A process which allows the legal estate to be conveyed/transferred free of some specific equitable rights which would otherwise continue to bind a purchaser of it. Can apply to the beneficial/equitable interest of a beneficiary under a trust of land. To overreach, some important technical requirements must be met. Put simply, where land is sold by trustees (plural) and the purchase money is paid to those trustees, the beneficial interest will no longer affect the land sold and will instead be in the purchase money.
