We must verify whether our destination address is still active or no longer used. For Bitcoin transactions that allow each person to have several active addresses. This must be ensured first. If the transaction is related to business, then there should be a discussion first from both parties to confirm the transaction.
Another reason you should never discard you seed or private keys even if you don’t use them.. you never can predict if/when the need for it could arise. I get it that it’s essential for each party to come into agreement about which address to use for carrying out the business transaction(very essential) but still, you never know where the mistake could come from with you needing the access to wallet you thought you never need in the first place.
