What a plan usually involves
Documents that agree with each other, reviewed as things change.
For a business with more than one owner, the centrepiece is usually a shareholders or partnership agreement containing buy-sell provisions: what happens on death, disability or a falling out, how the exiting owner's interest is valued, and where the money comes from, which is often insurance held for exactly that purpose.
Around it sit the constitution or trust deed, the succession of trustee and appointor roles, binding death benefit nominations for super, and a will and enduring power of attorney that do not contradict any of it. For a family business there is usually a harder conversation as well, about the child who works in the business and the ones who do not, and how to be fair without being equal. We will help you have it, and then document what you decide.
