Rule 11-601 Competency to testify in general.

Almost anyone can testify as a witness in court. There's no automatic ban based on things like age, mental condition, or a criminal record. The general rule is that people are allowed to take the stand and give testimony.

The only exceptions are cases where another specific rule says a person cannot testify or limits how they can testify. So while the starting point is that everyone qualifies as a witness, other rules might set up special situations that change this. If you're wondering whether a particular witness can testify, you'd need to check if any of those other rules apply to their situation.
