Distinguish help from authority
Informal assistance may be appropriate for organization but not for signing, withdrawing funds or changing ownership.
Keep transparent records
If someone is authorized to manage finances, clear records help demonstrate what was done.
Protect privacy
Only access information needed for the role actually held.
Use formal authority where required
Power-of-attorney, guardianship or other substitute-decision rules are jurisdiction-specific.
