It sucks to have to lie about things...but when you have a serious health condition and you have no other way you have to. We were fast approaching living in a card board box after we got married because I lost SSI and MedCAID, we thought I would get to keep it because he didnt make that much money and I didnt work. We were wrong some where....we had even looked at income requirements. So we got divorced and I told them I still lived with him but as a roommate, they slightly questioned it, really all the social worker asked was "is that going to work?" now I'm sure some might question it more...but fight back asking if they are discriminating on your illness/race/age/marriage status/where and who you live with. They hate the word discriminate it gets them in trouble...but hate to say it it usually only works with certain people. I lived with my "ex" for a year then we moved. and when we moved I just said I lived alone and all they asked was what my rent was. We still live together. But here in texas no one has surprise house checks....they call maybe once a year to check on your status....meaning has your rent changed have you gotten any other money. Its really dumb. I mean if they had regular checks on people it would be a pain in the butt but atleast it would weed out the cheaters. I dunno there are all sorts of problems.
I say check with your state and see what kind of laws are for common law. Now assuming he lives on his own, it will be easier for bills and he can keep the same status he has with SSI and medicaid. So say you move, just call the Social security office and say hey I moved here is my new address, they ask if you live with any one, say no. If he tells the social worker at the ssi office he lives alone then they have to take his word for it. No one comes to the house and checks, well at least not here. And all documentation doesnt go through them at all. They dont check apartment agreements or anything UNLESS you say you have a roommate. But to be on the safe side get all information you can. Ask and see if they need documentation such as electric bills proving your both on the statement....just ask that whether or not you intend to do so....and if they say no then they dont check anything, they just take your word on things. On to the roommate thing. You can tell them you have a roommate. They will ask if the roommate helps with any bills...generally a roommate helps with half of everything. So he can tell them you pay for half of everything but you dont help him out with anything else...just regular house bills and house payments. That may affect how much SSI he gets but it wont show up as a common income and he will keep everything. BUT you will get into the common law area. If you have no common law just say that your a roommate, they dont even ask for the roommates income all they ask for is how the bills are split. If you do have common law he will have to say he lives alone. But like I said if they dont check documentation it wont matter if you have everything mailed of yours to the same place or put down same residence....but just in case on medical type things put down seperate addresses and a cell phone for emergency contact info...the seperate addy could be your parents. Be sure you never sign medical things or you will be liable for payment, only get him to sign. IF you have a cell phone you would want to put that down as your emergency contact number anyway because you would have it with you. If you dont it could be his parents number and they will call you, or your parents number. But since they do see medical things when filling bills, i dont know if it shows up whose on that type info or if that type of info is protected under HIPPA i believe it is...so it wouldnt matter.
Best thing to do is look at where you live. Find out about common law...if there is non you have nothing to worry about your just a roommate. If there is common law then he lives alone when he calls them.
Sorry this was so long. I hope you have a great ceremony. Oh by the way you usually cant get a preacher or church to marry you with out legal papers, unless you know someone...because preachers PLUS the church can get into alot of trouble legally if they do.
