[IDEM libro quinto responsorum. ] §20.1.29.prPaulus respondit generalem quidem conuentionem sufficere ad obligationem pignorum: sed ea, quae ex bonis defuncti non fuerunt, sed postea ab herede eius ex alia causa adquisita sunt, uindicari non posse a creditore testatoris.
[BY THE SAME AUTHOR, in his fifth book of Opinions.] Paulus answered that a general agreement is indeed sufficient for the obligation of pledges; but those things which did not belong to the property of the deceased, but were afterwards acquired by his heir from another cause, cannot be claimed by the creditor of the testator.
§20.1.29.1Si mancipia in causam pignoris ceciderunt, ea quoque, quae ex his nata sunt, eodem iure habenda sunt.
If slaves have fallen into the condition of a pledge, those also who are born from them must be held under the same right.
quod tamen diximus etiam adgnata teneri, siue specialiter de his conuenerit siue non, ita procedit, si dominium eorum ad eum peruenit qui obligauit uel heredem eius: ceterum si apud alium dominum pepererint, non erunt obligata.
However, our statement that even those born afterwards are bound, whether there has been a special agreement concerning them or not, applies only if their ownership has come to the person who pledged them or to his heir; but if they were born under another owner, they will not be bound.
§20.1.29.2Domus pignori data exusta est eamque aream emit Lucius Titius et exstruxit: quaesitum est de iure pignoris.
A house given in pledge was burned down, and Lucius Titius bought the ground and built upon it; a question arose concerning the right of pledge.
Paulus respondit pignoris persecutionem perseuerare et ideo ius soli superficiem secutam uideri, id est cum iure pignoris: sed bona fide possessores non aliter cogendos creditoribus aedificium restituere, quam sumptus in exstructione erogatos, quatenus pretiosior res facta est, reciperent.
Paulus answered that the pursuit of the pledge continues, and therefore the building is deemed to follow the right of the ground, that is, together with the right of pledge; but bona fide possessors ought not to be compelled to restore the building to the creditors otherwise than if they receive the expenses incurred in the building, to the extent that the property has been made more valuable.
§20.1.29.3Si sciente et consentiente domino seruus, ut omnia bona domini pignori obligata essent, conuenit, ipsum quoque qui cauit obligatum esse pignoris iure.
If, with the knowledge and consent of his master, a slave agreed that all the property of his master should be obligated in pledge, the slave himself who made the agreement is also obligated by the right of pledge.
