self acquired property

whether the above land is self acquired property of  my father?

 NO

If not whether my sisters are eligible for equal partition in the land. Because since from 1987 i am cultivating the above .

 YES

During 1986-87 my father transfered his property on my and my brother name by the process of mutation registeration which was done by reveue inspector and tahsildar.

Am  I an absolute owner of above land after long period of 20 years. ?                                            NO                  

Since no arrangement for partition in the property and the same is done only oral and mutation also done accordingly. 

Property is not self acquired by your father as the same is divided by your grand father.

Since the property is not registered, your sister/sisters, if they prefer to sue you, then they need to initiate suit for partition against all the living legal heirs of your grand father.

The revenue authorities can mutate the land based on the memorandum of family arrangement submitted by the co-sharers. The said famly arrangment deed must  be executed in persuance of the earlier oral partition. In such case the deed of family arrangement supported by the oral partion amounts to valid partiton. and  in such case the property acquired by your father will be treated as self acquired property. Further as the partition(i.,e oral partition supported by family arrangement deed)  between you and your brother was affected well before 2005, your sisters are entitled to any share. But you need to prove the said oral partition.

Kindly define self acquired property in legal terminology
