How to file a criminal case and who should file

RESPECTED SIR/ MADAM,

MY BROTHER WAS BOOKED UNDER 498-A FALSELY IN 2011. SUBSEQUENTLY HE WAS GRANTED BAIL AND THE PROCEEDING ARE GOING ON IN KAKINADA COURT.  ONE AMOUNG THOSE ALLEGATIONS IS THAT MY BROTHER'S FATHER IN LAW HAS GONE MISSING FROM HIS HOUSE DUE TO THE CONDUCT OF MY BROTHER.  FURTHER THEY HAVE ALSO PRODUCED A FABRICATED SUICIDE NOTE WHERE IN IT IS MENTIONED THAT DUE TO MY BROTHER'S MISCONDUCT HE IS LEAVING HIS HOUSE.  MY BROTHER RESIDES AT CHENNAI, TAMILNADU AND HIS FATHER IN LAW, WHO IS RETIRED FROM STATE GOVT SERVICE FROM ANDHRA PRADESH WAS STAYING AT KAKINADA, ANDHRA PRADESH.

WE TRIED TO PROBE THE MATTER OF THEIR FATHER'S ISSUE.  IT WAS REVEALED THAT THE SO CALLED LEGAL HIERS, I.E MY BROTHER'S WIFE, MY BROTHER'S MOTHER IN LAW AND THE OTHER TWO SISTER IN LAWS HAVE SOLD ONE PROPERTY STANDING IN THE NAME OF MY BROTHER'S FATHER IN LAW  AFTER HE HAD REPORTEDLY GONE MISSING.

DURING THE EXAMINATION OF WITNESS OF 498-A THIS QUESTION WAS POSTED AS TO THE WHEREABOUTS OF MY BROTHER'S FATHER IN LAW. INITIALLY MY BROTHER'S WIFE HAS STATED IN THE COURT THAT HER FATHER HAD GONE MISSING.  SUBSEQUENTLY WHEN THE XEROX COPIES OF SALE DEED DOCUMENT WERE SHOWN TO HER IN WHICH IT IS STATED THAT HER FATHER HAS ON A PARTICULAR DATE AND HER STATEMENT WAS CONTRADICTORY.  SHE CLAIMED THAT BOTH THE FACTS ARE TRUE.

WHEN THE SAME QUESTION ABOUT THE WHEREABOUTS OF MY BROTHER'S FATHER IN LAW  WAS POSTED TO MY BROTHER'S MOTHER IN LAW  SHE INFORMED THAT SHE HAD ORIGINALLY MENTIONED TO THE DOCUMENT WRITER ASKING HIM TO MENTION THAT HER HUSBAND HAS GONE MISSING IN THE SALE DEED, BUT THE DOCUMENT WRITER HAD BY MISTAKENLY MENTIONED HIM DEAD.

NOW I WANT TO FIND OUT WHETHER ANY CRIMINAL CASE CAN BE FILED AGAINST MY BROTHER'S MOTHER IN LAW SINCE SHE IS GIVING CONTRIDICATORY STATEMENT IN THE COURT ABOUT HER HUSBAND'S MAN MISSING ISSUE.   THE HAVE EVEN SOLD A RESIDENTIAL PROPERTY AFTER REPORTING MAN MISSING  CASE IN POLICE STATION.  I AM UNABLE TO UNDERSTAND HOW THE REGISTRAR HAS AUTHENTICATED THE SALE WHEN THE ORIGINAL TITLE HOLDER HAS BEEN REPORTED MISSING.IN THE YEAR 2010-11.
