Surely both parties would have to sign and declare that they are in a substantive relationship? I don't think a dodgy lodger could claim they've been having it away with the landlord for financial gain, unless said landlord also declared so?If someone allows a sofa-surfing friend or lodger to use their address for correspondence then do they become effectively married?
I do think a quick and easy online legally recognised union is needed though. Me and my partner are both divorced, been together 8 years and living together for nearly 3. I object to having a civil ceremony or a wedding in order that our agreed financial and fiscal arrangements are upheld. At the moment it all seems like a racket i.e. you can't just leave instructions or money to anyone without paying through the nose to some solicitor. There should be some element of self-service online, now that digital passports and photos etc are a thing, and can be used between various bodies like passport and DVSA. Yes there is space for fraud and exploitation, but I think that's always been the case
