5 However, as the instituted heirs, when (as so often was the case) they were requested to transfer the whole or nearly the whole of an inheritance, declined to accept for what was no benefit, or at most a very slight benefit, to themselves, and this caused a failure of the trusts, afterwards, in the time of the Emperor Vespasian, and during the consulate of Pegasus and Pusio, the senate decreed that an heir who was requested to transfer the inheritance should have the same right to retain a fourth thereof as the lex Falcidia gives to an heir charged with the payment of legacies, and gave a similar right of retaining the fourth of any specific thing left in trust. After the passing of this senatusconsult the heir, wherever it came into operation, was sole administrator, and the transferee of the residue was in the position of a partiary legatee, that is, of a legatee of a certain specified portion of the estate under the kind of bequest called participation, so that the stipulations which had been usual between an heir and a partiary legatee were now entered into by the heir and transferee, in order to secure a rateable division of the gains and losses arising out of the inheritance. 6 Accordingly, after this, if no more than threefourths of the inheritance was in trust to be transferred, then the SC. Trebellianum governed the transfer, and both were liable to be sued for the debts of the inheritance in rateable portions, the heir by civil law, the transferee, as quasiheir, by that enactment. But if more than threefourths, or even the whole was left in trust to be transferred, the SC. Pegasianum came into operation, and when once the heir had accepted, of course voluntarily, he was the sole administrator whether he retained onefourth or declined to retain it: but if he did, he entered into stipulations with the transferee similar to those usual between the heir and a partiary legatee, while if he did not, but transferred the whole inheritance, he covenanted with him as quasi-purchaser. If an instituted heir refuse to accept an inheritance from a suspicion that the liabilities exceed the assets, it is provided by the SC. Pegasianum that, on the petition of the person to whom he is requested to transfer, he shall be ordered by the praetor to accept and transfer it, whereupon the transferee shall be as capable of suing and being sued as the transferee under the SC. Trebellianum. In this case no stipulations are necessary, because by a concurrent operation of the two senatusconsults both the transferor is protected, and all actions relating to the inheritance pass to and against the transferee.
