The Larimer and Jackson, Colo. county District Attorney offices formally filed charges Thursday.
Mayumi Heene will plead guilty to falsely reporting to authorities, a misdemeanor. Richard Heene's charge - attempting to influence a public official - is a felony. The deal stipulates a probation sentence for both charges.
The deal avoids more serious felony charges against Mayumi Heene, such as perjury, that could result in her deportation to Japan.
According to the DA office's release, Mayumi Heene could face six months in county jail and a fine of $50 to $750. The penalty for Richard Heene could be 2-to-6 years in prison and a fine of $2,000 to $500,000.
"Upon reviewing the evidence, arguably, Mayumi could have possibly ended up being deported and Richard could have proceeded to trial and had a good chance at an acquittal," lawyer David Lane said. "This, however, would have put the family at grave risk of seeing a loving, caring, compassionate wife and mother ripped from the family and deported. That was not an acceptable risk, thus these pleas."
CBS News legal analyst Andrew Cohen said the deal "makes sense for both sides, especially given the cost of a trial and the risk that the mother involved here would have been deported and separated from her children. So I'm not surprised at all that this ends with a whimper and not a bang."
Cohen notes the judge doesn't have to accept the plea deal and could alter its terms.
