The Supreme Court has held that a family settlement document which merely sets out the existing arrangement and past transaction will not be compulsorily registrable under Section 17(1)(b) of the Registration Act, 1908, if it doesn't by itself creates, declares, limits or extinguishes rights in the immovable properties.
Therefore, such a document will not be hit by the bar under Section 49 of the Registration Act.
