I know a common piece of evidence for living together is a lease agreement with names of both spouses or mortgage statement with both names. In my case, I owned the home before we got married, having the mortgage be in our names would require refinance and all sorts of bureaucratic headaches. Would it be fine if I got a letter from the HOA which states that we are both registered to live at my residence? (you have to submit application / register with HOA if a new resident comes to live) Of course beside this, there's bunch of other evidence showing my wife's address being here including bank statements, driver licenses, wife's W2, health insurance and medical bills, etc. Thank you in advance.
