When a New Partner Starts Deciding Whether Your Child Sees You
A new partner has no automatic say over your court-ordered schedule. Learn who is responsible and how to keep a record that protects your child.

You may be comfortable with your child using social media while the other parent objects. In the United States, no federal law requires co-parents to agree about social media, so the parenting plan and your state’s custody rules guide who decides. A platform’s age requirements and your child’s readiness also shape the choice.
When the homes have different rules, your child needs clear explanations and a workable plan for each home. You can address the disagreement without asking your child to settle it.
No federal law makes two parents agree on whether their child may use social media; the parenting plan and state custody rules determine how the decision is handled.
If you share legal decision-making authority, check your court order for how it defines major decisions and how disagreements are resolved. The order may address education, health care, or other subjects without naming social media. That wording, along with state law, can affect whether a new account requires joint agreement.
If one parent has sole authority over a particular decision, the order may assign that parent the final say. Day-to-day rules in each home can still differ. Read the exact language before treating a household rule as a custody violation.
Platform age limits are a separate issue. Many services set a minimum age of 13, but that does not settle which parent gets to decide or whether an account is suitable for your child. Your child’s safety, well-being, and ability to follow the rules belong in the discussion.
If you cannot agree, use the dispute-resolution steps in your order, such as mediation if it is required or available. Keep the discussion between adults, and avoid putting your child in the role of messenger or referee.
Federal law sets privacy protections for children under 13, while platform age rules and custody orders address different questions.
The Children’s Online Privacy Protection Act (COPPA) applies to websites and online services directed to children under 13, and to services that know they are collecting personal information from children under 13. It requires covered services to provide notice and obtain verifiable parental consent before collecting, using, or disclosing that information, subject to the rule’s requirements. The Federal Trade Commission’s COPPA Rule page explains the law’s scope.
COPPA does not set a nationwide minimum age for social media, decide which parent controls an account, or require two co-parents to agree. A service’s minimum-age rule is its own platform requirement, separate from COPPA. You should check the specific service’s current terms before helping your child create an account.
Your custody order addresses parental authority. If it gives both parents joint legal decision-making, review its language and dispute-resolution process to see how disagreements are handled. If the order does not mention social media, avoid assuming that it automatically counts as either a major decision or a routine one.
State rules also differ, and laws affecting minors’ online accounts can change. For a specific dispute, read your current order and get advice from a family-law attorney in your state.
The American Academy of Pediatrics’ Center of Excellence suggests waiting until at least age 13, while recognizing that readiness differs from child to child.
Age alone does not show whether your child can manage an account safely. The AAP advises considering your child’s maturity and ability to handle online interactions. Its guidance on when to introduce social media also identifies reasons to slow down, including bullying, anxiety or depression, and difficulty following technology rules.
Use those concerns to make the discussion specific. Consider whether your child follows agreed limits, tells you when an online interaction feels upsetting, and can pause use when asked. If those skills are still developing, you can delay an account or set closer supervision.
The U.S. Surgeon General’s advisory describes potential risks to youth mental health and encourages families to consider how social media affects a young person’s well-being. You can read the HHS advisory on social media and youth mental health. Use your child’s needs and behavior to guide the timing, alongside the platform’s minimum-age rules.
Your parenting plan and state custody rules guide who decides; the answer depends on the authority your order assigns.
Start with the sections on legal decision-making, parental responsibility, and dispute resolution. If the order gives both parents shared authority over major decisions, follow its process when you disagree. If it gives one parent authority over a particular category, that language may control. A parenting plan may also leave routine household rules to each parent.
Arizona offers a clear example of why the wording matters. Its statute defines joint legal decision-making and describes the court’s role in allocating decision-making authority. Read the current Arizona statute on legal decision-making alongside your order. The statute does not name social media as a separate decision category, so your plan’s language and the circumstances of the disagreement remain relevant.
A Florida parenting plan form provides another example of how plans can address day-to-day decisions and electronic communication. It is a sample, not a rule for every state or a replacement for your own order. You can review the Florida parenting plan form, then check your state’s current form and your signed plan.
If the order is unclear, get state-specific legal advice before treating the disagreement as a violation.
A short written agreement gives you and your child clear expectations, even when each home has different rules.
Keep the plan practical and focused on what both parents can support. Include:
Write down the parts that apply in both homes, then name any household-specific rules clearly. Avoid asking your child to carry updates between parents. Send changes directly to each other and keep the child-facing explanation brief.
If you cannot agree on whether your child may have an account, pause the decision if your order allows it and use its dispute-resolution process. A temporary rule should state who supervises access and when you will review the issue.
Present a united front where you can, and explain different household rules without criticizing the other parent.
Tell your child what applies in your home in direct, calm language: “In this home, social media stays off until we agree on a plan.” Explain the reason in terms your child can understand, such as readiness, privacy, or a rule in the parenting plan.
If the other home permits access, avoid asking your child to choose sides or report on the other parent. Let your child know that you will speak with the other parent directly about changes, safety concerns, or account rules.
Keep the boundary clear and consistent in your own home. If your position changes, explain the new rule and what your child needs to do next, such as asking before opening an account or coming to you with an online concern.
