Making a Will is important but it is not the end of the process it is actually the start.
If you make your Will today, hopefully, you are not going to die today. Your plan is to push that date to a long time into the future. That means, with good fortune, there is a long period between today and when you die. It means you can spend time thinking about living, not death.
Whilst you live, you can reflect not on who gets what when you die, but what are the consequences. This is where an Estate and Succession Plan is vital.
