If you suspect a release deed has been forged, especially if your photo and fingerprint appear on the document without your presence at the sub-registrar's office, you should take action. The primary recommendation is to file a case in court to have the release deed cancelled. It's crucial to clarify the exact circumstances, such as whether you signed the documents or if your fingerprints were somehow included without your consent. Consulting a local lawyer is highly advised for professional guidance tailored to your specific situation in Karnataka.
