What is “Discovery” in Divorce?

The Divorce Discovery Process, in General

Discovery in divorce is the legal process in which parties can “discover” information regarding the financial information of the other party. Because an overwhelming amount of people going through the divorce process have little understanding of what marital assets they have, what marital debts they have, what their spouse’s income is and other financial information, discovery is very important and relevant to the divorce process. In parentage cases, it is expected that the vast majority of the parties involved with each other romantically do not know their ex-significant other’s financial situation.

What Types of Discovery are Used in Divorce Cases?

There are quite a few different ways to issue discovery. There are several types of written discovery as well as oral discovery, also called a Deposition. This blog is intended to outline the most popular types of discovery one may encounter in an Illinois divorce or family law matter.

Exchanging Financial Disclosure Statements

Any case in Illinois which requires the financial information of both parties typically begins with the exchange of Financial Disclosure Statements. This discovery document is a sworn affidavit which outlines a partie’s expenses, income, debts, and assets. The document must be filled out truthfully and completely, or the party completing the document could be subject to punishment or sanctions by the court. It is also encouraged that substantiating financial documents are attached to the Financial Disclosure Statement, such as pay stubs, bank statements, tax returns and W-2s/1099s.

Written Discovery: Notice to Produce Documents

There are two standard types of “written discovery” issued in family law cases. One document is called a Notice to Produce Documents. This is a written request served upon a party or their counsel requiring them to respond within 28 days. In an illinois divorce, the Notice to Produce Documents asks for years of:

  • pay stubs,
  • tax returns,
  • corporate tax returns,
  • attachments and schedules to tax returns,
  • credit card statements,
  • leases and/or mortgage statements,
  • life insurance documentation,
  • retirement account statements,
  • proof of attorney’s fees paid in a matter, and
  • other different financial documents.

Written Discovery: Interrogatories

The scope of document production requests can be extremely wide in terms of what is requested, and can seek documents that go back many years (typically 3–5, but sometimes shorter, or sometimes longer). The party who is served discovery must also respond to the actual notice, indicating what documents they are enclosing, what does not apply to them, what documents may not be in their possession or control, and the like. This helps the attorneys and parties to the case know what documents actually exist and can be subpoenaed or what they can compel the party to produce.


Depositions are a question and answer session attended by the parties, their attorney’s and a court reporter. In most family law cases, depositions last up to three (3) hours but can be extended for good cause. The scope of what can be asked in a deposition is large. Not every question asked in a deposition will be relevant at a trial. The deposition questions can be anything that may lead to relevant information or documents in a case. It is a time to ask the party questions, and typically there are a lot of questions about a party’s financial documents. This is the time to ask those questions. Thus, typically, but not always, depositions are done after formal written discovery is complete.

Requests to Admit Facts or Genuineness of Documents

“Requests to Admit Facts” and “Requests for Genuineness of Documents” are specialized discovery instruments are not often used in family court, but appear from time to time. They are described as follows:

  • A Request of Genuineness of Documents is similar to a request to admit facts, except documents are enclosed when served. If the documents are ignored, they are automatically deemed to be genuine. If some documents are not genuine or believed to be inaccurate, the party who was served with the Request must respond as such within 28 days.


Subpoenas are a formal request for documents or other forms of discovery from a specific person or entity.
