§ 24-7-705 [Expert Testimony Without Prior Disclosure of Basis]

When an expert witness gives their opinion in court, they do not have to start by explaining all the facts or information they used to reach that opinion. They can simply state their conclusion or recommendation first.

However, the other side has the right to question the expert during cross-examination and ask them to explain exactly what facts or data they based their opinion on. The judge can also require the expert to share that background information if they think it is needed.
