Rule 520 The party claiming that a person is guilty of crime or wrongdoing has the burden of proof on that issue.

If you accuse someone of a crime or wrongdoing in court, you are responsible for proving it. The other person does not have to prove they are innocent.

This applies in both criminal and civil cases. Whether you are a prosecutor, a lawyer, or a regular person making a claim, the proof falls on you if you are the one making the accusation.
