Hey there ladies and gentlemen of the internet. Money makes the world go round, it makes the grass grow, the leaves fall in autumn, and for everyone to buy themselves new Nikes. It's a fundamental part of the functioning society whether someone likes it or not, and it's not to be taken for granted. Money is more important than ever these days, with soaring rent prices, eggs being unaffordable, and most of the world's jobs becoming more and more obsolete. But enough talk about money. The only thing more cynical of a conversation than money is family. 

Family dynamics never cease to disturb and perturb every part of one's life. A mere text message can send you flying into outrageous abandon at the fury of a simple sentence that your mother sent you. "Why is she always like this?" you ask yourself. Sometimes you may even feel as though you're the parent and they're the child. Or when dad brings out his sass, you just don't know where they get the nerve. 

In the story below, the protagonist is having a sisterly squabble. Not only is she enmeshed in a sort of family feud, but there's money involved as well. So now read the full story below, and be grateful it isn't you right now.

    AITA for refusing to sign for my sister's loan after she tried to do it behind my back?

    So, I (F, 26) and my older sister (29) inherited a house from our grandparents a few years ago. It's a two-family house, and both of our names are on the deed, so we both technically own it. We've been living together ever since, though we've had our fair share of arguments about the place over the years.

  • It's understandable that with the sister's past with money and finances that she wouldn't want to meddle with money things. Trust isn't just about cheating or lying, money and reliability is a huge part of trust. If she thinks her sister could potentially ruin her credit, or lose their home then it's a risk she shouldn't be taking.

    A few days ago, I found out that my sister has been trying to take out a loan against the house. She didn't tell me about it, so I only found out after seeing some paperwork with both our names on it. Naturally, I got pretty upset and confronted her about it. She tried to brush it off, saying she just needed the money for "some

    stuff," but when I asked her more details, she couldn't give me a clear answer.

    I told her if she wants to take a loan out on the house, she needs to buy me out. I'm not comfortable with her using our shared house as collateral without me being involved in the decision. But she got mad and said, "You're being dramatic. I'll take care of the payments, you don't have to worry about anything. Just sign the papers, and you won't have to do anything."

    The thing is, I know her. She's been irresponsible with money in the past-missing credit card payments, struggling to pay rent, and even not paying bills on time. I just don't trust her to keep up with the loan payments, and if she misses them, we could lose the house. So, I told her, "I'm not signing anything. If you miss the payments, we both could lose

    everything. I'm not willing to risk it."

    She got really defensive and told me I'm being selfish and not supportive. She said I should trust her, that she'd never let the house go. But honestly, I don't think I can trust her with something like this, especially since I know how bad things could get if she misses a couple of payments.

    Now she's mad at me and calling me unreasonable, saying I'm trying to sabotage her and that I'm just being difficult for no reason. So, AITA for refusing to sign for this loan and telling her she needs to buy me out instead?

    Candid Process1831 • 7h ago NTA! Let here buy your share of the property and then she can do whatever she wants. If she wasn't honest from the beginning then for sure she got something to hide! Take care

    frivolous-lola • 7h ago NTA!!! don't sign, protect yourself and stay clear of the mess. It's really suspicious that she gets defensive when you try to know more about her need for a loan, if you're gonna be involved it's perfectly acceptable to know what you're in for.

    Also be thankful this is happening early on, this is a telltale of way worse things that could come your way. I'd look into buying her share and keeping your assets separate from her. If possible, that would be a much safer way to help if you want to be involved.

    asafeplaceofrest • 7h ago NTA - stand your ground, and what kind of "stuff" does she need to buy? If she needs a loan, she can go to the bank and get a consumer loan. If she can.

    Anxious-Routine-5... • 7h ago NTA. You're being smart and protecting yourself. Your sister is already being shady and shown she can't be trusted. It sounds like the time has come for one of you to buy the other out.

    Jerold62712 • 7h ago She already signed your name? Under no circumstance condone that and contact the loan officials and tell them that you found some people with with your name forged and they should be particularly careful.
