Hi
1) In your case , as per amendment of hindu succession act in the year 1986 by Shri.N.T.Rama Rao, women in Andhra pradesh are entitled to share of ancestral property.
2) Also Supreme court has also said that Daughters are having equal right in an ancestral property subject to father being alive on September 9, 2005.
3) Now coming to self acquired property of your father, the defense you can put up before the court are
a) That the Ancestral property provided the seed capital for the father to acquire self acquired property and hence the self acquired property also acquired the nature of ancestral property and/or
b) The father under coercion, and undue influence of your brothers have executed the Gift deed in favour of the sons and / or
c) Father's health condition
4) Though points b and c might not be applicable in certain cases, it is still advised to put in to the draft of partition petition so that other side comes under pressure.
5) So, in order to stake your claim on above grounds you should file a partition suit in the CIVIL court and implead your father and brothers as other side.
6) Alternatively you can also approach the Lok adalat with pre-litigation petition and ask Lok adalat to resolve your grievance.
7) Lok adalat is preferred over CIVIL court as the process is cheaper, faster and does not break up sibling/parental relationships.
8) Also in Lok adalat, there is no mandatory court fees required to be paid where as in civil courts you need to pay 5% of value of your share of property as court fees.
9) Lok adalat is headed by District judges and lok adalat always encourages family reconciliation.
10) Lok adalat also favours women who has been excluded from their share of ancestral and self acquired properties of their parents.
Hope this information is useful.
