Transfer of chs share to co-owner name

Both my daughters purchased an apartments in ‘Splendor Complex, Andheri East, Mumbai’ directly from the builder. The agreement with the builder was registered in Joint-name of both sisters in 2011. Subsequently Share Certificate by the ‘Splendor Complex CHS’ was also issued in the Joint name of both sisters. In 2015 Sister ‘A’ executed a registered Gift deed gifting her share in this apartment to Sister ‘B’ and required Stamp duty and Registration duty was duly paid and deed was registered with sub-registrar office. Presently the Share Certificate of Society is in both sisters name. We wanted to get the Share Certificate endorsed in Individual name of Sister ‘B’ and had submitted the following documents to the society office for this: 1. Copy of Registered Gift Deed. 2. Original Share Certificate (in joint names of two sisters) for Transfer to Single name (one sister). 3. Transfer fee receipt of Rs 700.00 But society office has returned the above and has given us a ‘Scrutiny Sheet for Membership Transfer’ but have not clarified which forms out of these are applicable in our case. Scrutiny Sheet mentions the following: 1. Appendix 21 2. Appendix 20 (1) 3. Registered Agreement 4. Transfer Fee 5. Form 23 6. Appendix 20 (2) 7. Appendix 13 8. Appendix 25 (1) on 100 Stamp 9. Appendix 27 10. Appendix 3 on 100 Stamp 11. Appendix 25 (2) on 100 Stamp 12. Committee Meeting Reso 13. Form 25 on 100 Stamp We need your advice as to what forms are we supposed to be sending to society office along with Following: 1. Copy of Registered Gift Deed. 2. Original Share Certificate (in joint names of two sisters) for Transfer to Single name (one sister). 3. Transfer fee receipt of Rs 700.00
