Quoting
Mr. Knowitall
The general rule is that divorce terminates conditional permanent residence. You would want to apply immediately for a waiver of the termination based upon whatever facts you can present to establish that the marriage was a union in good faith and the you were not at fault for the failure/inabiity to file a joint petition to remove the condition. I suggest consulting an immigration lawyer with the details of your case.
Your spouse may also want to talk to a probate lawyer because it may turn out that the clause that has her so afraid of losing out on money isn't even enforceable.
