Boards and Associations Misrepresentation of Ownership in a Condominium (Ma)

My question involves a condominium located in the State of: MA

Hello all,

If someone who is not an owner of a condominium unit represents themselves as one what civil/criminal laws can be applied to them? What paperwork would they need to be able to legally exercise control over said condo unit? Power of attorney, I would think?

Thanks.
