Ex not complying with Sep Agreement

I’m divorced. Sep Agreement included 2 houses being allocated to ex. She has until Sept 1, 2011 to “…refinance or otherwise remove my name”. She’s claiming that she can’t afford to refinance, and doesn’t want to sell one of the houses.

What recourse do I have?
What might be an expected outcome?

You need to file a breach of contract action to enforce your Agreement.
