The wives of the Bali bombers want to say a final goodbye to their husbands before their executions.
Family members were denied a visit to the convicted men on Monday.
Lawyers claim this breached the condemned men's human rights.
Imam Samudra and brothers Amrozi and Mukhlas are due before a firing squad imminently.
They were convicted for their involvement in the nightclub bombings on 12 October, 2002, which killed 202 people including 88 Australians and three New Zealanders.
They have never expressed any remorse for Western victims of the attacks, but have previously expressed regret for the 68 Indonesians who died.
Ali Fauzi, the younger brother of Amrozi and Mukhlas told an online newspaper kompas.com, that the wives were eager to see their husbands.
Defence lawyer Achmad Michdan has flagged further legal action, following a fourth last-ditch request for a judicial appeal lodged in Bali on Monday.
However, Indonesia's Supreme Court said an eleventh-hour appeal would not delay their executions.
