I bought 1 bed flat and had completion done in July 2022. At the time of completion, leasehold company clear all the dues and specifically mentioned that some invoices will be issued in September 2022. Now completion is done in July 2022, leaseholder company send pending invoice in September 2022 for the work done during period March 2021 to March 2022 when seller was lease holder. When we contacted seller's solicitor to pay this invoice as those dues are before completion date, their solicitor refuse to pay the pending Invoice and said the invoice has been received after completion date and no matter when work was done, they will not going to pay these invoices. so my question here is who is actually legally have to pay , me or seller and if they have to pay then what will be the legal action i can take on them to pay all their pending invoices? Thanks in advice for advice and help.
