New York and New Jersey-based Moses & Singer has sued one of its former partners for $1.74 million, seeking to recover money the partner borrowed on the same day he and the firm settled an ex-client’s legal malpractice lawsuit seven years ago.

Since borrowing $1.173 million from Moses & Singer in November 2012, Stephen Weiss, who now works out of his own law office in midtown Manhattan, has only paid back $14,500, the law firm claimed in filings Thursday in New York County Supreme Court. Weiss allegedly owes Moses & Singer $1,158,500 in principal and $582,637 in interest, the latter of which grows $407.63 a day.
