Man takes in wife's younger sister to help her prepare for a job hunt; 3 years later, she's still unemployed. Wife blows up when he suggests she move out: “Are you treating her like dead weight?” [This Is the Law]

[Financial News] A man’s story has emerged: He began living with his wife’s younger sister, expecting she would stay for about a year while he helped her prepare for a job, but more than three years later, she still has not moved out.

On the 4th, a video titled “My sister-in-law has been living at our house for three years. Can I force her to leave?” was posted on the YouTube channel “Lawyer Yang Na-rae.”
A, who is in his late 30s, is said to have married his wife after a long relationship, and they have a 5-year-old child. A says he had been close to his wife’s younger sister even before the marriage, and that they remained close after they had a child, with her visiting every weekend to play with the child.
His sister-in-law kept failing as she prepared to find a job, and had difficulty traveling from her family home to a job-preparation academy and interviews. A then offered that they live together. Thinking her job search would take no more than a year, however long it lasted, A readily told her to stay in their spare room and prepare for a job without having to spend money on rent or a deposit.
But even in her second year, his sister-in-law had not found a job. Discouraged by repeated failures, she left her room less often and no longer seemed to go to her academy or attend interviews.

After three years, A suggested to his wife, “We’ve helped her for a really long time—three years—and we need to make a room for our child. I’m uncomfortable, and I think your sister is uncomfortable living here too, so let’s help her find a place of her own and move out. She probably doesn’t have a lump sum right now, though, so let’s lend her the deposit without charging interest.”
But his wife reportedly got angry, saying, “You were the one who told her to come live with us, and now you’re treating my sister like dead weight and kicking her out? You shouldn’t have asked her to move in in the first place, then.”
When A asked, “Is your sister actually looking for work?”, his wife angrily let slip what she had been hiding. According to his wife, her sister had been suffering from depression after failing to find a job and had not even submitted a résumé for more than a year. His wife had been giving her sister spending money every month.

Lawyer Yang Na-rae, who heard the story, pointed out, “This isn’t helping your sister; it’s a way of ruining her.”
She went on to advise, “The things your wife has demanded, such as ‘Can’t you do that much for my sister?’, could be cited as grounds for marital fault,” adding, “You should gather evidence of the relevant conversations.”
She also said, “Because the husband owns the home, if there is evidence that he let her live there for a clearly defined period, and that period has passed but she still hasn’t moved out, he can file a lawsuit seeking possession of the property.” However, she added, “In this case, no specific time limit was set, so it seems important for the husband to clearly tell her, ‘Please move out by this date,’ and set a deadline.”
However, before going to court, Lawyer Yang suggested explaining the situation to his parents-in-law and asking them to mediate. She advised that if even they oppose the sister-in-law living independently and criticize A, he should seriously consider divorce.
