Can i ask for my property

 You,  along with your brother,  sister and mother are legal heirs of your father. All of you have equal share in your father's property.  If you want your share seperated,  you can file a suit for partition and seperate possession. 

 Adv  ARCHANA is right.

 Your mother alone could not have become a sole legal heir, unless she was the joint-holder of the property. You will have access to the records of the revenue department where the legal heir certificate if any was obtained by your mother. It should contain your name also as one of the legal heir and without your no objection/consent, your mother alone  could not have become the sole heir. Hence before filing any suit as advised by my colleague members, it would be prudent to check the complete details. This will help you determining the appropriate civil/criminal proceedings. Based on the documents, you will even be in a better position to strike a compromise deal as civil proceedingswould take a long time besides considerable expense..Vasudevan

If your father has died intestate then no more documents needed to file a suit for partition. The revenue records does not prove title in property though it helps the court in making presumption.
