Final answer:
The signer of an affidavit can indeed acknowledge their signature in front of a notary public, a process necessary for the affidavit's validity.
Step-by-step explanation:
True: The statement is true. The signer of an affidavit can acknowledge their signature in the presence of the notary public. This process, known as notarization, involves the signer appearing personally before the notary to declare that the signature on the document is theirs and that the document was signed willingly for the purposes stated within the document. The notary public then verifies the identity of the signer, witnesses the acknowledgment of the signature, and stamps or seals the document to complete the notarization process. It is crucial for the validity of the affidavit that this process is carried out correctly.
