The trial initially opened on October 19, where Saddam and seven-co-defendants faced charges including murder and torture in relation to a 1982 Shi'ite massacre.
The once-powerful Iraqi dictator and his co-defendants, who have all pleaded not guilty, face execution if convicted.
Defence lawyers are later expected to ask for a three-month delay of the trial as the team has not yet received some documents, according to Saddam lawyer Khames Hameed al-Ubaidi.
He said these include death certificates for the 148 people killed in Dujail.
Since the trial opening, two lawyers acting for Saddam co-defendants have been murdered, and Iraqi police on Saturday announced they had uncovered an al-Qaeda plot to assassinate the court's top investigative judge.
Police said they had arrested 12 members of a cell linked to the Iraqi branch of al-Qaeda in the northern city of Kirkuk who confessed to planning to kill judge Raed al-Juhi.
Saddam's Jordan-based defence team said several foreign lawyers, including former US attorney general Ramsey Clark, have travelled to Baghdad to attend the trial.
"Clark will challenge the court procedures and then call for the adjournment," Amman team member Ziad Najdawi told AFP.
There are also moves to add Mr Clark to the courtroom defence team.
A former attorney general under US President Lyndon Johnson, Mr Clark has recently acted as a civil rights attorney and activist and opposed the war in Iraq.
"Our plan is to go to court in Baghdad on Monday morning representing the defence counsel as defence support," Mr Clark told Reuters news agency before leaving Amman.
"A fair trial in this case is absolutely imperative for historical truth to justice obviously," he said.
The trial is taking place in a secret top-security courtroom in the heart of Baghdad's highly-fortified Green Zone, the first time an Arab leader has gone on trial for crimes committed against his own people.
The defendants include Barzan Ibrahim Hassan al-Tikriti, Saddam's half-brother and a former director of the feared Mukhabarat intelligence service, and former vice-president Taha Yassin Ramadan, one of the regime's 'enforcers'.
The defence team announced only last week that it would attend Monday's hearing, after boycotting all court procedures for the previous month in protest at the security arrangements for its Iraqi counsel.
US officials said most defence lawyers have now accepted the arrangements offered for their protection.
The defence team has been accused of playing for time in a bid to derail the trial, however judges are under international pressure to ensure that it goes ahead.
The session is expected to last for four days, with prosecution witnesses to be called to the stand, some testifying from behind screens or wearing face masks to protect their identity.
The charges relate to the killings of 148 men and youths from the Shi'ite village of Dujail, north of the capital, after the Saddam escaped an assassination attempt there in 1982.
About 200 villagers in Dujail, some holding pictures of victims of the massacre, staged a demonstration Monday calling for Saddam to face the death penalty.
Saddam, still feared by many in Iraq, could face other charges, ranging from the massacre of Kurds in 1988, a brutal crackdown against Shi'ites in 1991 and crimes committed during the wars against Iran and Kuwait.
Iraqi officials have said they chose to start with the Dujail case because it is relatively straightforward and well documented.
