Smith's farm was seized under Zimbabwe's land-reform program, which takes white-owned land and redistributes it among black farmers, the BBC reported.
Smith lived at the farm, called Gwenoro, during most of his adult life, and after he died in 2007, his ashes were scattered there.
The seizure came as President Robert Mugabe addressed supporters ahead of elections in 2013. Mugabe, 88, is running for another term.
