There exist heavy tetraquark states [ital QQ[bar q]] [bar q] in the heavy quark limit. These states are stable with respect to strong interactions and hence must decay weakly. It is shown that the semileptonic decay depends on a single Isgur-Wise form factor, which can be expressed in terms of the Isgur-Wise form factors which govern the semileptonic decays of the [ital Qqq] and [ital QQq] baryons.
