The simple answer to that is filing an application for contempt of court. Contempt of court is basically an act of deliberate disobedience of, or disregard for the instructions of a Judge.
In today's Trinidad and Tobago Newsday newspaper, there is an article with the headline Mom faces jail if she fails to give up son to ex-husband.
In the article, Dianne Dabiedeen, refused to allow the father, Rajpat Dabiedeen to have access on weekends and during school holidays to their 14-year-old son, Richard Matthew Dabiedeen.
The order, which was made in March 2014 was never followed, so Rajpat filed a "Contempt of Court" application.
As a result of that application and hearing, Dianne must now follow the order or face seven (7) days in jail.
Which option do you think she'll choose?
