As far as i know, if someone will get married under father sponsor then, she need to transfer her sponsorship to his husband. However, i know that MOI revised some procedures regarding husband sponsorship, probably its better if you can personally drop by at Immigration Office to check the new requirements rather than inquiring from here, so you can have the first hand information from the officer.
Your Title is fine, however, if your office can change it to your official title...probably its better.! GoodLuck!
