A Muslim family's sisters discovered that their handicapped brother, A, was misled into signing away land registration in favour of X in 2019. This land was subsequently sold twice more, first to Y in 2019 and then to Z in 2020. The sisters, who care for their brother, are now seeking advice on whether they can file a suit to cancel these multiple registered sale deeds due to misrepresentation. They are also inquiring about the court fees required for such a legal challenge.
