A person (called a testator or testatrix) leaves a will when they make a written declaration about what they want done with their property and assets (called their estate) after their death.
Your will does not have to just deal with your estate. It can include other wishes like who will look after your children until they reach 18, and whether you like to set up trusts to benefit certain people in your life.
Many people have already done a will at some point in their life, whether on their own or with the help of a professional. However, not many people are aware that whilst the legal requirements of a valid will are simple under the Succession Act 2006 (NSW), these requirements can easily be overlooked or challenged by others after their death leaving their estate subject to family disputes and legal battles. Your will should also include a revocation clause to clearly indicate that you want your will to operate as your final testamentary wishes. This removes doubt on any old documents that may also be considered a will or an informal will.
Regardless of your age, If you have any assets and want to make sure that those assets are dealt with in a particular way, it is important that you speak to a lawyer who specialises in Estate Planning and get them to prepare a professionally drafted will.
