Circuit Judge Stan Strickland sentenced Anthony to time served in jail, as well as probation if she is ever released. She remains jailed on a charge of first-degree murder in the death of her 2-year-old daughter, Caylee.
Anthony has pleaded not guilty in the slaying. She says a baby sitter kidnapped Caylee, whose body was found near the Anthonys' Orlando home after a months-long search.
Prosecutors had asked for five years in prison for the check fraud charges.
They are seeking the death penalty in Caylee's slaying.
