Sons Right In Father Property

बड़े भाई को दादाजी की सम्पत्ति से हिस्सा लेने के लिए उन्हें दादाजी मनना होगा। other wise not possible.

yadi property aapke grandfather ne khud kamayi hai toh bada beta apna ansh nhi maang sakta ya phir agar property purkho ki hai toh apna ansh maang sakte hai.

if self aquired property elder son has no right... if property is hindujoint family or ancistorial property elder son has right over the property

No

its your grandfather earned property he can gift anyone as he desired. now elder cannot sue in court there are very less chances to succeed

gift deed diya hai?
