Estate assets refer to all the property, possessions and resources that are owned by a person or entity at the time of their death. This includes real estate (such as land, houses, and buildings), personal property (like cars, jewelry, artwork, and furniture), financial assets (stocks, bonds, savings accounts, etc.), insurance policies, and other valuable items. These assets are managed by a legal representative or an executor during the probate process to ensure that they are distributed according to the deceased person's will or state law if there is no will.
