They would each need to be able to provide proof of FL residency. If one or the other does not have this proof, they cannot use a FL Resident ticket.
From the WDW website:
For each ticket or pass purchased for an adult, you may provide any of the following:
- Valid Florida driver’s license (must have a Florida address)
- Valid Florida state-issued ID card (must have a Florida address)
- Valid Florida-based military ID
*For your convenience, Florida residents with any of the above listed identification can now verify their residency online, which means you can bypass Guest Relations and go straight to the parks! Simply fill out the “Your Florida Resident Information” form upon check-out when you purchase tickets through
Disneyworld.com or complete the “Customize Your Tickets” step when you purchase through the My Disney Experience app.
If you do not have one of the IDs indicated above, then you must provide one of the following—dated within the past 2 months—evidencing a Florida residential address, along with a corresponding picture ID (passport, driver's license, state identification card):
