So you can determine (a) who receives your property (and at what age), (b) who is the guardian of any minor children and how assets are managed for them, ( c) who is in charge of your assets and bills and does your business, (d) to confer additional powers on your executor so they won’t need court authorization to do virtually everything (pay bills, distribute assets, etc.), and (e) so your fiduciary won’t need to buy a surety bond (unnecessary expense -insurance policy ). On the other hand, if you do not have a Will, the “Statute of Descent and Distribution” states who receives your assets and how your estate is divided, the Probate Court determines who conducts your affairs, your minor children may be placed with someone you would not select yourself, and the time and expense to settle your affairs is usually much greater.
