It became customary towards the close of the sixteenth century for security to be given, with the notice of banns, for the solemnisation of the marriage, two friends of the parties depositing with the clerk a sum of money as a guarantee, and that for more than one purpose. In 1570 the Assembly ordered that "promise of marriage shall be made according to the order of the reformed Kirk to the minister, exhorter, or reader, taking caution for abstinence till the marriage be solemnised." The minutes of Kirk Sessions show that, in numerous instances, during the latter half of the seventeenth century, such deposits were retained for the space of nine calendar months after the marriage. The Kilmarnock Kirk Session was not so strict. It was there ordered, in 1670, that the deposit should be returned to the parties on the expiration of half a year. Whatever the term was, if scandal arose before it expired, the deposit became forfeited. Kirk Sessions in some cases accepted personal security in lieu of cash, the bondsmen in such cases becoming liable in the event of scandal arising, or the non-solemnisation of the marriage. But this system, so convenient for those who could not raise the caution money, or "pawn," as it was commonly called, was in course of time abandoned. The Kirk Session of Mauchline instructed the clerk, in 1691, "to take neither bond nor cautioner for consignation money, but to require that the money be laid down, to remain in his hand for the space of three-quarters of a year." The example was followed by other Kirk Sessions, but the custom continued for a long time afterwards, and was never formally abolished, falling into abeyance gradually. Dr Edgar, in his "Old Church Life in Scotland," states that "on a page at the end of a small volume of scroll minutes still extant there is a writing, under date 23rd November, 1771, which has all the appearance of being a genuine matrimonial consignation bond." The First Book of Discipline makes it peremptory that no persons should be married without the consent of the parents, unless it should appear that there was no reasonable ground for the refusal of their consent. The Westminster Directory qualifies this by ruling that the consent of parents should be obtained to first marriages, especially if the parties were under age. It is not clear whether non-age means under the age of twenty-one, or is to be interpreted by the decree of the General Assembly of 1600 that, "considering that there is no statute of the kirk,... defining the age of persons which are to be married, ordain that no minister within this realm presume to join in matrimony any persons in time coming, except the man be fourteen years of age, and the woman twelve complete." The same ages are given in the First Book of Discipline.
