A TASMANIAN man has pleaded guilty to the rare charge of bigamy after forging divorce papers to marry another woman.

In what has been described by Tasmania Police as an "extremely rare and unusual" case, 43-year-old Nicholas Trikilis appeared in the Hobart Magistrates Court yesterday charged with bigamy, The Mercury reports.

Trikilis didn't hide the fact he was a bigamist.

After filing fake divorce documents to marry his new bride, Katrina May Phillips, in April 2008, Trikilis sent his wedding pictures to the Mercury in July of that year to celebrate the special occasion.

The happy snap published on July 8, 2008 showed the couple, family and friends in the Royal Tasmanian Botanical Gardens.

Ironically, the overdue divorce to his legal wife Kerri Anne Statton is scheduled to be heard in court tomorrow, but has been postponed until the current legal matter is resolved.

Trikilis, of Coningham, yesterday admitted forgery, using a forged document, giving defective notice of his divorce and giving false information offences all relating to the bigamy charge.

The call-centre operator admitted falsely trying to end his marriage to Ms Statton by signing a document on January 30 stating he was already divorced.

Trikilis then attended the Family Court in Hobart and presented the false document to Commonwealth public servant Elizabeth Gray on April 18.

He married in a civil ceremony on April 26.

Two days later, Trikilis filed the false divorce papers along with his marriage papers.

After being separated for almost a decade, Ms Statton learned of her separated husband's new wife in late 2008.

Magistrate Michael Daly yesterday asked police prosecutors for their help in previous sentences for bigamy, having not come across the charge before.

The last bigamy case in Hobart, in 2005, involved disgraced former British policeman Richard Eames who, after leaving his wife of 26 years in Britain, married a Tasmanian woman so he could stay in the country.

Before sentencing Eames to 21 months' jail with a 12-month non-parole period, magistrate Ian Matterson said the problem with bigamy was that "you end up with two mothers-in-law".

Trikilis will be sentenced on April 15.
