Blended families

Co-parenting with an ex when there is a new partner in the picture

In a stepfamily, the former partner does not leave the family. They stay connected through the children, and every new marriage has to make room for that relationship without letting it take over.

How do you co-parent with an ex in a blended family?

Co-parenting with an ex in a blended family works best when the two parents keep a businesslike, child-focused relationship and the new partner supports it from the side rather than in the middle of it. The aim is not friendship, though some former partners manage that. It is predictable, respectful contact about the children, kept away from the children's ears.

This matters because the other parent remains part of the family whether anyone likes it or not. Psychologist Patricia Papernow lists ex-spouses, the other parents outside the household, as one of five major challenges stepfamily structure creates. The new marriage cannot pretend the former one did not happen, because the children carry both.

Keep the children out of the middle

The American Academy of Pediatrics, in guidance for parents after separation, is clear on a few points that apply just as much once a parent remarries.

  • Do not make your child the messenger. Scheduling, pick-ups and money should go directly between the adults.
  • Talk about disagreements with the other parent in private, where the child cannot overhear, including calls and texts.
  • Do not criticize the other parent in front of the child.
  • Never ask a child to take sides. Children have loyalties to both parents.
  • Where possible, agree on consistent rules for both households.

Former partners relate in different ways

University of Georgia Extension summarizes the work of Constance Ahrons and Roy Rodgers, who described five kinds of relationships between former spouses. At one end, "perfect pals" stay friendly and help each other with the children; the extension writers note this is rare. "Cooperative colleagues" may not like each other but keep conflict under control for the children's sake. "Angry associates" and "fiery foes" stay locked in anger, and the children are often caught in the middle. "Dissolved duos" lose contact altogether.

The most useful point in that summary is that the main difference between these types is how conflict and anger are handled, not whether conflict exists. Many co-parents will never be pals. Cooperative colleagues is a realistic and worthwhile goal.

What helps co-parenting go more smoothly?

The UGA guidance offers practical suggestions for dealing with a former spouse. Adapted, they include these.

  • Set clear rules for how you communicate. Some co-parents need a very fixed structure, such as messages only through one channel; others can be more flexible.
  • Do not try to change your ex. Focus on your own behavior and responses. Trying to control the other parent tends to leave you frustrated.
  • Be respectful and keep it about the children. Treat the other parent with the courtesy you would show a stranger, and do not expect details of their private life.
  • Keep agreements and appointments. Be on time for exchanges, and if you cannot keep a commitment, say so and why.
  • Be flexible about schedules, holidays and vacations, especially as the children's needs change with age. Holidays and custody schedules goes into the calendar side.

Where does the new partner fit?

For most stepparents, the role with their partner's ex is supportive and quiet: polite at exchanges, not a go-between, not a second front in old conflicts. Co-parenting decisions are usually best made between the two parents, with the stepparent's views going into the couple's private conversation rather than directly to the ex.

That can be hard. A stepparent may feel the ex has too much influence over their household, or see the ex's choices affecting stepchildren they care about. Those feelings are worth taking seriously with your partner. Protecting your marriage in a blended family looks at keeping the couple steady when an ex is a source of strain.

For the parent, a new marriage can stir the old relationship too. Grief, guilt or anger from the divorce can resurface when the ex remarries, or when your own new partner and your ex meet. Life after divorce covers that wider transition.

Custody disagreements and the legal side

Custody, visitation and child support are legal matters, and this page is not legal advice. For questions about your rights or your custody order, talk to a family law attorney licensed in North Carolina.

It may help to know that the North Carolina Judicial Branch runs a Child Custody and Visitation Mediation Program. Once a custody case is filed, parents are generally required to attend mediation unless a judge waives it, and abuse by the other party is one of the listed reasons a judge may do so. The mediator does not decide the case; their role is to help the parents reach a written parenting agreement if they can.

When the other parent is unsafe

Everything above assumes both parents are safe to deal with. If a former partner threatens, harasses or frightens you, or you are worried about the children's safety in the other home, co-parenting tips are not the answer. Talk to an attorney, and contact the National Domestic Violence Hotline (1-800-799-7233, or text START to 88788). In an emergency call 911, and if you or a family member is in crisis, call or text 988.

Common questions

Should my new spouse communicate with my ex?

Usually it works best if the two parents handle co-parenting directly and the new spouse stays courteous but out of the middle. Some families do well with more contact once things are settled, for example around shared events. If the relationship between your spouse and your ex is tense, keeping logistics between the parents tends to lower the temperature for everyone, including the children.

What if my ex badmouths me or my new partner to the kids?

You cannot control what the other parent says, and responding in kind usually puts the children further into the middle. What you can do is avoid criticizing the other parent yourself, reassure the children that they are allowed to love both parents, and raise the issue directly with your ex in private. If it escalates or affects the children's welfare, talk to a family law attorney.

Does the stepparent have any say in co-parenting decisions?

Legally, custody decisions belong to the parents and the court, and an attorney can explain what that means in your situation. Within the household, a stepparent's views matter and belong in the couple's private conversations. Most families find it works better when the parent then takes those agreed positions to the other parent, rather than the stepparent negotiating with the ex directly.

Can counseling help with co-parenting stress?

Counseling can help a parent or stepcouple manage the stress, anger or grief that co-parenting stirs up, and plan how to handle contact with an ex calmly. Laura Bass works with adults in Charlotte, including parents and stepparents. She does not give legal advice or take part in custody decisions.
