A Victorian policeman groomed and abused a 14-year-old girl and tried to convince her to move to France so they could marry, a court has heard.

Mario Simon Didulica allegedly abused the girl between November 2009 and July 2010, when he was aged 38, a serving officer and married with two children in a Geelong suburb.

Close to the beginning of abuse, he gave the teenager a passport application so they could travel to France to marry, Melbourne Magistrates Court heard on Tuesday.

The girl hid the form in a locker.
