Some couples want more than a settled outcome from their separation agreement — they want privacy about the details, and an understanding that neither person will badmouth the other publicly, to family, or online. That's what a confidentiality clause and a non-disparagement clause are built to do, and while they often appear together in an Ontario separation agreement, they cover different things and come with different limits on how far they can actually reach.

This guide explains what each type of clause typically restricts, why couples include them, and where they tend to run into enforceability problems.

What These Clauses Typically Restrict

Why Couples Include Them

How Enforceable Are These Clauses, Really?

Confidentiality and non-disparagement clauses are contract terms, and like any other term in a domestic contract, they're only as strong as the agreement itself — subject to the same requirements around writing, signature, and witnessing, and the same general contract principles that can make any clause vulnerable if it wasn't properly negotiated.

In practice, financial confidentiality tends to be more straightforward to apply than a broad non-disparagement promise. A non-disparagement clause that's written too broadly can run into real tension with things it can't actually override:

Where These Clauses Commonly Run Into Trouble

What a Well-Built Clause Includes

  1. A clearly defined scope — what information is confidential, and to whom disparagement restrictions apply
  2. Carve-outs for legal proceedings, professional advisors, and legally required disclosures
  3. Carve-outs for reasonable communication about parenting between the parties, schools, and healthcare providers
  4. A defined, realistic consequence for breach, rather than a vague statement that the clause is "binding"
  5. Clear treatment of social media specifically, since this is where breaches most often happen in practice

Frequently asked questions

Can a confidentiality clause stop my ex from telling their new partner what I pay in support?

It can be written to restrict that kind of disclosure, but enforcement in practice can be difficult, and overly broad restrictions on ordinary conversation are harder to enforce than restrictions on public or written disclosure of specific figures.

Does a non-disparagement clause mean I can never mention my ex to our child's teacher?

No — a well-drafted clause should carve out honest, necessary communication with a child's school, healthcare providers, or others involved in parenting, since restricting that entirely could work against the child's interests rather than protect them.

What happens if someone breaks a confidentiality clause?

That depends entirely on what the agreement itself says the consequence is. A clause with no defined remedy is much harder to act on than one that spells out what happens, which is why vague, boilerplate confidentiality language is a common weak point.

Can these clauses stop someone from reporting a genuine child protection concern?

No. A legal duty to report a child who may be in need of protection isn't something a private agreement can override, regardless of how broadly a confidentiality or non-disparagement clause is written.
