In a very difficult and out of the hands situation I filed a criminal case against my husband,in-laws and on a married woman(outsider to the family, hindu but different community).After that my husband filed a o.p for divorce under cruelty and desertion, mentioning false allegations,adultery and described me as thief,ruthless, characterless woman and heartless mother of two kids(now at the age of 6 yrs daughter and 5 yrs of son) and even trying to question their birth also. In depth, We reside in telagana due to private job with less salary, but our matrimonial home is in A.P. provoked by my in-laws,my husband deserted me 6moths before without a valid reason.After a mediation, by suspecting he is going abroad with another woman, just to stop him I signed a criminal case filed by my lawyer with sections 496,493,425,426,415,417,420,120b,109,294-B, 323r/w,34 IPC,156(3)-Crpc (I don't know anything about this secs)on total 4 members, a1-husband, a2- other woman,a3&a4- in-laws.On back door they bailed in one day without counceling. After this,facing lots of struggles to coneince them for to talk,I tried for reconciliation and agreed for all his conditions and agreed to take back my case applying my guilty (his condition for reconciliation). After all these also,I received divorce notice which he filed just two days before our meeting which is pre-planned by them. In that petition he claimed that I deserted him 2years before,and he tried alot to recouncil,I filed false cases to harace them.
