The age limit for B.Com LLB can vary with the university and country. In India, the age limit for an integrated law program has been fixed by the Bar Council of India. Here the upper age limit is 20–22 years for open category students, but for the reserved category (SC/ST/OBC), the upper age limit gets extended up to 22–24 years. However, some colleges have no such restriction; that is, a student of any age can apply. Check the specific eligibility criteria of the college that you are interested to join.
Private universities and institutes that offer B.Com LLB typically have a more relaxed age limit. A few of the colleges accept students above the prescribed age line also, considering certain prior education and work experience. If not certain about the age limit, then visiting the university's official website or contacting the admissions office would be advisable in order to get the most accurate information based on the current policies.
