After bifurcation, the Bar Council of Telangana was constituted separately, but advocates already enrolled with Andhra Pradesh remained validly enrolled there unless they opted for transfer.
Right to Practice Enrollment with any State Bar Council under the Advocates Act, 1961 allows practice throughout India, not just in that state. Since your friend’s name is still reflected in the Andhra Pradesh Bar Council records, his enrollment is valid. He can appear, file cases, and practice in Telangana courts without needing re-enrollment, because the right to practice is nationwide.
Transfer Option If he wishes to have his enrollment reflected under the Telangana Bar Council, he can apply for a transfer of enrollment. This is optional, but often preferred by advocates who primarily practice in Telangana, as it helps with local Bar Association membership, welfare schemes, and voting rights in that council.
Practical Steps Verify enrollment status with the Andhra Pradesh Bar Council (ensure his Certificate of Practice is up to date). If expired, he must renew his Certificate of Practice (COP). If he wants to shift, file a transfer application to the Telangana Bar Council. Meanwhile, he can start practicing immediately
