Rule 604: Interpreter | DE Evidence

An interpreter must be qualified and must give an oath or affirmation to make a true translation.

If a court case needs an interpreter, that person must be able to do the job well. They need to show they have the skills to translate accurately between languages.

Before the interpreter starts working, they must make a promise to the court. This promise means they will translate everything honestly and correctly, without changing the meaning of what is said.
