This is my response to you:
1. You will have some original property papers with you? Which are they? Or atelast a few xerox copies?
2. Since you do not have papers, engage services of a local lawyer;
3. The lawyer will help you with draw out the succession certificate (legal heir certificate), the title search report of the property, find the previous owner/s, trace copies of the property (xerox or authentic), retrieve 'true copies' of your property from the registrar, also find the stamp duty and registration paid;
4. Once all the papers are there, or the 'True Copies' (stamped by the Registrar), with that you can sell the property to a new owner;
5. While selling you can also issue a indemnity bond, an NOC (waiving off your claim in the property in the future) also take out advertisement in the newspaper inviting claim on the property;
6. Once you trace all the papers, complete formalities from your end, you can effectively transfer the property to the new owner.
