Grounds for Marriage is a 1951 American romantic comedy film directed by Robert Z. Leonard.

Written and produced by Samuel Marx, the film stars Van Johnson, Kathryn Grayson and Paula Raymond.

Ina Massine (Kathryn Grayson) is an opera diva who divorced throat specialist Dr. Lincoln "Linc" I. Bartlett (Van Johnson) three years ago.

On the night of the premiere of her latest opera La Bohème, Ina is bothered with a sore throat and calls Dr. Young.

Young advises psychiatric help and tells Linc that a new love interest for Ina could solve the problem.

Although Linc assures Agnes several times he has no feelings for his ex-wife, she remains suspicious of his connection with Ina.

Linc contacts his brother, Chris Bartlett (Barry Sullivan), hoping he will be able to romance Ina.

A couple of nights later, with Ina staying in his apartment to take care of him, Linc, suffering from a severe cold, is bothered by a feverish nightmare.
