1. In view of intestate death of your father, the Indian Succession Act of 1925 comes into play.

Therefore the assets ( land, apartment, jewellery, fixed deposits in Bank ) will devolve to his wife in the ratio of 1/3rd share and the remaining 2/3rd share will devolve to children of the decreased.  In other words, 1/3 × 100= 33.33% to your mother,  2/3 × 100=66.66% to all the children combined together, i.e., 16.66% each to 3 daughters and a son.

2.  If you are denied access to property documents, you can obtain certified copy of the Sale Deed from the jurisdictional Sub-registrar's Office, as also Encumbrance Certificate, wherein name of the owner, description of the property, transactions that have happened so far can be obtained.

3.  If you are denied your rightful share over the property, you can send a legal notice and if the matter is not resolved, then you can file for partition, declaration and separate possession of the property by metes and bounds.

Under The Indian Succession Act Where an intestate has left a widow and if he has left lineal descendants, that is, children 1/3 of his property shall belong to the widow, and the remaining 2/3 shall go to the lineal descendants.

One third will go to widow and two third to children.you can approach civil court if you are denied 

1. The 1/3 share will go to mother and rest will be equally divided between all children.

2. You can file partition suit for your share.

S. 33, S. 33-A, S. 34 of the Act govern succession to the widow. Together they lay down that if the deceased has left behind both a widow and lineal descendants, she will get one-third share in his estate while the remaining two-thirds will go to the latter. If no lineal descendants have been left but other kindred are alive, one-half of the estate passes to the widow and the rest to the kindred. And if no kindred are left either, the whole of the estate shall belong to his widow. Where, however, the intestate has left a widow but no lineal descendants, and the net value of his property does not exceed five thousand rupees, the whole of the property will go to the widow – but this provision does not apply to Indian Christians.. If the widow is still alive, the lineal descendants will take two-thirds of the estate. 

Till January 1986, Christians in the State of Kerala were governed by two different Acts - those domiciled in Cochin were subject to the application of the Cochin Christian Succession Act, 1921, while the Travancore Christians were governed by the Travancore Christian Succession Act, 1916. These two Acts have now been repealed and the Christians following these laws earlier are now governed by the general scheme of inheritance under the Indian Succession Act, 1925.

The law of intestate succession under S. 32 states that: The property of an intestate devolves upon the wife or husband or upon those who are of the kindred of the deceased, in the order and according to the rules.

S. 33, S. 33-A, S. 34 of the Act govern succession to the widow. Together they lay down that if the deceased has left behind both a widow and lineal descendants, she will get one-third share in his estate while the remaining two-thirds will go to the latter. If no lineal descendants have been left but other kindred are alive, one-half of the estate passes to the widow and the rest to the kindred. And if no kindred are left either, the whole of the estate shall belong to his widow

If the widow is still alive, the lineal descendants will take two-thirds of the estate; if not, they will take it in whole. Per capita (equal division of shares) applies if they stand in the same degree of relationship to the deceased. This is as per Sections 36-40 of the Act.

You can file a partition suit and claim your legitimate share in the property left behind by your father.
