Civil Suit - need urgent assistance

Contact a local advocate.  If you are in possession. remain in possession.  You can implead yourself and go for appeal in expartee judgment.  Move swiftly as this is not final and only injunction agaisnt alienation further from that date.  The issue can not be guided through forum and facts are to be linked to when the land was sold, the date on which you took possession, the knowledge to the other party, whether your seller is having possession on behalf of his other co sharers etc.

Sir

This was my reply:  Contact a local advocate

Even though you are not a party, there are cases where the parties collude within themselves and in view of this, as you are in the possession and having a legally valid title, you can implead yourself.

In the case of obstruction of the survey, you have to make an application for Polie security and get the land surveyed.

There is something missing in your query, injunction for what?  Is it a stay order?

A local advocate can guide you better on knowing things and if your interest is adversely affected through this judgment, he can file such impleading petition.
