Can daughter be held responsible for aging mother who refuses help and can not take care of herself properly?

If you feel Mom and SD need help and are refusing it, you may want to talk to APS and ask if they can do a "well check". Explaining to them what services there r available. If they refuse help from APS, at least u will have a record of it which will help protect you.

No, she is responsible for herself. I would just make sure someone has her Durable POA so when the time comes someone can make good decisions for her...it will happen, just a matter of when.

If you mean in a legal sense? Not unless you live with her....then you might have some custodial issues if APS got involved.

If she refuses help, that's mom fault. It's very difficult to help someone who doesn't want it.
