A family with a mother, her children(2 daughters and 4 sons).
One of the daughter has taken the amount and given the release deed.
The release deed doesnt have the name/presence of the "other" daughter anywhere in the document.
Without the "other" daughter's concern the sons have re-constructed house(s) on those properties.
In the release deed , a statement which mentions about 2 wills made by their deceased father.
Out of those, only one will document (duplicate copy of its un-registered form) was sent to the "other" daughter after so many years of the father's death.
The other will document was not even shown still.
Their father had mentioned about his health state in the will, and he wrote it before his death.
*** Now, is the release document and the construction of house legally accepted?
Thanks in advance
