Dear user,
Criminal intimidation (threatening) is defined under Section 504 of the Indian penal Code and the punishment under Section 506 includes 2 years or fine or both, or 7 years or fine or both, in case of threat to death or grievous injury.
In your case when the person refuses to give the property papers, you can file a criminal suit in the court with proper proof that you also have your share in the said property.
Apart from this, you can also file a suit for criminal intimadation.
I hope I was able to solve your query and please leave follow up questions, if any.
