A witness is a person who gives testimony under oath. They can testify about something they saw, experienced, or know to be true. Sometimes a witness can provide testimony through a written affidavit, which you can give to the court as evidence. Depending on your case, a witness may be helpful or even necessary.
A witness can:
- Testify about something that you have no other proof of. For example, you do not have a record or receipt of a loan from a friend. Your friend can testify about the loan in court. Another example may be if you paid someone for childcare but do not have a receipt. The childcare provider can be your witness.
- Support your own testimony or story. For example, you had a bruise but did not take a photo of it. A family member who saw the bruise can testify about its size, color, and location. Another example may be a friend who saw the other party drive an expensive car but they say they cannot afford child support.
- Lay a foundation for evidence that you want the court to consider. Your witness can authenticate certain evidence. This means to show that it is what you say it is. To do this, the witness must be familiar with the evidence. For example, a witness can explain that a photo shows what they saw at the time. Or, hospital staff can say that a medical record is a “fair and accurate” record. To learn more, see our “Evidence” guide.
You may also want to use an expert witness. An expert witness is someone who can give a professional opinion, not just facts. One example may be a doctor to give a medical opinion. Experts are mostly used in custody cases.
Keep in mind that you may need to pay the expert witness to testify. This can be expensive. Expert witnesses also require different kinds of notice and rules. If you think you need an expert witness, it may be best to hire a lawyer if you can. Or, you can ask the court if you qualify for a court-appointed lawyer. Do this as early as possible.
Note
Your witness can voluntarily agree to testify. If not, you may need to subpoena the witness. See our guide on “Subpoenas” to learn more.
