Legal DNA Testing: This type of DNA test is done in a special way so that the results can be used in court. When the DNA is collected, special rules are followed to make sure everything is done correctly and the results are trusted.

The results of legal DNA tests are admissible in court and can be used for legal purposes such as establishing paternity, child support, immigration, or changing a birth certificate.

Non-Legal DNA Testing also known as 'Peace of Mind' Testing: This type of DNA test is done just for fun or to learn something interesting, like finding out if someone is related to you. It's not done with special rules, so you can't use the results in court or for official purposes.

The results from non-legal tests are not admissible in legal proceedings due to the less formal handling and verification process.
