Or something like this:

The property was confiscated by the federal government when property taxes levied against Arlington estate were not paid in person by Mrs. Lee. The property was offered for public sale Jan. 11, 1864, and was purchased by a tax commissioner for "government use, for war, military, charitable and educational purposes."
Of course, that ended with this: George Washington Custis Lee brought an action for ejectment in the Circuit Court of Alexandria (today Arlington) County, Va. Custis Lee, as eldest son of Gen. and Mrs. Lee, claimed that the land had been illegally confiscated and that, according to his grandfather's will, he was the legal owner. In December 1882, the U.S. Supreme Court, in a 5-4 decision, returned the property to Custis Lee, stating that it had been confiscated without due process On March 3, 1883, Congress purchased the property from Lee for $150,000. It became a military reservation and Freedman's Village ceased to exist; however, the gravesites that were once part of the village remained on the grounds of the reservation.
But not all planters are going to do what Custis Lee did - neither his father or mother seem to have tried. Why, I'm not sure.
Either way, a lot of legal headaches, but probably easier than treason charges.
