Scenario: Architect designs plans for a townhome development. He charges a 1/2 to get started, and the remaining once the plans are done and stamped. The client doesn't receive the plans until they pay. This townhome development being funded by an individual investor plans to build 35 units. To keep his costs low the investor pays for chunks of the plans at one time and builds them as he goes. The architect has given him the first chunk of the plans, but since they are townhomes they are similar enough that the investor has just reused the same chunk to build all the units. How do you file a lien in this situation when the construction has already started?
