Firstly, can a will be broken? What needs to be the case, if it can be broken? Secondly, my wife's grandfather had a property and he made a will which stated that the property should be shared only between 2 children out of the 5. He promised agricultural lands to the other 3 children. But the will states that the three children will receive a sum of one lakh rupees from the 2 children who got the property. Now, one of them has claimed the money. Are there any chances that the other two would ask for equal share in the property?
The question is vague. However, a testator can change his will as many times as he wants and only the last will made by the testator will have any relevance.
