Father's property

get the public documents and file a partition suit

Four ceiblings along with mother entitled for equal shares.If not ageed, consult lawyer for proper advice and legal action.

File partition suit

Your father died intestate ie. Without a valid Will?

If there was a Will and in that he bequeathed property in your Mother's name, she can do as she wishes.

Another plot is anyhow in her name and her transferring to elder son may be correct unless you can prove that your father purchased property with his money in the name of mother. But the document favouring your mother needs scruitiny as to how the point of her acquiring the property.

Hello,

Your mother and your brother and sisters are having an equal share in the property of your father. You can even claim a share in the plot which is in the name of your mother as your father has purchased it. Take legal action against your elder brother and your mother for illegal transfer. 

What do you mean by  "Elder son and mother transferred property from fathers name to mothers' name and plot purchased by father from mother's name to his own name"? How was the transfer effected? Was any conveyance deed executed?

 

Greetings!

First of all, how can your mother and elder brother transfer the property on their name without obtaining NOC from rest of the Siblings.

Additionally, I advise you to consult a lawyer in your case to clear up the facts.

Thanks!

Seek partition of the properties.

It is advisable to consult and engage a local prudent lawyer for better appreciation of facts/ documents, professional guidance and necessary proceeding
