KANSAS CITY, Mo. - When you buy a ticket, print it and you finally have it, do you have any idea what to do with it? An unsigned ticket is the property of whoever turns it in.
Lottery officials urge you to sign your ticket immediately. Money expert and attorney Chuck Andres suggest you go ever farther and take a "selfie" of you and your ticket.
"Take the camera, take a picture so it's clear so on this date, this time, you had this ticket and you are in possession of it," Andres said.
If you buy a winning ticket in Kansas you can remain anonymous but if you buy it in Missouri you have to identify yourself to the world.
"Make your announcement," Andres said, "on your way to KCI."
That way you and your winning ticket can get some anonymity and duck out for a while, he said.
"So that people like you don't come and ask what you are going to do with the money," Andres joked.
