Later, Grandfather died in 1988 intestate. Grandmother took hold of property and registered one floor of 3 floor building to her daughter. Father is not a party to this deed. Whether this a valid document in the eyes of law. If not, can we get this transaction nullified?
In my opinion this property is the the one retained by the grandfather for his and his wife's personal use.
If the property still remained in his own name as on the date of his death, then the property shall devolve equally on all his legal heirs consisting his wife, son and daughters.
Thus she has no rights to transfer any share in this property to a daughter of her choice without all other heirs consenting or expressing their no objection this.
This can be termed as deprivation of their rights in the property, hence invalid and not binding on them.
Instead of filing a cancellation deed, the other heirs can file a partition suit seeking partition and separate possession their respective share in it.
Grandmother and father died this year. All died intestate. Whether my daughter in law will be sole owner of this property as my grandfather died in 1988 itself I.e., before 2005?
The position of law is that the property retained by her grandfather, upon his intestate death devolved equally on all legal heirs consisting his wife, son and three daughters.
Now the share of your daughter in law's father shall devolve equally on his own legal heirs consisting his wife, and children.
Therefore she can claim her own share out of her father's share in the property which are to be divided among the 3 daughters and one son.
