The requirements to vote in a referendum may vary depending on the country or organization that initiates the process. However, in general, to vote in a referendum, you must be:

• A citizen of the country or organization holding the referendum
• At least 18 years old
• Registered to vote

In some cases, you may need to be on a specific voter list, such as the Postal Voters List or the Special Voters List. To register to vote, you may need to fill out an enrollment form on paper or online.

On voting day, you will need to go to your local polling station, which will be named on your polling card. You will need to bring a declaration of identity, which will be witnessed by the presiding officer. You will then mark the ballot paper in secret, place it in the special envelope provided, and present it to the presiding officer. If you need help with voting, you can ask for assistance.

Its important to note that the specific rules and procedures for voting in a referendum may vary depending on the country or organization holding the referendum.
