My mother-in-law's tenant sent her a letter and said that he wishes to discuss with several issues of safety in his unit pertaining to county building codes. She replied with a letter and asked him what are the issues. He replied with a letter and without telling her what kind of issues, he wrote "we can discuss which of us should address these matters with the appropriate city and/or county agency at our meeting." My mother-in-law does not speak english well so cannot meet with him, so she requested him to keep communications in writings so her children (out of town) can reply on behalf of her. But he wrote "further attempts to facilitate resolution of this matter by deferring to friends or family members will not be acceptable". What should be our next step?
