An ending should settle practical obligations instead of leaving them to goodwill.

Goodwill is a poor mechanism for anything that has to survive a bad month. When a partnership, a tenancy, or a shared arrangement ends on a friendly understanding, the details are usually left vague because writing them down feels like distrust, and a year later two people remember it differently and neither is lying. Clear terms protect the friendliness rather than replacing it.

Write down who owes what, by when, and what happens to the shared things. Agree it while relations are still warm.
