Researching Existing Informal Opinions

The formal and informal opinions through June 30, 1994 are included in a deskbook entitled Missouri Advisory Opinions published by The Missouri Bar in 1995. Opinions included in the deskbook are indexed by topic and include an annotation to the particular rule(s) involved. A supplement containing informal opinions published from July 1, 1994, through December 31, 1995, came out in 1996.

Informal advisory opinion summaries that have been issued since June 30, 1993, have been published in The Missouri Bar BulletinMissouri Lawyers Weekly, and other local publications. The informal advisory opinions dating back to July 1, 1993, are online.

Because only summaries are published and informal advisory opinions are not binding, informal advisory opinions are not usually formally withdrawn. It is necessary to look to the more recent opinions for the most current general guidance on any given issue. Prior to the year 2000, the first two digits of the opinion number indicated the year. Now, the first four digits indicate the year.
