A more thorough explanation:

IN TEMPUS INDEBITUM

in tempus indebitum (in tem-pəs in-deb-i-təm). [Law Latin] Hist. At an undue time.

In tempus indebitum is a legal term that means "at an undue time." This term is used in historical legal documents to describe actions that were taken at a time that was not appropriate or allowed by law.

An example of in tempus indebitum would be if a creditor tried to collect a debt from a debtor after the statute of limitations had expired. The statute of limitations is a legal time limit for how long a creditor has to collect a debt. If the creditor tries to collect the debt after this time limit has passed, they are doing so at an undue time and are in violation of the law.

Another example of in tempus indebitum would be if a landlord tried to evict a tenant without giving them proper notice. The law requires landlords to give tenants a certain amount of notice before they can be evicted. If the landlord tries to evict the tenant without giving them this notice, they are doing so at an undue time and are in violation of the law.

These examples illustrate how in tempus indebitum is used to describe actions that are taken at a time that is not appropriate or allowed by law.
