Not really though, in the article TS posted oso says that if they didnt show signs like "park at your own risk" or etc to you before you hand the car to them, its still their liability. Moreover, in the agreement act, once they collect parking fees from you when you park your car in a parking premisis, a mutual agreement occur that they are liable unless the parking is free. Just look at the Canny Ong case, the parking company is liable for the case too even they have a big "park at ur own risk" sign upon the parking entrance.
