The Magna Carta, sealed under oath by King John at Runnymede, England in 1215, became part of English law, and subsequently adopted into Australian law.
To see the contents of a deceased person’s will can be difficult. But in some states if you know who has the will, a copy, or other testamentary document, the law requires them to allow certain categories of people who are entitled under the law, to have access. If you are within one of these categories you are entitled to inspect or see the will; and obtain a copy of it. Copying is at your expense, but the costs must be reasonable.
