Yes. Each of you can adopt the other's child, and it's often called a cross-adoption or mutual stepparent adoption. You file one adoption for each child (or each set of children) your spouse brought into the marriage. When both are finished, each of you is a legal parent of every child in the home, and the children are legal siblings. Each adoption stands on its own, so the other biological parent of each child is handled separately, and in most cases that parent never signs anything.
How a two-way adoption usually works
Two adoptions, one family. You adopt your spouse's child, and your spouse adopts yours. Each adoption has its own petition, its own consents, and its own decree. Many courts let you file both at the same time and schedule the hearings together. Some treat them as separate cases from start to finish. Your county's practice decides that.
Your spouse consents to your adoption, and you consent to theirs. Each biological parent in the marriage signs a consent to their spouse adopting their child. Families often do this at the same sitting.
Each child has a different other parent. Your child's other parent and your stepchild's other parent are different people with different histories. One may be deceased, one may have disappeared, and one may be active in the child's life and happy to sign. Each situation gets its own paperwork.
Older children have a say. Many states require a child above a certain age to consent to their own adoption. The age differs by state. Younger children are not asked to consent, but the judge may talk with them at the hearing.
Adult stepchildren can be adopted too. If one of the children is 18 or older, adult adoption is available in many states. The adult signs their own consent, and the process is usually simpler because there is no other-parent consent to resolve.
What changes from state to state
The overall idea is the same everywhere, but the details are local. These are the things that vary:
- Which court hears it. It might be a family, probate, circuit, superior, or district court, depending on the state and sometimes the county.
- Residency. Some states require the adopting parent or the child to have lived there for a set period before filing.
- Consent age for the child. The age at which a child must agree differs.
- The abandonment or non-support period. Each state sets how long a parent must have gone without contact or support before the court can treat the adoption as proceeding without their consent.
- Home study. Some courts waive it for stepparents, some require a short one, and some leave it to the judge.
- Background checks. The type and number of checks differ, and many courts ask for them on every adopting parent.
- Single filing or two. Courts differ on whether a cross-adoption goes in as one combined filing or two.
- Local forms and filing fees. Your county clerk can confirm the current fee and any local form. We prepare the package for your county.

What the court looks at, and what happens with the other parent
Courts want children to have the security of two active legal parents. A stepparent adoption gives a child that, on paper, when it's already true at home. Judges see these petitions every day, and they approve them.
For each adoption, the judge looks at a few things:
- The relationship. Is the stepparent already acting as a parent, and does the child do well in the home?
- The marriage. Is the household stable, and does the biological parent in the marriage support the adoption?
- The adopting parent. Do the background checks come back clean?
- The other biological parent. Has that parent consented, or is there a lawful reason the adoption can proceed without a signature?
Here is the part families worry about most, and they usually worry more than they need to. In most stepparent adoptions the other parent, usually the father, never signs a consent, and the judge approves the adoption anyway. Typically that parent stopped contact or support, can't be found, or has died. In our experience, about 80% of the stepparent adoptions we have completed went forward without the other biological parent's consent.
Notice and publication are routine steps, not roadblocks. If the other parent can be located, they receive formal notice of the case. If they can't be found, the court allows notice by publication after a search. We prepare those documents for your county. If a parent has died, the death certificate takes care of it.
Some other parents do sign, especially when they've stayed involved and trust the stepparent. That makes the case simpler. If a parent actively shows up to fight the adoption in court, some families choose to add an attorney for that hearing.
What changes for the children, and for you
Legal parenthood becomes complete. You can sign school and medical forms, add the children to insurance, and make decisions in an emergency without needing your spouse. If something happens to your spouse, your rights as a parent are not in question.
The children become legal siblings. That matters for inheritance, for benefits, and for the plain fact that nobody in the house is a "step" anything on paper.
The other parent's legal ties end. After the decree, that parent no longer has parental rights or duties for that child. Whether the child keeps any inheritance connection through that side of the family depends on state law.
Child support going forward ends. The duty to pay future support stops at adoption. Whether past-due support can still be collected depends on state law, so ask us if a large balance is owed.
The birth certificate is updated. After the decree, the state issues an amended certificate listing the adoptive parent. Name changes for the child can usually be requested in the same case.
What to do next
- List the other parent for each child. Note whether each is involved, out of contact, unreachable, or deceased, and when you last had contact or support.
- Gather the basics. You'll want birth certificates for the children, your marriage certificate, and any custody or support orders.
- Talk with your children. Older children will be asked to agree, and younger ones do better when they know what's coming.
- Decide if both adoptions are right for your family. Some families do both, and some do one now and one later. Doing both at the same time usually saves effort.
- Answer the questions online. We prepare the court papers for your county based on your answers.
Questions families ask next
Do the kids have to adopt each other? No. Siblings don't adopt each other. The children become legal siblings once each of you has adopted the other's child.
Can we do one adoption now and the other later? Yes. They don't have to be filed together. Many families file both at once to get everything finished on the same schedule.
What if one child's other parent is active and objects? An active, objecting parent changes the case, because the court will hear from them. We can talk through your situation by phone before you file anything.
What if the other parent is deceased? That's one of the simplest situations. You file the death certificate with the petition, and that parent's consent is no longer needed.
Does the cost double for a cross-adoption? Pricing is $349 for the first child and $99 for each additional child. Call us and we'll tell you how your family's filing counts.
