For security reasons he has been held at his lavish estate on the suburbs of Islamabad instead of a jail.
Pakistani security forces have been protecting the estate following threats he received from the Taliban upon his return.
Musharraf is reviled by the militants because he launched a series of attacks against their bases in the tribal areas near Afghanistan and for ordering a raid against a hard-line mosque in Islamabad in 2007.
Police are also investigating his role in the operation against the mosque that killed nearly 100 people.
