Start by answering the following questions:
Who? Who do you want to benefit from your wealth? What do you need to provide for your spouse? Should your children share equally in your estate – does one or more have special needs? Do you wish to include grandchildren? Would you like to give to charity?
What? Should your business pass only to those children who have become involved in the business, and should you compensate the others with assets of comparable value? Consider the implications and complications of multiple ownership.
When? Consider the age and maturity of your beneficiaries. Should assets be placed into a trust restricting access to income and/or capital? Or should gifts wait until your death?
