I've had many problems with my MIL, but now that things have become financial, it's getting worse.
About 6 months ago, we get a call from a collection agency saying that they have been trying to get a hold of DH for 4 years about 2 medical bills that were never paid. The bills were for DH when he was a freshman in college, 18, and living at home on his mother's insurance. The collection company had been sending bills and notices to the IL's house and calling there and getting no response.
We find out that MIL said she thought she had paid them, but apparently not. She never mentioned this to us in 4 years or ever gave us the bills that were coming to her house. It was only $150 for both bills and could have been taken care of every easily if we would have known. The bills were paid for finally and it took almost a month to get MIL to try and hunt up the bills so we could see what the payments were for. All along she had every bill she had received at her house and had just ignored the fact that there was an overdue amount on them and never paid them or told us about them so we could pay them. (The reason I say pay them herself is because at the time of the medical bills, DH was just starting college, just out of high school and living at home (we had not met yet). His parents always paid for his medical expenses, car insurance, ect.)
Now DH has a mark on his credit from these that won't go away for like a year or so, since they were sent to a collection agency. I was furious when I found out and told DH that technically his mother should pay for the bills since at the time of them it had been her responsibility. I might have been way off base here, but at the time I was upset and all I could think is "Why would a mother do this to her son?"
In the end, MIL went to her mother and asked her to pay for the overdue bills. Even though ILs both have jobs and should be pretty financially dependent, they are not and MIL relies on her parents to pay all of their bills and expenses, including school things for the two younger SILs.
I realize that might have been the reason these bills were never paid because they never got shown to the GMIL, but if MIL would have came to me and DH at the time the first bill showed up, then I might have been more apt to paying the bills. Once it had been 4 years and things had just been ignored, I felt that we were just showing her that she can always do what she wants.
Now the fact is, DH just bought a new truck and is wanting to sell his old car. His sister just turned 16 and we thought his grandparents might want to buy it from us for her, so we told them we had it for sale and how much we were asking (lower than what we would ask a stranger, since they are family). MIL said that we should give SIL the car and that she wasn't paying us for a vehicle. She thinks that since it's family, we shouldn't ask them to buy it. I refuse and told DH that that would not happen. Not only is that not fair to ask of us, but the money from the car will help with payments on the new truck. I just don't trust them with money issues after everything that's happened.
I guess more or less, I just want to get other opinions. I know I probably acted wrong on insisting MIL pay the late bills, but at the time, I felt it was the only way not to let her run all over us. Any advice?
