a brother can file a suit for pre-emption against his other brother for property
A person can claim pre-emption if they have a certain relationship to the seller of the property, and if they meet other requirements. For example, in Mahomedan law, a co-sharer in the property or a participator in immunities and appendages can claim pre-emption.
The right of pre-emption must exist on the date of registration of the sale-deed, the date of filing the suit, and the date the court decrees the case
In terms of the Constitution Bench judgment of this Court in Shyam Sunder and others v. Ram Kumar and another, the right of pre-emption has to exist on the date of registration of the sale-deed, on the date of filing of suit and also on the date the same is decreed by the first Court.
The right of pre-emption is the right to offer the property to be sold. It is the inherent right or the primary right of the adjacent property's owner. It is the remedial right of the pre-emptor to follow the thing sold.
