By a pact signed November 1218 with Marianus II of Torres, his father secured his marriage to Adelasia, Marianus" eldest child.
He ruled every giudicato on the island of Sardinia at one point or another save Arborea. The marriage was celebrated in 1219. Ubaldo inherited the Giudicato of Gallura in 1225.
He subsequently exercised the regency for Benedetta until 1232.
They unanimously acclaimed Adelasia, whose husband could well uphold her right. So they in turn elected him judge as well.
In 1237, Pope Gregory IX sent his chaplain Alexander to Torres to receive recognition from Adelasia of papal suzerainty. Ubaldo did not, however, recognise any authority over Gallura other than the ancient authority of the Pisan archdiocese.
Ubaldo drew up a will in January 1237 at Silki.
