1. Knowledge of the order on visitation by him can be proved by showing his or his legal representative presence on the day it was orally announced or a copy dasti allowed by both sides.
2. Position to fulfill that order can be proved if he left after 4th. May with knowledge of the Order is another pre-condition.
3. Then only any willful disobedience of that order comes into picture to get releif by your side and since it might have been filed under S. 10 and S. 12 of Contempt of Court Act, 1971. Both Sections of The Act, 1971 are civil in nature so que. of surrendering passport does not now arise via this Application / in such applications as passport surrender issues comes under criminal law domain.
But, here is a interesting case brief where HC Notice after some admission pleadings may not even be serviceable to him if his erstwhile family remaining here in indian soil refuses to receive the Court Notice which they have full right of as STATUS of spouse is changed. Now dependent upon already filed Memo of Parties if there is a mention of alternate service address there i.e. say of his US address / Employer address then only it could route through concerned Ministry in Delhi that also after lot of persuasive pressing civilian under the table pleadings - there goes few months / year to chase babus in Delhi and further follow up in Arizona’s with a local professional bailiff(s) that also if Indian Consulate General's Office in Ariziona convinces local County Court to service bailiff Notice in a civil matter whose Signatory India is not!. Now meanwhile even if your side manages some ex-party Order on alleged civil Contempt then I reserve serious doubt if it can be Executed as it will be against well laid principles of Natural Justice to respondent ex Husband side !

Both have far reaching legal meanings while giving replies by me which I already inked based on reading separated status ! However this is not a blame I am throwing on board I understood people come here with laymen's knowledge of Law.
PS: Lady I sincerely wish you the very best now that you have reviewed all available remedies and allow me to clean from this board discussion and let others share their wisdom if any on pressed facts, as I have nothing more to value add to this query in absence of date of his leaving.
