This film was Mukul Anand's first film as a director. It was a song-less film with background score by Salil Chowdhury.
"Pulstar" by Vangelis is used as background music during the opening montage of the film when the police are shown arresting several criminals.
Suresh Oberoi and Deepti Naval were not on talking terms before the film. When they signed the film, they put all their personal differences aside to make the film work.
Deepti Naval did not want to accept the film because she had to play a mother. She was told the daughter would be 7 years old. When she arrived on the sets, she was shocked to find the daughter was actually 16 years old. She felt the audience would not accept this.
Mukul Anand stated that with Kanoon Kya Karega and Aitbaar he got the stigma of a video director, meaning a director who would steal scenes and ideas from English movies on video and then replicate those scenes in his Hindi movie the next day. Mukul stated he had to fight a lot to make these two films different from the originals. Mukul stated if anyone was to watch both the original and remake on the same day they would realize the visuals were different. Dial M For Murder was shot in one drawing room but for Aitbaar, Mukul Anand showed storms and a lot of other things. Mukul also stated he never denied where he got his inspiration from. He was always open about remaking the films of Hitchcock (Dial M For Murder) and J. Lee Thompson (Cape Fear).
