PM Law, a network of firms trading under a single umbrella brand, specialised in personal injury, wills and conveyancing.
According to its website, it employed more than 600 people at firms including Proddow Mackay, Butterworths Solicitors, WB Pennine Solicitors and Angela Viney Conveyancing Services.
This included offices in Ilkley near Bradford, Brighouse in West Yorkshire and Kendal in Cumbria.
Some clients who spoke to the BBC said the closure left them stranded mid-house sale or liable for two active mortgages after redemption payments were not made.
Similarly, staff said they were devastated to discover they had lost their jobs through a notice posted in the firm’s windows.
The BBC has made repeated attempts to contact PM Law at their Sheffield headquarters in person, by telephone, via email.
We have also put questions to them via the SRA and the law firm appointed as intervention agents by the body. In addition, we have put questions to a number of senior staff via business social network LinkedIn.
The SRA said its intervention agent, Gordons LLP, had taken possession of files and money, including clients’ funds, held by the firm, and was “diligently” working through tens of thousands of files.
Further details on how Gordons LLP will be supporting clients are available on the firm’s website, external.
