4. Father alone CANNOT legally sell the undivided house, while you are in possession. Publish newspapers notices that House is not for sale and no transaction shall be legally valid. Do this thru a local Lawyer. Issue Caveat to local registrar of sub-assurances, not to register the undivided house, since you have claim and you do not wish to Sell.

Section 14 of Hindu succession act describes what constitutes a woman’s property—both movable and immovable, owned and acquired by her. It does not distinguish between inherited and the self-acquired property. It  includes all property obtained through ‘inheritance or devise, or through partition, or in lieu of maintenance or arrears of maintenance, or by gift , whether a relative or not, before, at or after her marriage, or by her own skill or exertion, or by purchase or by prescription, or  by any other manner

2. You should apply for succession certificate from Court to get equal share from your mother investments.

3. He cannot sell undivided share until the property is transfered on name of legal heirs of your mother.
