An NRI marriage fraud case can involve different legal remedies depending on the nature of the fraud, such as concealment of an existing marriage, false promises, financial deception, harassment, or misrepresentation of employment or immigration status.
The affected spouse can consider filing a police complaint or FIR where the facts disclose a criminal offence. Depending on the circumstances, provisions relating to cheating, criminal breach of trust, cruelty, forgery, or other applicable offences may be relevant. If the marriage itself was obtained through fraud or material concealment, the spouse may also have grounds to seek appropriate relief before the competent family court, including annulment or divorce, depending on the applicable personal law.
For an NRI spouse living abroad, the person should preserve marriage certificates, messages, emails, financial records, travel documents, and other evidence of the alleged fraud. If proceedings involve another country, jurisdiction and service of legal notices can become important issues.
Because the appropriate remedy depends heavily on the facts and the laws applicable to the marriage, it is advisable to consult a family-law or criminal-law lawyer in India before taking formal action.
