Washington State Real Estate Practice Exam

An affidavit must be authorized and notarized to be considered valid. This means that it must be signed and verified by a public official, such as a notary public, who acts as a witness to the signing. Option B is incorrect because an affidavit does not necessarily have to be sworn, it just needs to be signed and notarized. Option C is also incorrect because it only requires a witness, but not a notary public. Option D is incorrect because there is no need for an affidavit to be registered, it only needs to be notarized.
