There is no definitive answer to this question as it can vary depending on the jurisdiction in which you are filing your lawsuit. However, some jurisdictions have what is known as a small claim's court where individuals can file lawsuits for relatively small amounts of money. The threshold for how much money you can sue for in small claims court varies from state to state, but is typically around $5,000 or less. So, if you are looking to sue someone for a very small amount of money, your best bet would be to file in small claims court.
