Not sure. This site is the one that belongs to the entity that will register your car. It is Sumter County
Tags & Registration - Randy Mask - Sumter County Tax Collector . Not the town of Lady Lake. If you are in Lady Lake then your county is Lake & they should have a similar website. In any case, the directions I see for registering your car refer to a state, not a country so you may have to call them to find out. But they may be very similar. ie: proof of you are who you are & you own the car. The following was taken from the above web site.
"To register your vehicle in Florida we will need the following:
All registered owners must be present. If one or more registered owner is not able to be present in the office, this packet or this form will need to be completed, with original signatures
Photo identification- State issued driver’s license or ID card for each registered owner
Original out of state title (If you have a lien on your vehicle you will need to ask for a letter of request from our office to have the title released to us for registration)
Proof of FLORIDA insurance through a FLORIDA agent; (a card, policy or binder will need to be shown in office)
The vehicle for VIN verification weather permitting, or a completed form HSMV 82042
Bill of sale if vehicle has been purchased within the last six (6) months"
Hope this helps, let us know what you find out & your success story.
