A more thorough explanation:

namium

In the past, when someone owed money or failed to pay rent, the landlord or creditor could take their property as a way to get their money back. This process was called namium.

For example, if a tenant failed to pay rent, the landlord could take their furniture or other belongings until the rent was paid. Similarly, if someone owed money to a creditor, the creditor could take their livestock or other valuable possessions until the debt was settled.

These examples illustrate how namium was used as a legal way to force people to pay their debts or fulfill their obligations.
