Keep the approval, quotation, findings and final documents in the same property file. If the repair solution differs from the approved alteration, return that change to the responsible estate process before installation. Written approval of a proposal does not show that the installed work matches it or that electrical testing is complete.
For a sale, request the relevant shared records early instead of asking a contractor to produce a new document for whichever fence is easiest to reach from the unit. If the papers are incomplete, describe the gap clearly. An inspection can establish findings for its agreed scope, but it cannot settle an ownership question merely by visiting the garden.
