The wealthy use asset protection to stop would be thieves from taking their money.
In Australia the most popular form of wealth preservation is by using a “Family Discretionary Trust” (FDT). In order to use this type of structure you need to understand the terms before commencing creating and finally using trusts. They are a form of business that has significant advantages beyond a normal company structure. The benefits include asset protection, and tax advantages.
Yes they are more complex, and expensive to run, the corporate compliance and ASIC rules are more complex, but you cannot get asset protection AFTER you are hit with a lawsuit. It must be established and operational well before time, furthermore the lawsuit can come from anywhere, anytime.
To prepare yourself, and before you engage any lawyer or accountant (that charges by the hour), spend some time to learn the language they will talk to you in.
