My father purchased a flat in 1996 with his own earnings, he expired in 2007 without leaving a will. Who all will be legal heirs to this property.

The property left behind by your father will devolve on all the legal heirs i.e., you, your siblings and your mother.

One of the answers, mentions that my grand mother(father's mother) is also an heir. Could this be confirmed please? She was alive at the time of his death, but expired in 2013.

If your grandmother is not alive then she may not considered to be included in the legal heirship certificate after her death.

However if she has died before your father, then she is not entitled to any share in the property.
