If you've looked closely at an older separation agreement or parenting order, you may have come across a clause restricting when — or whether — a new romantic partner can meet the children or stay overnight during parenting time. These are sometimes called "new partner" clauses, and they raise a fair question: are they still enforceable, or are they a holdover from an earlier way of doing family law?

This article explains what these clauses typically say, how Ontario courts approach them today, and what to do if you're negotiating one now or trying to change one already in place.

What a "New Partner" Clause Usually Says

These clauses are negotiated terms, not something imposed automatically — they appear because one or both parents asked for them when the agreement or order was made. Common versions include:

Where These Clauses Come From

Many of these clauses reflect an earlier period in family law practice, when agreements leaned more heavily on general ideas about stability and personal conduct rather than a strict, individualized best-interests analysis. Some agreements still carry this kind of language today simply because it was copied from an older template, not because it reflects current thinking about what actually protects a child.

Are They Still Enforced? Courts' Modern Approach

Ontario's parenting framework is built around the best-interests-of-the-child test — not around policing an adult's personal life. Courts today are generally cautious about enforcing a blanket restriction on a parent's relationships unless there's a demonstrated connection to the child's well-being. A clause that mainly reflects one parent's discomfort with the other's dating life, without evidence of any risk to the child, tends to carry less weight than a clause tied to a specific, child-focused concern.

That doesn't mean these clauses are automatically unenforceable — an existing order or signed agreement remains valid until it's changed. But if the issue reaches a judge, expect the focus to land on whether the restriction genuinely serves the child, not on whether it feels fair between the adults.

When Restrictions Are More Likely to Hold Up

When Restrictions Are Less Likely to Hold Up

Negotiating, Modifying, or Removing a Clause

  1. Review the exact wording of your order or agreement — vague language ("appropriate notice") is interpreted differently than specific language ("no overnight stays during parenting time").
  2. Document why a change makes sense, whether that's the passage of time, a stable new relationship, or the clause simply never having been necessary.
  3. Try negotiation or mediation first. Many of these clauses were drafted early in a separation, when trust was low; revisiting them once things have settled is often easier than expected.
  4. Formalize any change in writing. An informal understanding between parents can quietly evaporate; a signed amendment or updated agreement protects both sides.
  5. Bring a motion to change only if needed. If the other parent won't agree and the clause is genuinely causing a problem, a lawyer can advise whether a court application is warranted.

Frequently asked questions

Can I be found in contempt for breaking a "new partner" clause?

Potentially, yes — if the clause is part of a court order and you don't follow it, the other parent can raise it with the court. Whether that leads to a real consequence depends on the specific facts and how serious the breach is. Don't assume an outdated-feeling clause is automatically toothless.

Do these clauses still get included in new agreements?

Some parents still ask for them, particularly when a separation is recent and trust is low. Whether it's the right term for your situation is worth discussing with a lawyer, since overly broad restrictions may be difficult to enforce later.

What's the difference between a "notice" clause and a "restriction" clause?

A notice clause typically requires telling the other parent before introducing a new partner to the child; a restriction clause goes further, actually limiting overnight stays or contact. Courts generally view narrower, notice-style terms as easier to justify than outright bans.

Can a "new partner" clause be added after the original order or agreement was signed?

Yes — either by both parents agreeing to change their agreement, or through a motion to change if one party is asking a court to add or modify a term in an existing order.
