Co-Parenting With Your Ex and Their New Partner (Or Yours)

Bringing a new partner into your life is a big step post divorce — especially when you're co-parenting with your ex.

Setting boundaries for new partners when it comes to your children is important. You'll also need to set some ground rules for co-parenting with your ex and their new partner.

Establishing the role of new partners in your child's life

Co-parenting when your ex has a new girlfriend or another partner is tricky. The person will be part of your child's life, but how involved can they be in raising the child?

It's best to plan ahead for new relationships you might have in the future. When negotiating a parenting plan, or creating a plan proposal, specify whether new partners are allowed to:

• Pickup or dropoff your child for visits
• Stay overnight when the child is visiting
• Watch the child when the other parent isn't available
• Discipline your child
• Make decisions for the child (explain which decisions)
• Attend the child's extracurriculars and family gatherings
• Post about your child on social media

Even if you already have a custody order, it's possible to request a modification to add these terms.

Get professional help if you're struggling to have conversations about integrating a new partner into your child's life. Mediators can help you talk through your differences while parenting coordinators can be the decisive voice when you can't agree. Consider therapy if new partners cause resentment.

When a new partner is interfering with parenting

While new partners are often positive and supporting presences in a child's life, this is not always the case. Some new partners feel jealous that their partner regularly contacts their ex — even if they only talk about parenting. They might try to control conversations between the co-parents, convince their partner to deny the co-parent's rightful parenting time or act in a parental role without legal authority or parents' permission.

Whether it's a girlfriend interfering with parenting or another partner, you can go to court if their meddling hurts your ability to parent. You could request that the court change the custody order to give you more time to make up for what you've been deprived of. You might also ask for the court to bar the new partner from pickups and dropoffs if they are confrontational during them.

You'll need strong evidence to support your case, like:

• The new partner's history of crime, violence or substance abuse
• Significant changes in your percentage of parenting time
• Audio from phone calls (if allowed in your jurisdiction)
• Messages exchanged between you and the partner
• Social media posts

If you want to avoid the expense of court, find other ways to keep new partners out of co-parenting matters.

• Communicate through an app like Custody X Change to keep conversations civil and only between you and your co-parent.
• Bar the new partner from contacting the co-parent.
• Don't bring your new partner to events the co-parent is attending.
• Don't involve the new partner in co-parenting discussions.

What you can do to preserve your co-parenting relationship

Co-parenting with your ex and new partners isn't easy, but you don't have to give up on co-parenting. Try the following strategies to keep your co-parenting relationship strong.

Always prioritize your children

When your focus is on your kids, it's easier to shut out any negativity coming from a co-parent or their new partner. Don't allow a new partner's rejection of you to impact your relationship with your kids. Continue to co-parent as you were before the new partner was in the picture. Once they stick around for longer, you can begin making changes to include the new partner in your child's life.

Move on from your ex

Redefining your relationship with your ex is a key component of a successful co-parenting relationship. Let go of lingering feelings from your relationship and focus on co-parenting. This could also help you have a more positive relationship with your or your ex's new partner — you won't harbor jealousy or ill-will.

Slowly integrate your new partner into the equation

It's a common courtesy to introduce your new partner to your co-parent before your children. You'll also want to make sure this is someone you can see yourself being with long-term; frequently introducing your child to different partners may overwhelm or confuse them.

Ease your child — and your new partner — into the dynamic. Start with a brief introduction. When they first begin spending time together, do fun activities so there's less pressure to make conversation. Adjust until everyone is comfortable. Encourage your child to develop a relationship with your new partner, but don't force it.

Don't rush to give your new partner a parental role

Make sure your partner respects the current co-parenting dynamic. You might eventually live together or marry but early on in the relationship, your new partner should take a backseat. Don't let them discipline your child or dictate how you parent, and don't make your child address your new partner as "mom" or "dad." Your child should respect them as an adult but they are not required to treat them like a parent.

Mind how your new partner treats your ex

When your new partner is disrespectful toward your ex — even on social media — tell them it's not okay. Your co-parent may take continued disrespect as proof you condone your new partner's behavior and support their hurtful opinions. This could fracture your co-parenting relationship. Even if your new partner dislikes your ex, they should respect your co-parent's role as the other parent of your child.

Planning for new relationships

Including rules for co-parenting with your ex and new partners in your parenting plan will save you time when the issue arises.

Unfortunately, figuring out how to put your rules into airtight legal language can feel overwhelming.
