its quite long but broadly says--
no transfer or lease of the registered estate before 2020 by the proprietor of the property is to be completed without a certificate given by the mayor and burgesses of the London borough of Enfield that complies with section 156A of the housing act etc or is an exempted disposal or that the disposal complies with the requirements of the housing act section 156A.
I don't think so but I cant find out until tomorrow.
I did wonder about that, I will talk to my daughter in the morning.
do you recommend anyone?
Thank you for your help at the time. As it turns out Enfield have now agreed to issue the certificate based on a detailed letter about my daughters situation.
