Part of the easement states: "If any maintenance, repair or reinstatement of the party wall has been rendered necessary by the act of one party alone ... then the party at fault or responsible shall bear the whole cost of such work."
More specifically it also bans either neighbour from carrying out any works which may expose the other tenant to the risk of damage, without prior written consent - which Mr Alwahb hasn't given.
John Gray of the Home Owners and Buyers Association [Hobanz] discovered the contents of the easement and said this meant Mr Alwahb had a legal standing to immediately halt Mr Davis and Ms King's proposed development.
Karen Kemp, property lawyer and partner with Anthony Harper, said she was liaising with Mr Alwahb about his options.
"It is our aim to ensure that the security, safety and value of Mr Alwahb's home is preserved. For any homeowner, the simple requirement is that costs incurred because of the actions of another should be borne by that person. We are working with Muhannad to help him resolve the situation, but no demolition work should be carried out in the meantime and we will take immediate action to halt the demolition, if necessary."
