In New Jersey, we have completed work obtaining approvals for site plan development of multiple plots located on one block in Newark, New jersey. The client has suddenly refused to pay fees when billed, and yet we have not yet submitted final stamped signed and sealed drawings for the already-approved site plan submission. Approval was obtained at a town planning meeting with unanimous vote of approval. The property address in question was 597-601, however this address represented multiple lots that the developer is intending to combine. Do we need to submit multiple liens on multiple plots? or is the address alone or one lot sufficient?
