Well, it looks like Jude was a nobody while Layla was from a somewhat prestigious clan of mages, it wouldn't be strange if he deided to take on her name for business purposes (a corporation associated with a big family should have somewhat bigger chances in the market), or her clan demanded him to take her name and not the other way around if he wanted to mary her.
