what are the docuements we got from builder?

Hi,
When i bought my property in 2010, i consult a property lawyer and he gave me a list of documents that i needed to furnish from the builder, he checked them and gave me a written opinion that the documents are in order and hence i can go ahead for buying. These are 1) Sale Deed, 2) Latest tax paid receipt, 3) Mother deed, 4) Encumbrance Certificate, 5) NOC from fire fighting dept., forest dept. and airport authority etc., 6) sanctioned building plan, 7) Title Document, 8) Approved lay out plan, 9) Conversion Certificate, 10) Commencement Certificate, 11) completion certificate and, 12) Occupancy Certificate.
