A more thorough explanation:

Consuetudinibus et serviciis

Consuetudinibus et serviciis is a legal term that means "customs and services." It refers to a writ of right that a landlord could use against a tenant who refused to pay rent or perform services that were owed to the landlord.

For example, if a tenant agreed to provide the landlord with a certain amount of crops each year as part of their lease agreement, but then refused to do so, the landlord could use consuetudinibus et serviciis to force the tenant to fulfill their obligation.

Another example would be if a tenant stopped paying rent, the landlord could use consuetudinibus et serviciis to demand payment and take legal action if necessary.
