Rembert was applying recently for Social Security benefits when government employees found she had an outstanding probation violation from a 1981 welfare theft conviction.
She had been placed on five years' probation and ordered to repay $3,700. She paid $695 and says she erroneously believed her husband, who is deceased, had paid the rest.
So she was faced with a possible 1 1/2-year prison sentence when Ellington, 57, decided to intervene.
"The system failed," said Ellington, a consulting business owner and former social worker, of the unpaid debt that had previously been ignored. "There are times that you have to meet people at their need. It was just the right thing to do."
Rembert was in tears Thursday at the Hamilton County courthouse.
"I'm glad it's over," said Rembert.
She uses a walker, but she rose from a bench to hug Ellington.
"Bless your heart," Ellington told her. "God has blessed me and my family and we want to pass on the blessing to you."
