prearrangement

This term describes a proactive approach to organization, emphasizing the elimination of uncertainty or chaos by establishing terms before a triggering event occurs. It carries a connotation of prudence and foresight, often used in professional, legal, or administrative settings to denote a formal pact or a structured plan.

In the specific context of end-of-life planning, the word takes on a more solemn and practical tone. It refers to the logistical and financial preparation for death, shifting the burden of decision-making away from grieving survivors to the individual who planned ahead.
