Judgment affirmed insofar as appealed from, without costs or disbursements.
Special Term properly granted the plaintiff a divorce on the ground of the defendant's cruel and inhuman treatment of him. The finding that she was guilty of cruel and inhuman treatment was based upon the resolution of the parties' conflicting testimony and we defer to Special Term's determination on this issue of credibility ( D'Amato v. D'Amato, 96 A.D.2d 849; see Davis v Davis, 83 A.D.2d 547). We also note that corroboration is not required to establish acts of cruel and inhuman treatment constituting grounds for divorce ( D'Amato v. D'Amato, supra).
Moreover, Special Term properly declined to award defendant a share of the amount by which plaintiff's printing business, Commercial Graphics, appreciated in value from the date of the marriage to the commencement of this action. Plaintiff's one-half partnership interest in Commercial Graphics is entirely separate property because it was acquired prior to the marriage (Domestic Relations Law, § 236, part B, subd 2, par d, cl [1]; see Pacifico v. Pacifico, 101 A.D.2d 709; Van Ess v. Van Ess, 100 A.D.2d 848), and Special Term's finding that defendant made no substantial contribution to the business during the relatively brief six-month marriage through her services as spouse, wage earner, homemaker or otherwise is fully supported by the record. Since defendant failed to establish that the business appreciated in value due to her contributions, whether direct or indirect, she was not entitled to a component share of such appreciation (Domestic Relations Law, § 236, par B, subd 1, par d, cl [3]; see Pacifico v. Pacifico, supra; see, also, Conner v. Conner, 97 A.D.2d 88, 98-99).
Finally, we note that the court did not abuse its discretion in awarding plaintiff possession of his clothes, television, stereo system, tools, and depression glass collection ( Blickstein v Blickstein, 99 A.D.2d 287). O'Connor, J.P., Weinstein, Lawrence and Eiber, JJ., concur.
