Dedikate , There are a lot of so called high functioning but borderline developmentally disabled- mentally ill- personality disorder people out there so I too suggest you keep the same kinds of log notes that group home staff make about the clients in the homes I work in. carefully selected words though, EG When ( name ) was met for visitation transfer she appeared to be in a good mood then upon returning the children she appeared to be very agitated and verbally aggressed in front of the children by swearing ( inappropriate language ) to me . (including more information about bad behaviors as needed. Not perfect But one other thing you may want to seek legal advice about would be recording interactions with her such as transfer times where you may encounter her. ( as to your growing marijuana I know its possible with enough insulation barriers and air exchanging ventilation equipment that one can grow in a home and not even neighbors would know , ( I have a relative who had a husband who has grown in a specially built grow room in the basement of the home for almost 35years now and the only time there ever is a smell is when he is smoking it, when they were together I had been to their home a lot and never could smell it . BUT in your situation perhaps you want to install a deadbolt on the door to the basement to remove any possibility of the minor children being able to access that area of the home.
