What service method involves sending documents by mail with proof of service?

• A. Service by Fax
• B. Personal Service
• C. Service by Mail
• D. Electronic Service

Answer: (C)

Sending documents by mail with proof of service is called service by mail. In New York civil practice, this method becomes effective as soon as the papers are mailed to the party’s last known address, not when they are received. To show that this has happened, you typically file a proof of service—an affidavit from the person who mailed the documents stating when and to whom they were mailed, the address, and that proper postage was used. This distinguishes it from other methods: personal service involves handing the papers to the party or their agent, while service by fax or electronic service uses a different delivery method and separate proof requirements.
