“By contract of marriage the lands being provided to the heir by the first clause, and the conquest to the bairns in a subsequent clause, the lords found the heir had a share in the conquest (though it was most part executry), without collation, because he was also a bairn.” (Brown, July 21, 1680, Mor. 2375.) In that case collation was excluded, not because the heir had a jus crediti to the lands under the marriage contract, which, if the appellant's argument were well founded, would of itself have been conclusive, but on a totally different ground, namely, that by another clause of the contract the father had bound himself to give the children, and therefore the heir, being one of the children, the conquest of the marriage, which was chiefly moveable. A father has at all times the power of excluding collation; but he does so by conveying to the heirashare of the moveables, which, unless so conveyed, would have gone to the executors; and it is plain from the ratio decidendi that if the father had left personal estate which was not conquest of the marriage, and therefore not falling under the second clause of the contract, the heir could not have claimed a share of it without collating his lands. Thus, it appears that a jus crediti in an heir (even although it be not acquired by gift, but for an onerous consideration,) to succeed to his predecessor's heritable estate, does not relieve him from the obligation to collate; nor is he relieved though the predecessor, in fulfilment of his obligation, chooses to propel the succession by a deed inter vivos. It has been said that the heir is not bound to collate a fee strictly entailed, because he cannot alienate the lands to the executors without the risk of incurring an irritancy. If it were so, the consequence would be, as is well laid down in the Little Gilmour case, that he would never get a share of the personal property at all, because he could not comply with the condition under which exclusively he is entitled to that share. But it is undoubted law that the heir collating is not bound to convey to the executors an absolute fee. He must share the heritage with them, subject to all the burdens under which he himself has taken it. There is nothing to prevent him to convey to them a right to the lands or to their produce, defeasible in the event of his own death, or of a decree of irritancy being obtained against him. This is no contravention, if the decision in the case of Nairne , (Feb. 15, 1810,) and the ordinary practice of the Court in dealing with entailed succession, can be relied upon. If not, certainly there is no impediment to his sharing the produce Page: 534 ↓ of the tailzied estate with the executors; and if they consent to hold that as collation, it is enough. It is a case a fortiori in their favour, that he is not able to pay all the price which ordinarily they receive for a communication of their right to the moveable succession. We are of opinion, therefore, that the general principles of the law of Scotland afford no ground for holding a fee limited by strict tailzie, more than any other limited fee, to be exempted from collation, or for supposing that it forms an exception to the rule laid down by the institutional writers, in absolute terms, as applicable to all heritage whatever in the person of the defunct, descending to the heir alioqui successurus. Neither do the decisions of this Court, or of the House of Lords, exhibit a trace of evidence that such an exception was ever recognized. The cases of Murray and of Brown , on the contrary, as we have just seen, negative the plea that heritage, because it is taken in virtue of a deed of provision, or because the heir who takes it has a jus crediti to the succession, is exempted from the rule. The case of Scotstarvit shows that lands holden under a special destination or tailzie fall under it. And in the case of Rae Crauford (Dec. 3, 1794), where the estate was strictly entailed, it follows, by plain inference from the interlocutor of the Court, that if the lady had been heir of line, which she was not, but only heir of provision, which by itself imposed no such obligation, she would have been bound to collate. That neither the case of Rickarts nor that of Scotstarvit can afford aid to the appellant is, in our opinion, sufficiently obvious. In the former, it was impossible that there could be collation, because the succession did not divide into separate channels. All the daughters were heirs at law, and all of them were executors. The fundamental principle of the law of collation is, that the heir who is excluded from the moveables shall purchase a share of them by throwing the heritage into the common fund. But in the case of heirs portioners, each, dejure, has a share of the moveables, and therefore the eldest has no occasion to purchase that right. And this was only a repetition of the judgment pronounced in the case of Jack many years before, where the Lords found that there was no collation to be made by the law of Scotland but only in the case of moveables, which, according to Gosford's report, was looked upon “as a constitute custom, without all controversy or debate.”
