Mandi is correct. Rules, applicable to sponsored wife and sponsored husband are different.
also, AB, if you have sponsored your husband it doesn't mean it applies to everyone equally and by default. there are certain criteria and whole list of the requirements and rules, which are getting tighter and tighter literally day by day. ALso, regarding your "contract". I am not sure when and where did you get your contract, but Marriage certificate attestation is a must as per latest requirements. again, do NOT assume that your own experience is a RULE.
(oh, com'on now.. what is that new 700 characters limit?? It prevents you from giving a comprehensive answer! Anyway, to be continued..)
