Can a Parenting Plan Include Rules About New Partners in Washington State?

Divorcing parents can include rules about new dating partners in the parenting plans they create as part of the Washington divorce process. Learn more about your options today by enlisting the support of an experienced and caring Seattle family law attorney.

Every divorce poses its own set of challenges. Even couples who have only been married for a year or so and who mutually agree that ending their marriage is the best path forward face a series of decisions, negotiations, and tasks before the divorce can be finalized. The marriage dissolution process becomes more complicated when the parties are parents, as they must establish a parenting plan that protects their child’s best interests and ensures that they will be supported and cared for once the divorce is granted. In Washington state, divorcing parents can work together to establish the terms of the parenting plan and then present it to the court for approval. In more contentious cases, the court can take an active role in setting the terms of the parenting plan, such as deciding with whom the child will reside and for how long. Generally speaking, the court favors parenting plans that allow the child to spend quality time with both parents, as parental involvement can boost a child’s educational performance and minimize the potentially negative impacts of divorce (i.e., anxiety, depression, behavioral struggles, etc.). However, if there are any concerns that a parent may be unfit or pose a safety threat to the child’s well-being, the court will step in to protect the child’s best interests as much as possible.

As you approach the divorce process in Washington state, it’s natural to feel somewhat intimidated by the seemingly endless decisions you need to make before you can move on to the next chapter of your life. Taking the time to establish a parenting plan can be challenging, especially if you and the other parent disagree or struggle with open and honest communication. Enlisting the guidance of a highly experienced and caring Seattle family law attorney can give you the support and confidence you need to move through this process with greater ease and understanding. You can explore how to customize the parenting plan so that it sufficiently addresses your concerns and protects your child’s best interests as much as possible. Let’s take a closer look at some of the strategies you can use when introducing a new partner after divorce and how to integrate rules for dating into parenting plans so that you, your ex, and your child are prepared for what may lie ahead. 

Understanding Washington Parenting Plan Guidelines

A parenting plan is “a court order that says who has the right to spend time with and make decisions for a child.” The form is available online so that those who are moving through the divorce process can access it, fill it out, and then file it with the court. The form asks for detailed information about each party, any safety concerns one parent may have about the other, plans for how the parties will resolve disputes that may arise in the future, parenting time schedules, and other important details. It’s worth noting that divorcing parents can add other information to this form, especially if the added provisions take a proactive approach to minimizing conflict and prioritizing the safety and best interests of the child. For instance, if you are concerned about custody agreements and new partners, you can include some ground rules for introducing new romantic partners to your child safely and appropriately to minimize conflict. It’s important to recognize that the court will only impose restrictions on parenting plans and new relationships if there are genuine safety risks to the child, but the parents can include some basic rules and considerations as part of the parenting plan if they are hoping to mitigate potential conflicts later on.

Including Clauses That Concern New Relationships After Divorce

As a parent, the thought of your ex starting to date again or entering into a new long-term relationship can be daunting. Picturing your child interacting with your ex-spouse’s new romantic partner can be upsetting and emotional. It’s important to recognize that feeling emotionally threatened by an ex-spouse’s new dating partner is understandable, but it does not in itself provide a legal justification for the court to modify the terms of an existing parenting plan. However, you can address a few ground rules for introducing your child to new romantic partners when you establish the parenting plan. For example, you may decide to include provisions that address concerns about overnight guests, cohabitation, and how your child will be introduced to new partners. Sometimes, working through these scenarios with your ex-spouse as you focus on drafting the parenting plan can improve your communication and ease your anxiety about these matters. When one of you begins dating someone new, you can use the guidelines you included in your parenting plan to ease this transition and slowly incorporate this new person into your lives.

When Will Washington Courts Enforce the Parenting Plan?

For the most part, the court encourages the separating parties to set the terms of their divorce (including the parenting plan) themselves. In the event of a dispute, the judge will take a more active role in shaping the outcome. The court will also step in whenever there are safety risks involved, as the court’s top priority is to protect the best interests and welfare of children. This means that if a parent is worried that their ex-spouse’s new partner poses a safety risk to the child, they can share these concerns with the court. The court will investigate these claims and determine whether to limit the other parent’s custody or visitation schedule because their new partner has a history of domestic violence, substance abuse, or a criminal record that poses a threat to the child. If there is credible evidence that a new dating partner poses a risk to the child’s safety, the court may limit the parent’s custodial or visitation rights to keep the child’s physical and emotional safety as protected as possible. To learn more about the court’s role in enforcing the terms of a parenting plan, consider discussing your concerns with a highly qualified and dedicated Seattle divorce lawyer today. 

How to Propose or Modify the Terms of a Parenting Plan in Washington State

It’s worth noting that a judge in Washington state will not limit a parent’s custody or visitation rights just because they begin dating a new romantic partner. The only reason why a court would step in is if there were legitimate safety concerns about a new partner interacting with the child. If you know that your ex-spouse’s new dating partner has a history of substance abuse or has been arrested for domestic violence in the past, you can raise these concerns with your dedicated Seattle family law attorney and identify the most strategic course of action. You may petition the court to modify the terms of the existing parenting plan in order to prevent your child from interacting with your ex-spouse and their new partner. For instance, you can ask the court to limit your child’s contact with this individual (i.e., preventing your ex from having your child overnight when the new partner is in the home). In some cases, the court may order supervised visitation when your child spends time with the other parent and their romantic partner out of an abundance of caution for your child’s safety and well-being. The court may also impose other types of protective measures to further ensure that the safety of your child remains the top priority.

Balancing Co-Parenting Rights and Boundaries

Raising your child after a divorce poses its own set of challenges. It can be difficult when you and your ex have different parenting styles and priorities, and the emotional ups and downs of shuttling your child between homes can be exhausting. However, as much as you may wish that you could be your child’s sole parent, it’s essential to recognize that your child has the right to spend time with both of their parents. Even if you disagree with the parenting choices that your ex is making, they have the right to care for and spend time with the child. When a new dating partner enters the picture, this can be an anxious time for you and your child. While the presence of an ex-spouse’s new romantic partner in your child’s life can be upsetting and emotionally complicated, it’s important to understand that this new chapter is natural and can be navigated relatively smoothly. When you and your ex have taken the time to set ground rules for integrating a new dating partner into your child’s life, this proactive approach can ease this transition and minimize stress and conflict. For instance, setting ground rules like only introducing the child to a new romantic partner after several successful dates (and with the other parent’s consent) can reduce confusion and anxiety for all parties involved.
