The Probate Court will decide who will administer your estate and who will become guardian of your minor children. The California Probate Code dictates who gets your money and your belongings.

An inappropriate person may be appointed by the court to administer your estate.
An inappropriate guardian may be appointed by the court.
Children will receive their share when they become “adults”, at the age of 18!
The beneficiaries may not be those you would have selected if you had been prepared and had completed your own estate plan.
