My 20 yr old stepson and his girlfriend live with my husbands grandparents and they are totally taking advantage of them. All they pay is $43 a month. They both work in fast food full time and don't pay their bills. Last week my stepson got his car repo'ed. They never have any money. They bought a 2000 ford mustang from a co-worker a couple of months ago and still haven't paid anything on that car either. I keep telling my husband that his grandparents are getting old and if one of them dies then the house will be sold. And there will not be a free ride anymore. I already told my husband that he can't come back and live with us, and my husband agreed. Not to long ago I went to the grandparents house and the my stepson and his girlfriend have taken over the house and have trashed it. The upstairs and downstairs look and smell so nasty. (grandma and grandpa can't climb stairs anymore). I just feel that the grandparents are being taken advantage of and what the hell are these 2 kids doing with their money when they don't pay their bills, cause I don't think they are doing any drugs. I have offered to put them on a budget before but they never follow threw. What is their problems?

They are being taken advantage of but until they want them out I don't see much you can do.
Their problem is they have a free ride and don't know the real world of paying bills. It probably will take the grandparents dying and them then being responsible for the taxes, bills, etc... before they even begin to think of changing. My neighbors father just died, mom died two yrs ago. He is around 40 and doesn't work. I don't think the reality is going to hit him until the house is taken for back taxes.

Until the grandparents want them out, nothing can be done.
And to be honest something you need to stay out of their business with, it is more first between grandparents and kids, and second between your husband, his kids and parents.

Untill the grandparents want them out, nothing can be done.

Honestly it is my business cause this is my family and I have raised my stepson since he was a little kid. And I'm not going to butt out... if I wanted that kind of opinion I would never have asked. I just feel bad that my husbands grandparents are being taken advantage of. But if something happens to them my stepson is not in the will to get the house. My husband is.

The problem is that legally by LAW you don't have a leg to stand on so technically it isn't your business unless you can step in and make things work without stepping on toes to the point of disrupting things to were they turn around and call the police, sue you or whatever.
IF he can deem them incompetent and legally take over their affairs then he might be able to pull something off legally.
