Does anyone know if a consent can order be changed/overruled? If so, how

It was set two and a half years ago and rested on the house being sold. It still hasn't and in the meantime I have lost my job. At the time I agreed to almost everything just so that he would sign and I could get away.

I agree with Babybarrister. It's very unfortunate, but the court only very rarely sets aside consent orders, usually where there's been an element of fraud, eg one party hasn't disclosed a significant asset.
