Family-owned farms constitute a fundamental unit of Polish agricultural structure. However, it is necessary to improve the area structure of Polish agriculture. It is supposed to be achieved with the help of the Agricultural Structure Management Act of 11.04.2003 which introduces certain restrictions in agricultural real-property trade. The responsibilities include a duty to inform the Agricultural Property Agency on concluding contracts of right transfer of these real-properties. The Agency has the right to dissolve the contract and purchase the agricultural real-property for the Treasury paying less for the property than its value estimated by the contracting parties.
