By making a Will, you are simply ensuring that your final wishes are legally recognised.
More importantly though, writing a last Will and testament gives you the certainty and peace of mind from knowing that your property and possessions (also known as your estate) can be passed on exactly as you want on your death.
Without a Will, the state decides who gets what from your belongings and how much, so those who you would want to benefit may get far less than you hoped. Like most people, you might assume that your property would automatically go to your spouse and children on your death. In fact, their share would be decided by the laws of intestacy which could mean a potentially long and expensive probate process for those hoping to benefit from your estate.
