I am in a similar position,but my Consent Order has only just been approved. Mines states FMH to be sold and proceeds of sale to me. Ex would not allow me to sell until absolute (no reason for this as he is not getting any equity....other than to be spiteful, but then said he would agree if I gave him an additional £20k outside our financial agreement). I received an offer in March (just before lockdown) and he refused until absolute, which I now have, buyers still interested and so I have instructed conveyancer, but ex will not sign the papers. He lives abroad. My understanding is you need to complete a D11 form for breach of consent order. Initially, you need to write to him to advise him that you are writing to court as he is in breach of consent order and give him 7 days. However, as he is abroad (my ex husband is also) I am not sure how things stand regarding court and whether they can enforce the sale if it is abroad. Maybe someone else can advise on this. Sorry I couldn't really help, but just wanted to comment as mine is a similar position.
