The sale of my house (title WA83789) has been delayed for several months due to the discovery that a small corner of my rear extension was on land still registered to my neighbours. An OS error in plotting the position of the boundary fence then held up submission of a TP1 form and deed plan while the OS made the correction and took nearly two months to publish its map revision. My neighbours' solicitor's slowness to respond to mine then caused weeks of further delay. My buyers have now waited for nearly a year since making their offer and the sale is at risk. I am struggling with the seemingly interminable anxiety and unforeseen financial consequences of all the delays. My solicitor finally submitted the TP1 form to HMLR early this month followed by a request for expedition and I understood that processing might be possible within 10 days to enable the sale, which depends on the part transfer, to move to completion. However, I've so far heard nothing further and have since read that HMLR can take about two weeks to approve an expedition and is not obliged to do so. Please can you clarify when I can expect to hear a decision and timescale and if there is anything I can provide myself to support the expedition request? Any help or guidance you can provide would be much appreciated.
