suit for partition against my 3 brothers and a sister

You need to file suit for partition against your all brothers and sisters and have right to claim 3/7 share in land.

I concur with the advise of learned expert Sh. Bhartesh Goyal.

It is advisable to consult and engage a local prudent lawyer with relevant records for appreciation of facts, professional advise and necessary proceeding, if any problem / issue / dispute existed with you, which is prima facie a hypothetical exercise..
 

Since you siblings are seven in number and you are entitled to one share if divided equally, you can file the partition suit on your own if other female siblings are not willing to join you as plaintiffs.

You can arraign all the other siblings as defendants, and implead them accordingly in the proposed partition suit.

In that case you can file the suit for partition and for allotment of your rightful 1/7th share in the property with separate possession. 

You can include even the properties that have been sold or alienated without your consent or permission earlier.

Yes.  I agree with the advice of the above learned experts.

You can go for filing of partition suit in civil courts. A partition suit is filed when the co-owners do not agree to the partition mutually. A partition deed is a document created for dividing the property between the owners, as per the agreeable terms.
