Samantha Grenier, of Manchester, and her husband were sentenced to 15 years in prison last year.
Police say before that the 28-year-old posed as her lawyer and advised an ex-boyfriend to marry Grenier to help her get a more lenient sentence.
Grenier had told him she was pregnant with his twins. Police said they married last spring, but then he learned about the plot - and husband.
Grenier was charged with bigamy, falsifying physical evidence, and tampering with records. It wasn't known if she has a lawyer.
