Dear Mr Kathuria,
The wordings of your query are very confusing. But what I could understand from your query is that your sister had taken your shares document and now she is not returning them. Follow these simple steps :-
1. Request your sister to give back the documents. Tell her that if she does not give the documents within 24 hours you will report the matter to police. Try and involve some senior member of your family to resolve the issue. If resolved, good.
2. If she does not give it back, write a complaint to the police telling about the nature of documents and that they have been taken illegally by your sister. The police will themselves get you documents.
3. If the police does not act on your complaint, write a reminder and send the reminder along with original complaint to Superintendent of Police (SP) of your area. Send through registered post and keep the postal receipt. Also download the tracking report.
