This summary is not the rule. The rule text controls.
If you have a small claims case anywhere in Indiana, these rules are the ones that apply to your case. This includes small claims courts in Marion County, as well as small claims cases handled in other courts across the state. No matter where your case is filed, as long as it qualifies as a small claims case under Indiana law, these same rules will guide how the case moves forward.
The second part just explains how to refer to these rules in writing. If someone needs to point to a specific rule, they can write it as "S.C." followed by the rule number. This is mostly useful for lawyers, judges, or anyone filling out legal paperwork who needs a short way to reference these rules.
