Form books provide sample forms or drafting language and information about their use. The examples can get you started, but make sure you understand the relevant primary law and demands of your jurisdiction and adapt accordingly.
The Iowa Code Annotated (which includes the Iowa Rules of Court) includes some Iowa-specific forms. The easiest way to locate these is to use the index to the Iowa Code Annotated, which also reproduces forms from both the Code and the court rules. Online code options are available here.
The Iowa State Bar Association produces this collection of sample Iowa legal forms. The library has a paper set. Individual practitioners can also purchase it electronically from the ISBA as fill-in forms. To learn more about purchasing IowaDocs, click here.
Although no longer being published (the last update was released in 2002), these books may still provide a useful starting point for drafting civil procedure forms. The judicial branch provides pdf versions of forms for civil procedure on their website, which you can access here.
Books on particular legal subjects may also contain related forms. See the library's Legal Writing and Practice Materials guides for a list of other sources to consider, notably the Iowa State Bar Association manuals and the Iowa Practice Series.
In SuperSearch, the Drake Libraries catalog, locate other works with forms, by a) doing a subject search for Forms (Law) or b) doing an advanced search that includes “forms” in "Any field” and a word describing what area you're researching in the subject box, title box, or another “Any field” box. For example, you might run an advanced search using "forms" in "Any field" and typing in "real estate" as the "Subject."
