Hello, Greetings of the day!
The will here clearly states that both the brothers are eligible for equal shares of the property and one person cannot sell the property without the consent of the other. In the case of disagreement where the person wants to sell the property and the other is not willing to do so, one of the remedies can be that person unwilling to sell the property buys the share of the property from the other party who wants to sell the party.
Another option can be that brother unwilling to sell the property, can file a suit of the partition before a civil court can apply for an injunction order on the sale of the property. If the disagreement still exists among the parties, then either of the party can apply for a gift deed or a relinquishment deed in the favour of the opposition party.
