Can I use someone else's REI dividend?

I understand that REI dividends can be a great source of passive income, but I'm curious about the legal and ethical implications of using someone else's REI dividend. Is it permissible to utilize another individual's REI dividend for personal or investment purposes? What are the potential consequences if I do so without their consent? Additionally, are there any specific rules or regulations that govern the use of REI dividends in this context? I'd appreciate your insights on this matter.
