You may also wish to consider signing Enduring Powers of Attorney (EPOA). These are very useful in the unlikely event that you become incapacitated (for example a stroke can occur at any age) or ill or are overseas and needing someone to act for you. These EPOA documents can be for both property and important care/welfare decisions.
No one knows what the future holds and it can be very expensive for your family to obtain a court order to appoint a manager for your affairs. It is better that you provide for this now. For further information click on this link (“Enduring Powers of Attorney”)
