Trusts can be structured in several ways to protect your assets. For example, placing your assets in a trust puts them outside the reach of creditors or claims of liability that might be brought against you.
Trusts can also reduce your tax liability by being designed to reduce the amount of taxes you personally have to pay.
Putting your assets in a trust can also put them outside the reach of the government. Should you need governmental assistance for long-term care- perhaps as you age or suffer a disability- placing your assets in a trust can ensure that those assets will not be depleted because of your need.
