The short answer

Because memory is unreliable and money changes relationships. Written terms give both people the same reference point.

  • Nobody has to guess what was meant six months later.
  • A difficult month becomes a practical problem, not a personal one.
  • Both people can see progress instead of wondering about it.

KinPay tip

Write the terms down while everyone is still relaxed about the money. It is much harder later.

Key takeaway

Because memory is unreliable and money changes relationships.
