Thanks for info man. But I have no intention to break the law. I was just checking on any additional documents required to submit before hand. Property evaluation for a prior date for one cannot be obtained I guess.
I'm sure that was not your intention. However, saying/doing things like "put in a higher figure to avoid taxes when I sell and make a capital gain" and "not declare her income and show her as not working" will clearly put you on the wrong side of the law.
