Newly elected president Mohammed Morsi will take the oath of office on Saturday before Egypt's highest court, state television reported online.
The move ends controversy over where the new leader is to be sworn in, dpa reported.
"It has been agreed that the president-elect will take the oath before the general assembly of the Supreme Constitutional Court," said Maher Sami, the court's deputy chief.
A ruling earlier this month by the same court invalidating the Islamist-dominated parliament had incensed Morsi's Muslim Brotherhood and prompted its supporters to demand the president-elect take the oath either before the dissolved legislature or in Tahrir Square, a focal point for protests that toppled Hosny Mubarak in February 2011.
Under a temporary constitution issued by the military rulers, the new president is obliged to be sworn in before the court.
Islamists and anti-military activists have accused the generals of tightening their grip on power by granting themselves sweeping authority in the temporary constitution.
"The court has not received information or applications for deputies of the (dissolved) legislature to attend the swearing-in ceremony," Sami said.
The military, which took after Mubarak, has repeatedly pledged to hand over power to the elected president by June 30.
Meanwhile, Mursi, Egypt's first elected civilian president, is to address a rally Friday in Tahrir, state television reported online, citing Mursi's spokesman.
Thousands of activists, mainly Islamists, have been camped in Tahrir for more than a week, demanding the military abolish the controversial temporary constitution and reinstate parliament.
