WIFE WANT DIVORCE DEMANDING FAMILY PROPERTY/AMOUNT OF 20LAKH ON NAME OF 2 Yr SON

My wife with my 2 year son is living in her native place from last 6+ months. We tried full of efforts from every angle but she don't want to come back and want to get divorce as well as demanding property or 20 Lakh Rs on behalf of local panchayat. She also has gone with gold ornaments of 5 Lakh while going back to home, my in-law is also not accepting that she has gold. My earning is 10000 per month. Actually she has full eyes on my parents property, my parents is yet alive and yet property not divided among my father, mother, me and my brother. There is no property dedicated to me as well as my younger brother. Parents property is self occupied. (1) What type of claim she can do. What should I need to do.. (2) Do the compensation/maintenance of wife and son depend on family status or only on my income (husband) . (3) Is she authorized to get property of my father or 20lakh by name of 2 year old age son... or Does Grandson can claim Grandfather property after adult age..
