You say that this is ancestral proeprty, what is the basis?
Your grandfather's property cannot become ancestral proeprty hence basically there are no coparcenary rights.
In UP the daughters are not entitled to any share in the agricultural lands.
You say that your father distributed the lands between you and your brother, whether it was by a registered settlement deed or oral?
If oral then yo cannot claim ownership or title to the property.
Your father cannot be restricted to avail loan or mortgage or sell the property because it is his own and absolute proeprty until it has not been transferred to your name by a registered deed.
You confirm all the details and consult a local advocate on all such further issues to get appropriate relief and remedy
