A Request for Admission is a written request asking another party to admit or deny the truth of specific facts about the case. For example, "admit that this is your credit card" or "admit you owe $4516.23 to the Plaintiff". If you admitted those 2 things, the Creditor would probably win the case easily. Make sure not to admit something just because it might be correct.
You will need to admit or deny each of the statements in the Request, unless you have a legal reason not to do so. If you have such a reason, you will need to object in writing and explain why you do not believe you should not have to (or cannot) admit or deny that statement.
If you admit a statement, it is considered true for all purposes in the case, and an admission can be used against you at trial. If you deny a statement that is partially true, you should explain what parts of the statement are true and what parts you are denying.
If you are served with Requests for Admission, it is important that you respond in writing within the 30 day time frame. If you do not respond within 30 days, the other side can file a motion asking the court to treat ithe facts stated in all of the requests as true .
In many cases, those admissions can result in you losing your case. You should not simply deny everything either. If you do not admit a statement, the other side may later prove it is true. If that happens the other side may ask the court to hold you responsible for its expenses (including attorneys fees). The court may grant the request because the other side was forced to prove the statement was true when you could have just admitted the fact.
You should review Rule 36 and Rule 37(c) of the South Carolina Rules of Civil Procedure for more information about Requests for Admissions.
