my father had a total property of 494 sq yards. we are two brothers and four sisters. my father passed away in 2018
1. he gave 165 sq yards to his elder son. elder son have registered his property in his name
2. he gave 204 sq yard to his younger son (myself) through a stamped Will. but the property found out to be 186 sq yards.
3. the property adjacent to my property is the third property on which a will has been made in the name of all the siblings. the property is 143 sq yards but in Will it is written 125 sq yards.
referring to point 2 and 3 my 18 yards ( 204-186 ) has gone in the 3rd property ( 143-125 ).
now I being the younger son is demanding back my 18 sq yards but all the siblings are not in consent with me and instead they are threatening that they will go legal and will take share in my property too because it is still not registered in my name.
question1: can they challenge my will ?
question 2 : can a stamped will by my father be proved fraudulent. one of the witness in my will is my brother in law ( my sister husband )
question 3 should I go for registration of my property in my name
