The nonmesonic weak decay of {sub {Lambda}}{sup 3}H is evaluated microscopically in the pion exchange model. The correlated three-body wave function of the hypertriton is approximated by a bound {Lambda}-deuteron system obtained by averaging the {ital YN} interaction over the deuteron wave function. The relevant matrix elements are calculated in momentum space. The resulting decay rate is 4.9% of the free {Lambda} decay rate.
