Newly married couples cannot file a petition for divorce within one year of marriage. When was your marriage ?
498A case is not adversely affected .If your family members names are evicted from charge sheet so they are released from 498A case so your brother has no problem .More over Hon'ble Supreme Court stated 498A false cases as Legal Terrorism, 90% of the cases are fake and it has become a business to some unscrupulous women who want to extort money in the name of marriage. Only 10% are genuine cases. Now 498A is ultimately USED as a gamble. These women file cases at the advice of their lawyers, close relatives with vested interests or just to persecute the hubby and in-laws or to defraud the hubby and his family as they know that this law is actually designed to be more effective as a tool for extortionists and blackmailers than for protecting women facing dowry harassment or domestic violence.
