The former The Bold and the Beautiful star and his fourth wife Sand divorced in 2002 after a six-year marriage, and Lamas filed legal papers last month (Nov14) to challenge their joint custody agreement.
He accused Sand of being an unfit mother and their daughters Alexandra, Victoria, and Isabella wrote letters to a judge asking to live with their father.
According to Tmz.com, the judge has now ruled in favour of Lamas by making him primary parent. The children will live with him and Sand will look after them every other weekend.
Lamas married his fifth wife Shawna Craig in 2011. He has three other children from previous relationships.
