This law worried me. I have 4 kids and don't want them to be obligated to support me or my DH in old age. I certainly would never want them to go into debt over me. I had them out of love.
On the flip side my parents have my fathers retirement and are average income. Dad was a truckdriver. Mom was disabled many years ago due to a medical error with medication. My mom has recently had kidney cancer, and my dad has had a heart attack about 6 years ago. I would do whatever I could to take care of them. They would never want my DH or myself to go broke supporting them. They even said they would never want to move in with us if one of them died, because they wouldn't want to be a burdin.
We live out of state from my inlaws (Thank God). But FIL has quite a bit stocked away in different things. Even so I think if the IL's wanted to move in with a child it would be DH's sister. First off they would never move out of state and away from family. SIL owns her own home with no kids and plenty of room. She is recently divorced. I think my IL's had something to do with it big time. To much interference. Never cut the apron strings either.
Anyhow, here is some info I found at:

States with filial responsibility laws are: Alaska, Arkansas, California, Connecticut, Delaware, Georgia, Idaho, Indiana, Iowa, Kentucky, Louisiana, Maryland, Massachusetts, Mississippi, Montana, Nevada, New Hampshire, New Jersey, North Carolina, North Dakota, Ohio, Oregon, Pennsylvania, Rhode Island, South Dakota, Tennessee, Utah, Vermont, Virginia, and West Virginia.
I hope it's helpful.
