I have looked into the matter. First, the Faculty of Advocates, in our response a year ago, supported that narrow provision—if I can style it as such—and I would seek to be consistent in that respect.
In 1990, as Mr Kerrigan suggested, the Scottish Law Commission articulated concern about the fact that people may have made statements to relatives but not been totally frank or may have changed their mind. The time at which they make their testamentary provision is the time at which the intention matters.
The Scottish Law Commission was persuaded to restrict its recommendation to the narrow type of measure because of the difficulties of comparing what is in the will with what is supposedly other evidence about a different intention.
There is an interesting interplay in any such law between rectification and interpretation. It is sometimes said that, if there is a wide door for rectification, there is only a narrow door for interpretation. There being a narrow door for rectification, it may be that the courts would take a more generous approach to interpretation.
I accept that this is speculation, but, if somebody has made a mess of a will that they have made themselves, the courts might be prepared to be more generous in interpretation if it was reasonably clear what the testator was trying to do.
I do not want to advance a position any different from the Law Commission’s recommendation that the provision on rectification should be confined to quite a narrow scenario. I note that it appears to be the position that a fairly narrow rectification provision operates in England as well.
