I have had similar requirements in the past, I solved them using FoolProof. It provides extra validation objects such as requiredIf etc.

Only issue I have had is with the JS file, it can be a bit buggy around dates and date handling, other than that, it is ace.

I've also used Foolproof. Works like a charm. Issues with dates can be solved by using globalize.js, but that requires changes in code. https://github.com/jquery/globalize – kubal5003 Nov 28 '12 at 10:40
