Wills, Family Trusts, and Power of Attorney
If you are concerned about protecting your money, property and investments then you need to put in place some form of asset protection like a will or family trust. It may be prudent to have both.
Wills and Estates
Unless you have a Will, your assets will be distributed to family members according to New Zealand's law governing intestate estates - and the distribution may not be in accordance with your wishes.
Power of Attorney and Enduring Power of Attorney
A general Power of Attorney is an authority you give to someone to handle your property affairs while you are mentally capable. It is common, for instance, for this to be arranged if you are intending to travel overseas.
