It can happen. In extreme circumstances it could even happen after your last payment, but before the completion certificate is issued and, if fraud or somesuch is proven, even afterward if the courts rule to set the arrangement aside.
If it does you are back to square one with your creditors, the monies paid in will be more than eaten up in fees and the interest the creditors are then entitled to add back on at the original interest rate and they will be able to pursue the debt by any means they consider reasonable.
But this harsh outcome can usually be avoided with a little communication with your IP.
My opinions are merely that .. opinions based on experience. Always seek professional advice.

Looking at his previous posts, I believe Darcus is concerned about his partners income which may drop drastically soon.

I note I didn't reply to the full post - the payments made to date will normally be used to cover the costs and anything left over will normally then be used to pay a dividend to the creditors.
