Signing someone else's name on a check
Signing someone else's name on a check is generally considered forgery and would be illegal in most states, said Carol Kaplan, when she was spokeswoman for the American Bankers Association in Washington, D.C. But suppose an adult child signs an elderly parent's name because the parent is incapacitated, or a parent signs a child's name because the child is away at college. Guess what? Those signatures are still forgeries, unless a power of attorney is in effect.
"In most cases, it's on behalf of a loved one who probably isn't going to object, but people should know that that's forgery," Kaplan said.
