Benefits on ex-spouse's record after remarriage abroad

I would advise you explore this further, but indications are that you would not be eligible for benefits on ex-husband's record.

If you remarry, you generally cannot collect benefits on your former spouse's record unless your later marriage ends (whether by death, divorce or annulment).

In my limited experience, at least with immigration issues (folks coming to the US), foreign weddings are recognized. I am unsure about how Social Security views foreign weddings, however.
