A law clerk is a helper for a judge or a lawyer. Just like how you might help your mom or dad with a task, a law clerk helps the judge or lawyer with things like reading lots of documents and making sure they are important for the case. The law clerk also helps the judge or lawyer understand the laws and rules that apply to the case. This helps the judge or lawyer make good decisions about what is fair and right. So, a law clerk is like a special helper who works with the judge or lawyer to make sure everything is done correctly for a case.
