hi jennm,i went through the same problem as your having,in the end i went to the local CAB ( citizens advice buruea ),and they phoned the legal department of the council,and they said there would not be a problem,just for me to write down what was needed,they would not say it was ok for my future wife to move in...but said i could move SOMEONE one in long as it didnt make the property over crowded,....hope that helps you
