Callan Elliot has joined the club on a deal running until the end of the season, subject to international clearance.
The New Zealand internationalist makes the move to Fir Park, having most recently been with Wellington Phoenix.
24-year-old Elliot was born in Dumfries but moved to New Zealand at seven years old and has spent the entirety of career abroad until now.
“Callan has good quality and has impressed out in the A-League,” manager Stuart Kettlewell said.
“I’m trying build a squad here and we have been looking to add quality and depth in this area of the park. Callan ticks both of those boxes so it’s great to get him in the squad.
“He’s an international player and someone I think can add a lot to the team.”
He made his professional debut with Kiwi side Tasman United where he made 17 appearances and attracted interest before subsequently moving to Wellington in 2018.
Over two spells at the club, Eliot made 53 appearances for Phoenix senior side before leaving the club in March 2023 having failed to agree on a new contract with the club.
“It’s great to say I’m a Motherwell player,” Elliot added.
“I’ve been training hard and I’m looking forward to get going. The boys are great and have made me feel very welcome so far.”
The full-back is also a New Zealand internationalist, having made three appearances so far for the Kiwis. He was named in the New Zealand squad for the March internationals and was named in the starting lineup against China. He made his third appearance in June of 2023.
Callan Elliot will wear the number 29 kit this season.
