Is a flat purchased by selling inherited flat self acquired?

Who has invested money to purchase property

Person B has bought the flat.

Person B was joint holder in the previous property and after the death of her husband became the sole owner of the property. She then sold that property and bought the current property from the sale proceeds.

My question is, can she gift this property or will it to her son or dose she have to divide it between the 2 children.

Thank you

I would also like to know if once you inherit a property and then sell it, when you buy a home would that count as self acquired?

Thank you

It becomes the own property of B since prior to that the sons have relinquished their rights in the property that was sold by her as an absolute owner.

Thus she becomes an absolute owner of the property now purchased if it was on her name alone, whereas she has purchased on joint names, hence it will be considered as joint property

Thank you for your help. Can Person B now gift her share of the property to her son wth whom she is the joint holder. And if she does so, can the other child contest the gift deed. Thank you

She can very well dispose her own share in the property now jointly held,  to the other joint owner.

There is no legal infirmity in it.

Any dispuite in this by a third person is not maintainable in law.
