When two or more people agree to make a conjoint will, such testamentary documents are known as Joint Wills. These are generally created between married couples, with an intention to leave the property to their spouse after one of them dies. A joint will can also be created with an intention to take effect after the death of all the testators. In such Joint Wills till all the testators are alive, a single testator cannot revoke the will alone. He/ She would require the consent of other testators to revoke their joint will. Only when all other testators have died, the sole surviving testator can revoke the will alone.
