That is something many people don't understand, especially when the loan comes from a parent. They think that just because it's their parents lending them money, they can get away with giving nothing back. Parents are supposed to take care of their children; that's true, but not when they are already adults who are supposed to be financially responsible for themselves.
In this case, the parents lent their son $50.000 dollars to buy a house. He was supposed to give back the money over the course of 10 years, so it wouldn't be a burden. The parents did that with their other daughters, and it worked wonderfully, but not with him. Apparently, he's a very financially irresponsible man. He has credit card debts and other loans with the bank, and yet he spends his money on expensive vacations, buying a new pickup truck, and eating out constantly. He refuses to pay back his parents, accusing them of being greedy and trying to destroy his family. The parents regret lending him money, and their other daughters are furious at them for doing it, especially because they made sure to pay their debts.
Here, they have at least two options. The first one is to seek legal advice and force the son to pay them back. They had a contract, and he's not abiding by it, so the parents are perfectly entitled to let the justice system take over. The second option is to let it go. But not just let him get away with it; no, no, they can cut him off his will. Since he refuses to pay them back, they can decide he has already received his inheritance and not give him another single penny ever again. Sounds fair, right? If the guy is going to choose to be irresponsible about his finances, he can take the consequences of it.
What do you think? Would you let it go or force him to pay you back? Can you think about any other solution for these parents?
