Apologies if this question has already been asked and answered elsewhere but I am wondering about what my residential address is for the purposes of an onshore partner visa application. Since 2016 my wife and I have lived together in an apartment that I own in the US. In December my wife (an Australian citizen) flew back to Australia and I joined her at the end of March. Since mid April we have been living in her mother's house while we look for work and apply for this partner visa. My question is, should I put my mother-in-law's address as my residential address on all the forms. I am living here (and will be for the next few months) but I have no proof that I live here (I've only received one piece of mail, no utility bills, etc.). Any advice would be greatly appreciated.
