Is it permissible to give Zakat to a indebted brother who is unable to repay?

It is permissible to give Zakat to an indebted brother who is unable to pay his debt, provided that his debt was incurred for a permissible matter, such as building a house. An indebted brother is more deserving of charity than others, for giving him charity is both an act of charity and an act of maintaining kinship ties.
