This summary is not the rule. The rule text controls.
If you file a small claims case, or if someone files a counter claim against you, the other side does not have to file a written answer. You will not get a formal response denying what you claimed. Instead, the law automatically treats everything in your claim as if the other side has denied it.
This means you should not expect any paperwork back before your court date. It also means you cannot assume the other side agrees with any part of your claim just because they stayed silent. When you go to court, you will still need to bring your proof and be ready to explain your side, because nothing has been admitted or agreed to ahead of time.
