After the father's death, we inherited his shop (a rented poultry shop). The landlord wanted to reclaim the shop as it was causing discomfort. The owner appointed a lawyer, and after much back and forth, the owner decided to register the shop in the name of one of the brothers, out of compassion for the minor sister who is 4 years old. Now, the remaining siblings, upon learning that the shop is in this brother's name, became angry and threatened him. What is the ruling regarding the brother who registered the shop in his name, without consulting the others, whether he did it to preserve the shop because the landlord was insistent on taking it back or for any other intention?
