Counsel's Opinion was based on a 1931 Gilbert Wakefield play and was remade, again by London Films, in 1938 as The Divorce of Lady X starring Laurence Olivier and Merle Oberon.

Logan accepts the brief, but then discovers to his horror that Lady Rockburn was a guest at the Royal Parks Hotel ball the previous night, and a cornerstone of the case is alleged impropriety after a maid observed a man leaving her room that morning.

When Leslie calls to return a dressing gown Logan lent her, he invites her to dine with him that evening, still believing her to be Lady Rockburn and intending to inform her of the situation.

The romantic evening comes to an abrupt end when Lord Rockburn shows up at the same restaurant accompanied by another woman, and Logan and Leslie are forced to make an unobtrusive early exit to avoid a potentially scandalous public scene.

As what would appear to have been a well-received prestige production of its day, with the involvement of names such as Korda and Dwan, Counsel's Opinion is included on the BFI's "75 Most Wanted" list of missing British feature films.
