Not quite correct. You will be sent a list of questions from your solicitor for your prospective purchasers solicitor which require you to give answers such as ground rent, maintenance costs etc.plus details of your management company and freeholder(might be same person in your case). When you have completed the forms they go back to your solicitors to forward to your purchasers solicitors.
Purchasers solicitor will then send a list of 'silly' questions to management company who will then cheerfully charge(you)silly money for answering them.
My best advice is for you to contact your solicitors to confirm/ask what actions you need to do next. It is what you are paying them for.
Hope I have that right and it helps
