What is the procedure for repossessing a vehicle on private property in Florida?

You need not notify the vehicle owner.

It can be repossessed from a private driveway or yard. You cannot break into a garage nor threaten the owner with violence.

The person doing the repossession must be licensed by the State.

Within five days, you must send written notification to the owner, telling him to come get his personal belongings that were in the vehicle.
