I dont think it would be hard for them to figure out they were living common law once they look at the applicant's 10 yr activity history and the sponsor's travel history
@ycam
CIC's definition of common law is that u and ur partner lived together for 1 continuous year with no breaks, NOT 1 year of a continuous relationship without living together for a year. I hope u can understand the difference. As for your friend who got his app accepted, either he was extremely lucky, committed misrepresentation, or maybe they really did live for a year but you misinterpreted his case.
Either way Im personally extremely appalled that you would not only ignore the advices of these highly experienced members here, but also even ignore CIC's own definition of common law, and still proceeding with an app thats surely doomed to fail. I hope your relationship can withstand this additional stress of wasting at least 8 months of time due to your own negligence.
Your app WILL be refused, and when it does I hope you will do it properly and heed these guys' advices. And please do not try to appeal the refusal, you will only compound the problem
