Thanks for your replies.. We submitted the main application and paid the fee yesterday and the main application is currently in progress. I am still worried now because of some conflicting advice that we've answered the questions in the application incorrectly.
Where it asked for relationship status (which is currently de facto), followed by date relationship began, we put our "anniversary" date of June 2012 even though we didn't live together then. And then where it asked for "date committed de facto relationship began" we obviously put the start of our de facto relationship, and did the same with question "Do the sponsor and the applicant have a mutual commitment to a shared life as husband and wife, or as de facto partner to the exclusion of all others? / Date sponsor and applicant committed to a shared life together to the exclusion of all others"
My sponsor is filling out his application now and was going to put the same times & dates as the main applicant in his application, in those same questions asked. But now we're not sure if he should just put the de facto date as the "date relationship begun", as we don't want to have conflicting applications!
How worried should we be if we've accidentally put the wrong dates in the applications? :/ It's just been so confusing because the questions are repeated so many times but are worded differently etc.
We have our partner statements explaining the entire timeline and history of our relationship so it's all very clear in that, and we have evidence of living together since June 2013..
