Property that starts out as nonmarital may end up marital.  This process is called transmutation of nonmarital property.

“Property, nonmarital at the time of its acquisition, may be transmuted (1) if it becomes so commingled with marital property as to be untraceable; (2) if it is titled jointly; or (3) if it is utilized by the parties in support of the marriage or in some other manner so as to evidence an intent by the parties to make it marital property.” Trimnal v. Trimnal, 287 S.C. 495, 339 S.E. (2d) 869 (1986); Wyatt v. Wyatt, 293 S.C. 495, 361 S.E. (2d) 777 (Ct. App. 1987).
