A commissioner of deeds is like a special helper who helps people make important legal documents called affidavits. An affidavit is like a promise or a statement that is written down and signed by someone who wants it to be official. Sometimes, when you need to make a promise or a statement, it needs to be made in front of someone important to make it extra official. That's when a commissioner of deeds comes in! They are like a special witness who sees you sign the affidavit and makes sure everything is done correctly. They have been specially trained to do this job and are authorized by the government to help people make these important legal promises. It's kind of like having a special grown-up helper to make sure everything is done correctly when you need to make an important promise or statement!
