MICHAEL Weir raises some interesting points in his letter on superiorities (May 1).

When the Land Tenure Reform (Scotland) Act, 1974, was passed, it was generally thought that superiorities would ''die on the vine,'' since the Act prohibited the creation of any new feu-duties and provided for compulsory redemption of an allocated feu-duty when a property was sold.

Unfortunately, those of us involved in conveyancing have helped to breathe new life into the feudal system by insisting on the superior's consent for even the most trivial of alterations, such as installation of double glazing or central heating.

It was not always so. I remember a friend being puzzled about 15 years ago because his parents' solicitors were insisting that retrospective superior's consent had to be purchased for an extension to their home which had been built in the 1930s, despite the property having been sold on a number of occasions since then.

Whereas in the past conveyancers were inclined to the view that a superior who was collecting feu-duties could be held to have acquiesced in alterations about which he had raised no objections, they are now inclined to insist on evidence of consent to any alteration, even though the superior now no longer has any continuing interest in the property.

This is somewhat perverse since the Conveyancing and Feudal Reform (Scotland) Act, 1970, allows a proprietor to apply to the Lands Tribunal for the variation or discharge of any obligation which impedes some reasonable use of his property.

The problem could be resolved by changing the law to provide that a superior shall be presumed to have acquiesced in alterations. To rebut this presumption the superior would have to show that he had an interest over and over his mere title, in enforcing the feuing obligations.

This would protect those feu superiors who do have a genuine interest in a property and at the same time sweep away a great deal of time-consuming and expensive bureaucracy.
