Statutes

Part of this rule relies on secondary sources rather than the statute itself, and has not yet been confirmed by a lawyer.

Certified mail is recommended practice here, not a statutory requirement.

Step by step

  1. Write the notice with every required element (the New York template in Cortul already has them).
  2. Verify the recipient's mailing address with USPS.
  3. Send it by a method the law allows, and keep a mailed copy.
  4. Keep the mailing and tracking records, and your own record of any service you did yourself.
  5. Calendar the deadline from the mailing date.
