Reception
The Hindu in its review of the film, quoted: "In a remarkable scene, where Rajesh Khanna, his anger simmering, confronts Mumtaz, the director, J. Om Prakash, brings out the performer in both. Mumtaz brings compelling expressions to her countenance as her initial disbelief at being doubted by her husband is transformed from anguish to fury in a flash. This remains the standout moment of the movie apart from the song "Zindagi Ke Safar Mein Guzar Jate Hain Jo Maqaam". Sampada Sharma in her retrospective review for The Indian Express stated "The film has a lasting effect, and that is mainly because it does not pander to the idea that life is an endless pool of opportunities. Aap Ki Kasam might not be the most forward-thinking film of its time, but it certainly was one of the most unique mainstream films that came out of this era."
