LGBTQ Family Rights in Illinois

 Posted on April 25, 2026 in Family Law

Over a decade ago, same-sex marriage was legalized in Illinois, though civil unions were permitted before then. The state continues to have some of the strongest legal protections for LGBTQ families in the country. Whether you're planning to marry, start a family, or protect a family you've already built, the law is on your side. Life’s circumstances are unpredictable, though. Knowing the legislation before emergencies come up can be a great help.

If you have questions about your family's legal footing in 2026, a Wheaton LGBTQ family law attorney can help.

What Are the Marriage Rights of Gay Couples in Illinois?

Illinois was ahead of the curve on marriage equality. The state passed the Religious Freedom and Marriage Fairness Act (750 ILCS 80/) in 2013. This made same-sex marriage legal before the U.S. Supreme Court's ruling in Obergefell v. Hodges made it legal nationwide. Today, same-sex couples or queer-identifying couples in Illinois have the same marriage rights as any other couple. In fact, the Illinois Human Rights Act explicitly prohibits discrimination based on gender identity. This means access to all the state and federal protections that come with marriage, including:

• The right to file joint tax returns
• Spousal inheritance rights
• Hospital visitation and medical decision-making rights
• Eligibility for a spouse's health insurance and employee benefits
• Protections under Illinois divorce law if the marriage ends

If you were in a civil union before marriage equality became law, it is still recognized and carries many of the same state-level rights. However, civil unions don't provide the same federal protections as marriage. If you're in a civil union and want access to these legal protections, legal marriage is the way to get them.

Does Illinois Have Laws About Surrogacy for Same-Sex Couples?

Illinois doesn’t have any laws specifically about surrogacy for LGBTQ+ couples. It does have general laws intended to protect the relationships between the intended parents and child. The Illinois Gestational Surrogacy Act allows intended parents to establish parental rights before a child is even born. This is done with a document called a pre-birth order. If you're planning to use a surrogate or assisted reproduction, working with an attorney early in the process is the best way to make sure everything is legally sound from the start.

How Does Illinois Law Handle LGBTQ+ Parental Rights?

Illinois law recognizes several paths to legal parenthood for LGBTQ+ couples.

When a Child Is Born During a Marriage

Under the Illinois Parentage Act, when a child is born to a married couple, both spouses are presumed to be the child's legal parents. This applies equally to same-sex married couples. If you and your spouse are married at the time your child is born, both of you should be recognized as legal parents under Illinois law.

When a Couple Is Not Married

If you're not married, the non-biological or non-gestational parent doesn't have automatic legal status. In that situation, it's important to establish legal parentage proactively. Illinois law allows for a Voluntary Acknowledgment of Parentage to be signed at birth, declaring both people the parents. Courts can also make parentage determinations.

Second-Parent Adoption

One of the most reliable ways for a non-biological parent to secure their legal relationship with a child is through second-parent adoption. This process, similar to stepparent adoption under the Illinois Adoption Act (750 ILCS 50/), allows a parent's partner or spouse to legally adopt the child without the other parent losing their rights. Afterwards, both members of the relationship are recognized as legal parents.

Second-parent adoption is especially worth considering if your child was born before your marriage or if there's any chance your parentage could be challenged in the future.

What Happens to Parental Rights in Illinois if a Gay Couple Separates?

If a same-sex married couple divorces in Illinois, the divorce process works the same way it does for any other couple. Courts divide marital property, may award maintenance, and, where children are involved, make decisions about parental responsibilities and parenting time based on the best interests of the child.

"Parental responsibilities" refer to decision-making authority over things like education, healthcare, and religious upbringing. Parenting time is the scheduled time each parent has with the child. The same standards apply across the board, regardless of the couple’s gender or sexual orientation.

The situation gets more complicated when a couple isn't married, and only one person is a legal parent. If the non-legal parent has been acting as a parent but has no formal legal status, they may have limited rights if the relationship ends. This is one of the biggest reasons to address parentage legally while the relationship is intact.
