Wills and Probate in UK Law

If judges were too ready to accept such contentions, it would risk undermining what may be regarded as a fundamental principle of English law, namely that people should in general be free to leave their property as they choose, and it would run the danger of encouraging people to contest wills, which could result in many estates being diminished by substantial legal costs.

It is then the duty of the Court by the exercise of its judicial knowledge and experience in the relevant matter, innate commonsense and desire to make sense of the settlor's or parties' expressed intentions, however obscure and ambiguous the language that may have been used, to give a reasonable meaning to that language if it can do so without doing complete violence to it.

Moreover the fundamental principle that equity is concerned to prevent unconscionable conduct permeates all the elements of the doctrine.

When it comes to interpreting wills, it seems to me that the approach should be the same.

However, there is now a highly relevant statutory provision relating to the interpretation of wills, namely section 21 of the 1982 Act ("section 21"). Section 21 is headed "Interpretation of wills — general rules as to evidence", and is in the following terms:
