Although the facts alleged in the complaint are taken as true, Libertad v. Sanchez, 215 F.3d 206, 208 (1st Cir.2000), the facts must be sufficiently well pleaded to support the requested judgment; otherwise, the district court may require “such hearings ... as it deems necessary and proper____” Brockton Sav. Bank v. Peat, Marwick, Mitchell & Co., 771 F.2d 5, 12 n. 8 (1st Cir.1985) (quoting Fed.R.Civ.P. 55(b)(2)). Damages “must be established by proof unless the damages involve a ‘sum certain’ or are for liquidated damages.’ ”5 Katahdin Paper, 231 F.R.D. at 113 (citations omitted).
