[ULPIANUS libro duodecimo ad edictum. ] §42.4.1.prTres fere causae sunt, ex quibus in possessionem mitti solet: rei seruandae causa, item legatorum seruandorum gratia et uentris nomine.
[ULPIAN in the twelfth book on the Edict.] There are roughly three causes for which a placing in possession is customary: for the purpose of preserving property, likewise for the sake of preserving legacies, and on behalf of the unborn child.
damni enim infecti nomine si non cauetur, non in uniuersorum nomine fit missio, sed rei tantum, de qua damnum timetur.
For if security is not given on account of threatened damage, the placing in possession is not made in the name of the entirety of the property, but only of the specific thing concerning which damage is feared.
