Can I claim the rights of the agriculture land I bought on my wifes name

Dear Sir, I bought a land on my wifes name (my father in law acted as a representative in this transaction) since me and my wife lived abroad while making the land purchase. I transferred the money to my father in law and his associates to assist in purchasing the land , which was registered on my wife name. However situations changed now and my wife filed for a divorce in USA and dosen't want to come back. And ex-party divorce has been issued. Question: 1) How do I claim the rights on the property back which was all funded by me but registered on my wife name ? 2) My Father in law purchased this land for 50 lacs, but registered this only for 12 lacs in the government sale deed. (All this amount funded by me) 3) What kind of a law suit can be filed (under which section) to request the court to grant rights of this property to me. 4) We also have a Son, hence can I request the court to move this property on my Sons name and keep me as a guardian, Reason I am asking is , we are now divorced and hence I need to secure that property by claiming legal rights or atleast transfer this property on my son's name to cover maintenance from side.
