For years, after the first word processors were invented with cut and paste abilities, the bulk of realestate and contract work has been steadily eroded by this cut and paste work by, at first, secretaries and latterly by robotised scripts.
Each agreement has all possible variable areas (name, address, locations, special clauses etc) identified as numbered fields. Staff provide the exact data for each numbered field and special claus and removes unused special clauses of which there may be hundreds for all manner of contract or real estate aspects. In seconds the substitution is completed and the final agreement inspected by a lawyer - often in India, and then sent to the billing firm for final inspection and review and then for signature.

Most but only if the information that they deal with is available as data rather than Microsoft Word and Excel files.
