In those circumstances, the Civil Code provisions relating to the possession and the acquisition of property by adverse possession, even after the enactment of the Federal Constitution, are not in line with it, resulting in his irrelevance in rural acquisitive prescription.porAcesso AbertoPosse agráriaFunção social da terraUsucapião civil e usucapião agrárialand tenureSocial function of landCvil and agrarian acquisitive prescriptionArtigo10.5216/rfd.v38i2.33956
