suit for measurement of property and fencing

Demarcation of land falls within revenue jurisdiction, where you have already stated to have filed a case, can you not wait for the outcome of the same ? 

Even then if you so desire, yes, you can flle a suit for declaration, permanent and mandatory injunction against your neighbour, who have encroached upon the land purchased by your deceased father.

Why do you not move to the High Court for a writ of mandamus and/or necessary directions to autorities concerned and the encroachers under Article 226 and 227 of the Constitution of India ?

So impatient ???

When you have waited for decades for the same issue, when the country is reeling under severe epidemic, do not expect that Court can come to your rescue.  The problem exists in all offices including courts and finally it is the Surveyor that has to measure and certify.  There is a laid down procedure for such a survey and intimating the boundaries property owner is one.  You can also get certified copies of boundaries properties from the Registrar office and cross-check your documents.

To file a civil suit, there need to be a cause of action; the facts posted suggests none. As such, the only option is to get the property surveyed and demarcated through the Taluka surveyor.
