Daughter right in ancestral property

You have to give more details, before one can give an appropriate answer to your query.  You have to give all the following information, without skipping any point/query.

1. How did your grandfather got the property? (i) did he purchase it or (ii) did he get it from his father?

2. In which year your grandfather die?

3. Whether the partition of the property was done by your grandfather when he was alive or after his death?

4. Whether your father is alive now?

5. If answer to query 4 is in the negative, then the date of death of your father. 

You have posted in query in 1st post itself, that your father got share in said land/property by partition suit from his father.

This implies court has partitioned the property.

Isn’t IT?

Your lawyer seems to be correct on nature of property partitioned by court of law.

Is IT your lawyer’s opinion that daughters (married) have NO share in Father’s self acquired property?

Is your father alive?

Succession opens on date/month/year of death of title holder/owner.

Has the mutation record been updated after said partition suit and do you have mutation recorded from beginning till date along with all link docs………..?

Who was 1st owner of said property amongst your ancestors..?

The property is not ancestral, but self -acquired. No one has any vested right or share in the property during lifetime.
