Filing fees are charges that individuals or businesses must pay when submitting legal documents to a court or government agency. These fees vary depending on the type of filing, such as civil lawsuits, bankruptcy petitions, or business registrations. They help cover the administrative costs of processing the documents. In addition to the initial filing fees, there may be additional costs for services like serving papers or obtaining certified copies of documents. It's important to check the specific fee schedule for the relevant court or agency, as these fees can change and may differ by location.
