EE and spouse divorce. QDRO was signed by divorce judge and presented to PA. PA is processing the determination re the order for its status as a QDRO, when the ex-spouse informs the PA that she and the EE are going to get back together in a couple of months. I vaguely recall something several years ago about some airline pilots having gone through phony divorces to get QDRO payouts of benefits. Is there a case citation or DoL ruling/announcement anyone is aware of about that situation?

It was an advisory opinion. No cite off the top of my head, but it should be easy enough to find on the EBSA website collection, if not in one of your services.

Don't know if your situation is "sham" or simply "remarry".
Some discussion here.
