The fifth division of the anti-graft court also ordered the former first lady to explain in 30 days why she was absent during the promulgation on Friday or face arrest.
Marcos, 89, faces imprisonment of between six and 11 years for each count of graft, according to the Sandiganbayan decision released to media today.
Neither Marcos nor anyone representing her attended Friday's court hearing.
Marcos can also raise the decision to the Supreme Court if she finds grave abuse of discretion on the part of the Sandiganbayan.
The charges, filed in the 1990s, stem from companies set up by the family in Switzerland prior to her husband's ouster in 1986, CNN Philippines says.
Marcos said in a statement that the decision was being studied by one of her lawyers who notified the Marcos family that he intends to appeal the decision. The Marcoses have been accused of plundering the government's coffers amid crushing poverty.
