Non-compliance with Consent Order

I divorced 6yrs ago but my ex continues to fail with regard to the undertakings & orders contained in the Consent Order. Whenever I have reminded him of his obligations, he uses it as an opportunity bully me (I divorced because of abuse)to the point that I have given up trying, most notably with regard to the RPI increase that is supposed to happen each year with regard to our daughters maintenance, there has been no increase since 2006. I have now managed to get myself together and at last feel emotionally strong enough to deal with a number of outstanding issues, although I do not want to waste my time attempting to deal with my ex again, therefore, what is the exact procedure for returning to Court to force him to fulfil his obligations. Do I have to return to the court that dealt with our divorce or can I use a local County Court. Is it possible to undertake this myself and what documents do I need.
Many thanks for your suggestions.

You can do this yourself its not that hard.

First write to your ex asking him to comply with the order in say 14 days or you will take it back to court and seek costs, doing it yourself you wont have any costs but its worth mentioning so he knows how serious this is.

I no joy download form D11 in the wiki library state you wish to have the terms of the attached order imposed by court, staple a copy of the order to D11, and take it to court and pay i think £45.

In time you and your ex will get a letter from court giving you a date for a hearing, you both attend and he will have chance to explain his actions, unless he offers a solid reason the terms will be enforced by the judge.
