Editing Interrogatories (section)

===United States===
In the United States, use of interrogatories is governed by the law where the case has been filed. All federal courts operate under the [[Federal Rules of Civil Procedure]], which places various limitations on the use of this device, permitting individual jurisdictions to limit interrogatories to twenty-five questions per party. Interrogatories are typically "verified", meaning that the response will include an [[affidavit]] and will therefore be under oath.<ref>{{cite web|title=Federal Rules of Civil Procedure, Rule 33. Interrogatories|url=https://www.law.cornell.edu/rules/frcp/rule_33|website=Legal Information Institute|publisher=Cornell Law School|access-date=30 September 2017}}</ref> The affidavit may distinguish interrogatories from [[requests for admission]], which are not normally answered under oath.<ref>{{cite journal|last1=Feirich|first1=John C.|last2=Feirich|first2=John K.|title=Interrogatories to Parties and Demands to Admit|journal=University of Illinois Law Forum|date=1959|pages=733|url=http://heinonline.org/HOL/LandingPage?handle=hein.journals/unilllr1959&div=50&id=&page=|access-date=30 September 2017}}</ref>

California, on the other hand, operates under the Civil Discovery Act of 1986 (a revision of an older 1957 act), which is codified in the [[California Code of Civil Procedure]].  The Discovery Act allows up to thirty-five specially prepared interrogatories per party,<ref name="section2030030">[https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CCP&sectionNum=2030.030 California Code of Civil Procedure Section 2030.030].</ref> but this limit may be exceeded simply by executing and serving a declaration of necessity with the interrogatories.<ref>[https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?sectionNum=2030.040&lawCode=CCP California Code of Civil Procedure Section 2030.040].</ref><ref>[https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?sectionNum=2030.050&lawCode=CCP California Code of Civil Procedure Section 2030.050].</ref>  However, because the declaration of necessity must be executed under penalty of [[perjury]], it can expose an attorney to ''personal'' sanctions for propounding an excessive number of harassing and burdensome interrogatories.

In nearly all U.S. jurisdictions, interrogatories are called just that and are supposed to be custom-written, although many questions can be reused from one case to the next.  In the U.S. states of California, New Jersey, and Florida, the courts have promulgated standard "form" interrogatories.  In California these come on an official court form promulgated by the [[Judicial Council of California]]<ref>[https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CCP&sectionNum=2033.710 California Code of Civil Procedure Section 2033.710].</ref> and a party may ask another party to answer any of them by checking the appropriate boxes.<ref name="section2030030" />  The advantage of the California form interrogatories is that they do not count against the limit of 35<ref name="section2030030" /> (except when used in limited civil cases); the disadvantage is that they are written in a very generic fashion, so about half of the questions are useful only in the simplest cases.  In turn, California calls custom-written interrogatories "specially prepared interrogatories."<ref name="section2030030" />

Because interrogatories are so heavily used in American discovery, there are two major compilations of generic interrogatories covering almost every conceivable type of legal case: ''Bender's Forms of Discovery: Interrogatories'' (published by [[LexisNexis]]) and ''Pattern Discovery'' (published by [[West (publisher)|West]]).
