John Hughes has moved quickly to strengthen his Pars side after a disappointing 3-0 defeat at home to Arbroath and Lawless will go into the manager’s squad as soon as the January window opens.
After completing a medical at East En Park, Hughes confirmed the 30-year-old is almost ready for his first-team and came through a bounce game against Livingston recently, scoring a goal off the bench.
“He brings SPL experience and is one that can unlock the door with a wand of a left-foot,” said Hughes. “He can play a pass and look after the ball and works very hard and is a winner.
“He’s everything we want at the club.
“I have chased him since I was at Inverness. It has been a long time coming and I’m delighted it is over the line.”
Lawless played six games for Motherwell this season before leaving Fir Park by mutual consent in October.
