Using the Mark II detector at the SLAC Linear Collider, we search for decays of the {ital Z} boson to a pair of nonminimal Higgs bosons ({ital Z}{r arrow}{ital H}{sub {ital s}}{sup 0}{ital H}{sub {ital p}}{sup 0}), where one of them is relatively light ({approx lt}10 GeV). We find no evidence for these decays and we obtain limits on the {ital ZH}{sub {ital s}}{sup 0}{ital H}{sub {ital p}}{sup 0} coupling as a function of the Higgs-boson masses.
