Each member has an equal right to the property owned by an HUF. This means the said property cannot be sold without having each member of the family on board. New members that get added to the family by way of birth or marriage also have an equal share in the property.
In fact, even an unborn child, who is still in the womb of its mother, has a right to the property..
It must be noted here that once an HUF is formed it has to keep filing income tax returns until the time it is partitioned. When an HUF is dissolved, assets held by it are sold to be equally divided among all members. Now, each member will have to pay taxes on the profit thus made; the law perceives this gain as their individual income. Even if a new HUF is formed by married people who have exited the previous HUF, the income of the property would be taxed in the hands of new HUF..
