Under the Party Wall etc. Act 1996, retrospective awards are possible, but their validity and usefulness are limited. A surveyor can still assess the situation, document damage, set repair obligations, and create a formal record. However, a retrospective award cannot undo unauthorised work, prevent risk during construction, or provide the advance protections normally included in a standard Party Wall Award.
