Mr. Barrett is correct. You need a Texas attorney on this matter. You might want to repost this on the Texas Avvo site.

I don't know if one needs three attorneys saying the same thing, but the answer is to return to her attorney in Texas if she was satisfied with his/her representation, and if not, do an Avvo search for highly rated family law attorneys in the country or city where the divorce took place. Colorado attorneys will be of no help to you.
You would file any type of enforcement action in the same court where the divorce was granted. What type of Motion to file would depend on how the divorce decree is worded. It may be possible to file an enforcment against him or perhaps a Motion to Compel him to do what he was ordered to do. Another possibility is that he attempted to refinance and was not able to qualify. This is why I include a contingency plan for these issues. For instance, you could have had a decree order that the house be sold if it is not refinanced by a certain date. If the house is endanger of foreclosure you can file a Motion to Appoint a Receiver who will have the authority to sell the house, similar to a trustee. As you can see, this can be quite complex. You should contact an attorney familiar with the court where the Decree was granted for further guidance.
