Usually this is frowned upon. But I had a friend who was in your same shoes. She was helping her ex sister in law, since she had kids, to keep lights and heat on in the house. Well, her sister in law never paid her bills on time and utility companies would deny her knowing she was delinquent.
So then my friend started getting letters in the mail about. She's tried talking to her about making plans to have her pay her dues. Well, talks are nice but nothing changed. She ended up having to call them and tell them that her identity was stolen, since it wasn't her current residency.
Now, I'm one for helping others, but if it has any possible negative impact on your personal finances (even for the future), but don't do this! You can find programs that will help them better than your own personal identity. Best of luck!
