not sure if this topic is in the right place but anyways

this query came up on the chisholm genealogy site and i was wondering if anyone could help out as my knowledge of old scots law is practically non-existent

ive copy and pasted this to avoid dilution of the query

Help needed with a bit of olde Scots Law, regarding feuing conditons.

Dictionary Definition follows:
Absolute interests in land
This means that a person has unfettered ownership of property, the equivalent of a freehold in English land law. In Scotland historically until the abolition of the feudal system there were two distinct legal estates, superiority and feu. The estate of superior was unfettered, and therefore absolute. Under a feudal estate the actual owner (or "feuar") must not have breached the feuing conditions, but he was otherwise entitled to complete possession of his property for all time, and therefore his ownership is also regarded as absolute, subject to any statutory restrictions, eg planning.

I know there was an old feudal custom (or is that condition?) that on the occasion of a marriage, the feudal superior retained an option to have first matrimonial rights with the lucky lady. I vaguely recollect this element may have been played up in some Hollywood rendition of olde Scotland. Does any forum reader have any idea if this custom continued into the relatively recent times of the early 1600's.
I am just asking this query with reference to Walter XIV of that ilk. If one disregards the Mckenzie story about being a Royalist soldier captured at Preston in 1648, one can find a story more salacious in nature, in which young Walter incurs the great wrath of his feudal superior, Douglas of Drumlanrig. The story goes that Drumlanrig did not approve of Walters choice of woman, and fined him 5,000 merks, enough to cause the loss of the Chisholme Estate. Would anyone know if ancient feuing conditions also included the right of the Superior to approve the marriage partner of his "feuar"?
