- Since, the said property is registered in the name of your wife , then your father was not having any right over the same without getting a valid document in his favor.
- Further, as per Supreme Court Judgment , a property cannot be transfer without a registered deed , and hence the said Rs.100/- stamp document having no legal value in the eye of law, and hence that lady is living there just like a trespasser.
- Further , as she has forged the signature of your wife , then you can lodge an FIR against that lady for the offence of trespassing and preparing a forged documents with a fake signature.
- If the police not taking any action within 7 days , then you can file a criminal compliant before the magistrate after submitting that compliant given to the police
- Further, out of this complaint , you can also file a Mandatory Injunction suit before the court for vacating her from the property .
Good luck, and don't forget rating positively.
