Dear Client,
You will have to file partition suit if he is denying to give you your share.
Only sale deed or registered agreement for sale is proof of ownership.
With the amendments made by the Hindu Succession (Amendment) Act, 2005 a daughter has also been given equal rights as son and she has also become a coparcener in the Hindu property and she has also got rights over the Hindu property to demand partition.
According to the Hindu Succession (Amendment) Act 2005, you have the same right over your father’s property as your brother. You have not mentioned whether the property is self-acquired or ancestral. In case of ancestral property, you have a right to it by virtue of birth and can make a claim over it. In case of self-acquired property, since your father died without a will, you will have an equal right to it as you are a class I heir along with your brother and mother. Hence, you can file a petition in the court seeking a right to the said property.
Thank You.
