Dear Sir/Madam,

When the father is alcohalic, the case can be filed against the father by the mother or some other guardian of the child for restraining the father from alienating the properties. 

1) only on demise of father would you inherit his property 

2) if it is ancestral property you can file suit for partition to claim your share in property 

If it ancestral property then minors can send a legal notice to buyer along with his mother name as well.

He can only get if he has share in the same. Being alcoholic doesn't give a right to take his property. You need to establish that the said property. He can reclaim the same

Minor should file a suit of declaration suit for declaring the ownership of the land via a guradian

1. If the said land is purchased by the father , then none can claim the same without his consent.

2. Yes, the minor through his mother or guardian can claim his share in the hereditary land from his father. 

- The minor through any guardian should sent a legal notice to his father to give him his share .

As per Hindu Succession Act, every legal heirs even child in wombs are also protected under Hindu Succession Act.

Please file partition suit before the Court of law to secure the share of minor in the property of Ancestral land.

If said property is self acquired by  father then minor cannot claim. 

if it is ancestral then minor can claim. 

The question is a complicated one and it is difficult to give the exact answer especially due to the very brief explanation of facts and very little detail provided by you. Still I will try my best to explain comprehensively in light of the details.

If you mean that you have a share in the land as a coparcener but you are not a recorded bhumidar/tenure holder in the revenue records, then you will have to go the revenue court like court of S.D.M depending upon upon your local revenue law and there you will have to seek declaration of title. However of you are recorded tenure holder then you may straight away approach civil court for cancellation of the deed of sale. This is for sold land.

For the land which he has not sold already you may approach the civil court and seek injunction against him from selling any further land.

This is assuming you have a share in the land and the land is agricultural land.

If the property was on the name of the by a registered document,  then the father becomes the absolute owner of the property hence he can sell the property at his own will and wish. 

The child whether minor or major cannot claim any rights in the property at least not during the lifetime of father. 

1. Yes through his mother he can file suit for cancellation of sales deed on ground that no permission were taken from court before selling property of minor. 

2. Mother of minor can file Suit for his as his legal representative and natural guardian for partition of ancestral Property.
