If the property is in Scotland then it might be worth ensuring a slice of any land involved (such as a garden or similar) has not been claimed by an adjacent landowner. The original law on land registration (last two or three decades, not to be confused with the Sasines) was so badly framed that there are numerous examples of "errors" where, for example, the sale of a property has led to a unilaterally changed and registered boundary position with the loss of a slice by a neighbour. Even council land has passed into private hands this way. The law has recently or is about to change but the replacement was drawn up by the same parties as drew up and operated the old law. The outcome is or will be that the "errors" basically become irreversible and thereby the mess conveniently vanishes - but those who lose part of their property lose it permanently.
The known examples mostly came to light by chance, there are likely to be many more where the losers simply don't know what has happened because they have not needed to consult the position in the register (as for example you might now have occasion to do due to events).
