An estate, in common law, is the net worth of a person at any point in time alive or dead. It is the sum of a person's assets – legal rights, interests and entitlements to property of any kind – less all liabilities at that time. The issue is of special legal significance on a question of bankruptcy and death of the person. (See inheritance.)
Depending on the particular context, the term is also used in reference to an estate in land or of a particular kind of property (such as real estate or personal estate). The term is also used to refer to the sum of a person's assets only.
The equivalent in civil law legal systems is patrimony.
