How should I choose whether my delivery policy is a legally binding document or not?

Alasdair Taylor's answer to How should I choose whether my delivery policy is a legally binding document or not? (337214190)

Do you want the provisions of the document to be legally enforceable in court?  If so, the policy should be expressed to be legally binding and formally agreed/accepted by each party.

If however you want the policy to merely describe usual practice, without creating binding commitments, then it should state that it is not legally binding.
