Who is responsible for carrying sinkhole insurance? The renters or the landlord?
My mother and father have a sinkhole in their backyard. They rent their home and have made the landlords aware but they are refusing to fix it.
If your parents are renters, they are not responsible for the property — just their own liability and possessions — so it's not required to have sinkhole insurance since that's property-related. The landlord has to maintain safe living conditions for their property. I would push the issue with them if the property isn't safe to live in before it becomes a bigger issue. If you have any other questions, don't hesitate to ask.
