To protect your lottery ticket, sign the back of it immediately to establish ownership. Store it in a safe, secure place like a fireproof safe or a locked drawer, ensuring it's protected from damage or loss. Take a clear photo or make a photocopy of the front and back for additional proof. Avoid sharing details about the ticket publicly. When claiming the prize, follow official procedures and avoid handing over the ticket until necessary, ensuring you maintain full control of it until the claim is validated.
