Beware of Married Men on AllMovie

Irene Rich plays the secretary to divorce lawyer Rush Hughes. Though in love with her boss, Rich resists marriage, having been soured on matrimony by Hughes' cheating clients. Meanwhile, Rich's kid-sister Myrna Loy is being squired by a married man, whose wife has dispatched detective Clyde Cook to get the goods on her philandering spouse. Disguising herself as an elderly member of the "Welfare League," Rich gains access to the home of Loy's clandestine sweetie, in hopes of scaring off the two-timing hubby. Instead, a series of slapstick misunderstandings ensues, with poor Cook in the center of the confusion. When all is said and done, Rich marries her employer Hughes, which she could have done in the first reel and spared the audience the rest of the picture.
