Both Richard and Robert are right.  A good report will be clear and well-written.   Plain, basic American English should be used to describe things in detail.  I mean, come on people;  we learned to write concise, precise, and complete book reports in elementary school.  In doing so, we learned how to annotate and construct bibliographies and break complex ideas down into simpler sentences. 

  On the other hand, for those clients who either have low comprehension or who get poorly written reports, the option of having a reasonable dialogue about the papers is good.  Heck, sometimes your spell-check misses an item or changes a word inadvertently.  Sometimes you transcribe a document number wrong.  Sometimes you accidently omit a data field. 

  Also, explaining your research methodology can be important, as clients may be looking for something outside of what they requested or understood the scope of your report to cover.   For this reason, we only do business by email and we addendize the client email chain with us into the report for clarity purposes.

  Since the research and research notes are all done for the report, we include all research notes in our report, omitting none, so that there is never any additional information to subpeona outside of the report;  the report has it all.   Good policy for our firm, and we've never had a claim to this day.

  Finally, we include a long list of disclosures, notices, and disclaimers involving public records in our reports which supplements our research and includes much information about our methodololgy up-front.

  Even a simple date-down is a long report, for that reason, but very thorough. 

  Opposing council on one recent case was so impressed with the completness and accuracy of our report since we reported on encumbrances missed by the title company and reported clearly on inaccurate postings that the title companies included in error, that they are using our research services from now on.  lol
