You got a ticket for using a handicapped space in a private lot with the owners permission How can you fight it?

To contest the ticket, gather evidence that supports your case, such as a written statement or email from the property owner granting you permission to use the handicapped space. Document any relevant circumstances, like signage indicating the space is reserved but not enforced. You can then appeal the ticket through the appropriate channels, providing your evidence and explaining the situation clearly. If necessary, consider seeking legal advice to strengthen your case.
