The legal term used for when a person passed away without a Will is “intestate.” If the estate is worth more than $150,000 then the County Superior Court will need to oversee the administration of the estate. The person appointed to handle the estate is called the “Administrator.”
If there is a claimed unknown heir, unknown spouse, creditor, if you disagree with how the estate is being handled, you can file an objection, and you are entitled to a trial on the issue.
Administrators typically need to post bond, unless all heirs waive the need for a bond. A bond is an insurance policy against misuse of the estate's funds.
