The Share Transfer Agency (STA) maintains the record of all shareholders for the same of shareholder benefits and ownership transfer. The Company or STA, on receipt of DRF and share certificate(s), will process the request. If the DRF is found to be in order, i.e. verified signature and certificate(s), then it will automatically and electronically confirm the request. The DRF may get rejected for various reasons like a signature mismatch, mutilated certificates, duplicate certificates etc. In case of objections, you can approach your DP to help you through the process. Your DP will send all the documents to the STA because it is the STA that maintains the record of shareholders in its register.
