What method is used for mailing service of a complaint and summons?

When it comes to the mailing service of a complaint and summons, the correct method is using Certified or Signature Confirmation Mail. This approach provides a means of ensuring that the documents are delivered securely and that there is verifiable proof of receipt by the recipient.

Using Certified Mail, the sender receives a receipt that serves as evidence that the mail has been sent. Additionally, the recipient must sign for the delivery, providing an extra layer of security and accountability. This is crucial in legal matters where the delivery of documents such as complaints and summonses must be documented to establish that the recipient has been officially notified of legal proceedings.

The other methods listed, while they may offer various levels of service, do not provide the necessary proof of receipt in the same way. Regular Postal Mail and Standard Delivery Service do not guarantee that the recipient will acknowledge receipt, which is vital in legal contexts. Priority Mail, although faster than regular first-class mail, also lacks the signature verification process inherent to Certified Mail.
