If i take a photo of any thing in disney world can I sell It? with out a contract or lease of rights?

No. You would have to get a release from the owner of the property. While Disney allows anyone to take photos for personal use at Disney World, you would need their permission to take commercial photographs on their property, which would come in the form of a photographer's location release. Disney employs a bunch of photographers in order to sell photos in the parks, so don't expect a location release to be freely given.
