Under section 137(1)(b) of the Bharatiya Nyaya Sanhita, 2023 (formerly section 361 IPC), kidnapping from lawful guardianship covers taking or enticing any child, or a person of unsound mind, out of the keeping of the lawful guardian without the guardian's consent, and section 2(3) defines a child as a person below eighteen years of age. So a female can be kidnapped from lawful guardianship so long as she is "under 18 years of age".

Sixteen was the old IPC limit for a male (now also eighteen), and neither fourteen nor twenty-one is the statutory limit.
