What should I do if I need a TM30 form for immigration but I'm not on the lease and my partner won't add me?

Some of the advice here contradicts what i was told by immigration in Chiang Mai just a week ago.. they explained that if i stay in a hotel, then it is the hotel's responsibility to register my residence there.. ie. file an online TM30.. but if i later move into a private residence, then i must register again.. if you live with a resident landlord (or with family or friends) then it is their responsibility to register you and they should assist you in your attempt to file the TM30 by providing copies of any documents needed.. in my case, i recently arrived in CM to stay in our own property.. which is owned by my Thai wife.. but i failed to file my TM30 in good time.. because of my ignorance over the hour deadline to do it.. and of course we got fined for this indiscretion.. but immigration stated that if i could prove any prior residence in a hotel etc (which had failed to register me) then they would review the imposition of the fine.. but they indicated that i would still have needed to register a TM30 after leaving the hotel and going to live in a private property.. judging by earlier comments it sounds like different provinces operate different practices then
