以上單詞均有將某人驅(qū)逐出不動(dòng)產(chǎn)之外的含義。ejectment 為“驅(qū)逐非法占有人之訴”，主要指普通法所規(guī)定的一訴訟，原告目的是驅(qū)逐土地或建筑物的不法占有人且主張得到損害賠償金，即將不法占有人驅(qū)逐而恢復(fù)自己的合法權(quán)益?，F(xiàn)在，ejectment 已經(jīng)逐漸演變成純粹的就不動(dòng)產(chǎn)產(chǎn)權(quán)進(jìn)行爭(zhēng)議的訴訟[1]。ouster則剛好相反，多指非法將某人從其合法占有的不動(dòng)產(chǎn)中驅(qū)逐出去而達(dá)到非法占有的目的，故其為“非法驅(qū)逐他人而強(qiáng)占 財(cái)產(chǎn)”，其為一過(guò)錯(cuò)行為（wrong) [2]。eviction多指對(duì)房客或佃戶的驅(qū)逐，其可為合法驅(qū)逐，特別是依法向法院提起訴訟；也可指非法驅(qū)逐，如非法入侵者驅(qū)逐合法所有人或房東或地主違法將租戶或佃戶驅(qū)逐[3]。
