Manhattan law firm D’Amato & Lynch said in recent court filings that its own legal malpractice insurer has refused to cover its dispute with an insurance company over a $1 million check that it deposited in the wrong bank account.

Meanwhile, the insurance company that brought suit over the $1 million check, First Mercury Insurance Co., is seeking to put the firm in the hands of a receiver, asking for a constructive trust to be imposed over its assets and those of Luke Lynch Jr., who is described as the firm’s general partner.
