The interplay of prospective experimental information from both the LargeHadron Collider (LHC) and the Linear Collider (LC) in the investigation of theMSSM Higgs sector is analyzed in the SPS~1a and SPS 1b benchmark scenarios.Combining LHC information on the heavy Higgs states of the MSSM with precisemeasurements of the mass and branching ratios of the lightest CP-even Higgsboson at the LC provides a sensitive consistency test of the MSSM. This allowsto set bounds on the trilinear coupling A_t. In a scenario where LHC and LConly detect one light Higgs boson, the prospects for an indirect determinationof M_A are investigated. In particular, the impact of the experimental errorsof the other SUSY parameters is analyzed in detail. We find that a precision ofabout 20% (30%) can be achieved for M_A = 600 (800) GeV.Comment: 12 pages, 5 figures, minor modifications, version to appear in JHE
