Erika, I think you need to look up the definition of Power of Attorney
No locksmith is going to jail and/or paying a fine, or getting their certification revoked, for Yandy, or anyone else.
Power of Attorney: the authority to act for another person in specified or all legal or financial matters.
For all intensive purposes (especially if it is broad, as in "ALL legal or financial matters) She is him, so legally, that apartment belongs to Yandy, Mendeeces, and Erika.
