The two are accused of staging an elaborate hoax as a way of rustling up publicity.
A lawyer for Richard Heene says his client plans to plead guilty to a felony charge of attempting to influence a public servant. David Lane says Heene's wife Mayumi will plead guilty to a misdemeanor charge of false reporting.
The pleas are part of a deal to avoid possible deportation of Mayumi Heene to her native Japan.
Lane says Richard Heene is facing up to 90 days in jail and Mayumi up to 60.
Richard Heene has denied that the Oct. 15 event was a hoax. That day, the world watched as rescuers chased a homemade balloon believed to have the Heenes' 6-year-old son aboard. The Heenes later said the boy had been hiding at home.
Lane says Heene "feels like he's got to do what he's got to do to save his wife from being deported."
