Here, we present weak lensing (WL) mass constraints for a sample of massive galaxy clusters detected by the South Pole Telescope (SPT) via the Sunyaev-Zel'dovich effect (SZE). We use griz imaging data obtained from the Science Verification (SV) phase of the Dark Energy Survey (DES) to fit the WL shear signal of 33 clusters in the redshift range 0.25 ≤ z ≤ 0.8 with NFW profiles and to constrain a four-parameter SPT mass-observable relation. To account for biases in WL masses, we introduce a WL mass to true mass scaling relation described by a mean bias and an intrinsic, log-normal scatter. We allow for correlated scatter within the WL and SZE mass-observable relations and use simulations to constrain priors on nuisance parameters related to bias and scatter from WL. We constrain the normalization of the $$\zeta$$-M₅₀₀ relation, $$\mathrm{A_{SZ}}$$ = 12.0$$+2.6\atop{-6.7}$$ when using a prior on the mass slope $$B_\mathrm{SZ}$$ from the latest SPT cluster cosmology analysis. Without this prior, we recover $$A_\mathrm{SZ}=10.8_{-5.2}^{+2.3}$$ and $$B_\mathrm{SZ}=1.30_{-0.44}^{+0.22}$$. Results in both cases imply lower cluster masses than measured in previous work with and without WL, although the uncertainties are large. The WL derived value of $$B_\mathrm{SZ}$$ is $$\approx 20\%$$ lower than the value preferred by the most recent SPT cluster cosmology analysis. The method shown in this work is designed to constrain cluster masses and cosmological parameters simultaneously and will form the basis for subsequent studies that employ the full SPT cluster sample together with the DES data.
