Yes. You, as owner of the property, are responsible for the charges up to the time that the property is legally transferred to the new owner. Absolute Property Management issue a receipt which you give to your Solicitor at the time of the sale and your Solicitor will apportion the costs and recoup the balance from the purchaser. At the time of the sale all outstanding management charges will have to be paid to date and the sale cannot be completed until the outstanding management charges are paid.
