Evidence in Illinois Domestic Violence Cases
Why Evidence Matters
Evidence can help courts and other decision-makers better understand what has been happening in a relationship. In Illinois, careful documentation may be important in cases involving Orders of Protection, criminal charges, or family law matters such as parenting time and decision-making responsibilities.
This page offers general information only. It is not legal advice. Laws and court practices can change, and they may be applied differently depending on your situation.
Types of Helpful Evidence
Not every situation will involve all of these items, and it is not necessary to gather anything that would put you at risk. When it is safe to do so, people sometimes collect:
Communications
- Text messages, emails, and messaging app conversations (screenshots or exports)
- Voicemails or call logs showing frequent or threatening contact
- Social media messages or posts that show threats, harassment, or attempts to control
When possible, including dates, times, phone numbers, and usernames can make this information clearer to the court.
Photos and Videos
- Photos of visible injuries or damaged property
- Images of threatening notes, messages, or written materials
- Photos of the scene after an incident (for example, broken objects or visible damage)
Timestamped photos or device metadata can sometimes help show when pictures were taken, but this is not required for them to be useful.
Witness Statements
- Statements from people who saw or heard incidents
- Accounts from neighbours, friends, family members, or coworkers who observed controlling or threatening behaviour, injuries, or emotional impact
- Testimony from service providers who have direct observations, such as shelter workers or support workers, where appropriate
In court, witnesses may need to testify in person or by another permitted method. Written statements alone may not always be enough, but they can help your lawyer or legal aid provider prepare.
Medical and Health Records
- Emergency room or clinic visit notes after an incident
- Doctor, nurse, or other health provider records describing injuries or fear for safety
- Prescriptions or treatment plans related to injuries or stress linked to abuse
Accessing and sharing health records can have privacy implications. It is generally helpful to talk with an Illinois lawyer or legal aid advocate about what to request and how to use it.
Police and Court Documents
- Police reports or incident numbers from calls for assistance
- Copies of prior Orders of Protection, bond conditions, or no-contact orders
- Charge documents, court minutes, or judgments from related criminal or family proceedings
Even if police did not lay charges, the fact that a report was made can still be relevant in some cases.
Keeping a Timeline or Journal of Incidents
A simple, factual record can help you remember details later and assist a lawyer or legal aid advocate in preparing your case. Some people choose to record:
- Dates and approximate times of incidents
- What was said or done, in brief, neutral language
- Who was present or might have witnessed the incident
- Any injuries, medical visits, or work/school impacts
- Whether police were called or other services were contacted
It can be safer to avoid highly emotional or speculative language and stick to what happened, when, and who was involved. This can make the information clearer if it is used later in court.
Safe Storage of Evidence
Safety and privacy are more important than collecting evidence. If saving evidence could increase the risk of harm, it may be safer not to keep it or to ask a trusted person or professional about options.
Digital Safety Strategies
- Use a password or PIN that is not easily guessed, and avoid sharing it.
- Consider using a separate email account that is not logged in on shared devices.
- Store copies of screenshots or files in secure cloud storage rather than only on a shared phone or computer.
- Regularly review “sent,” “deleted,” and “recently deleted” folders to make sure nothing appears that could draw attention.
Physical Storage Strategies
- Keep printed documents, photos, or journals in a locked drawer, box, or safe if available.
- Store copies with a trusted person outside the home, such as a friend, family member, or advocate, if this feels safe.
- Avoid obvious hiding places that someone is likely to search, such as under a mattress or at the back of a closet.
How Evidence May Be Used in Illinois Cases
Orders of Protection Hearings
In Illinois, evidence can help a judge decide whether to issue or extend an Order of Protection and what specific protections to include. Depending on the situation, documents or testimony might be used to show:
- A pattern of threats, harassment, or physical harm
- Fear for safety of yourself or children
- Past incidents, even if they were not reported right away
Courts may accept different forms of evidence, and judges have discretion to decide what weight to give each piece. A lawyer or legal aid advocate can help you understand what the court in your county generally expects.
Criminal Matters
When criminal charges are involved, evidence is usually handled according to strict court rules. Law enforcement and prosecutors may use:
- Photos, medical records, and witness statements collected after an incident
- Recordings or messages, if lawfully obtained
- Reports of prior incidents or violations of orders
If you are a survivor involved in a criminal case, or if you have been charged, it is especially important to speak with an Illinois criminal defense or victim rights lawyer about how any evidence you hold could affect the case.
Custody and Parenting Time Disputes
In family law matters, Illinois courts focus on the best interests of the child. Evidence of abuse or controlling behaviour may be relevant to:
- Decision-making responsibilities
- Parenting time schedules
- Safety conditions for exchanges and communication
Judges may look at patterns over time rather than single events. Documentation that shows how the situation has affected children’s safety or well-being can be important, but it is wise to discuss what to share with a family law attorney or legal aid office first.
Recording Someone Without Their Knowledge
Illinois law places limits on recording private conversations. Secretly recording another person without consent may violate state or federal law in some situations and could affect your safety, your case, or your own legal exposure.
Before recording phone calls, in-person conversations, or video or audio inside a home, it is important to speak with an Illinois lawyer about what is permitted. A local attorney can explain how state and federal recording laws apply to your specific circumstances.
Working With Legal Aid and Attorneys
Choosing what evidence to collect and how to present it can be complicated. A lawyer or legal aid advocate can:
- Help you prioritize safety while gathering and storing information
- Explain which types of evidence are most useful for your situation
- Prepare you and any witnesses to explain documents and events clearly in court
- Advise you about privacy, confidentiality, and possible risks of sharing certain information
If you do not have a lawyer, you may be able to get free or low-cost help from a legal aid organization in Illinois or from a domestic violence advocacy program. Some national-level resource lists, such as those referenced at https://www.dv.support, may help you locate services that operate in your state.
Whenever possible, try to consult an attorney before filing documents or handing over original evidence, so you can understand how it may be used and what alternatives might exist.
