and later proven at trial to be true, the party that denied the fact, in bad faith, likely will be required to pay the cost of the party that was unnecessarily put to the task of proven that fact. This answer is based on GA law. If you have to ask such a basic question, you have no business representing yourself. Get a lawyer. Litigation is not for laymen.
