Your children will go to a guardian. A guardian is an adult who will take care of your children when they are minors, under the age of majority, when both their parents are deceased. If you do not nominate a person, the Probate court will appoint someone to be the guardian of your children and their estate. A nomination of a guardian can be named in your Last Will and Testament or in a separate document so the Probate court is aware of your choices.
There are two (2) types of guardians: guardian of the person and a guardian of the estate. They can be the same person or different people. You determine who will be in charge of your child and their estate. The Probate court will grant the guardianship according to your wishes or according to the laws of the state of California if your wishes are unknown.
Note: The above is general information and you should consult with an attorney to answer your personal questions and to have your estate plan drafted.
