I would need more info and I'd like to see the agreement, but if the agreement states that if she gets remarried, that you get your retirement back, then that would likely be enforceable and you could get a court order compelling the retirement plan administrator to return it to you. The tricky part will be enforcement. You might consider registering the case for enforcement in Colorado courts, since neither of you live in Nevada anymore, and then she will have to fight you here. I offer a free consultation if you would like to discuss this further. I hope this helps.
