The A–Z of a Child Support Demand Letter

The five-second version: The other parent has stopped paying. Before you go to court — expensive, slow, adversarial — there's a step that often works on its own: a formal child support demand letter. It states what's owed, on what basis, by when, and what happens if it isn't paid. It's calm, it's factual, it creates a dated record, and it frequently gets payment moving again without anyone filing anything. LegalDoc's Child Support Demand Letter gives you the structure.

Now the long version.

The messages stopped working months ago. "Please, the children's school fees are due." Read. No reply. "This isn't about us, it's about them." Read. Nothing.

There's a point where polite reminders have clearly run their course, and the next real option feels like court — which is expensive, slow, and turns a strained co-parenting relationship into open war. Most people freeze right there, stuck between a WhatsApp message that's being ignored and a lawsuit they can't face.

There's a step in between, and it works more often than people expect: a formal demand letter.

What a child support demand letter is

A child support demand letter is a formal, written, dated notice from you to the other parent, stating that child support is owed, setting out the amount and the basis for it, giving a clear deadline for payment, and spelling out the consequences if the deadline passes.

It's not an angry message and it's not a lawsuit. It sits deliberately between the two — more serious than a reminder, less drastic than litigation. And that middle position is exactly why it works.

Why it often succeeds where messages failed

A demand letter changes the dynamic for three reasons.

It signals that you're serious. A casual WhatsApp is easy to ignore; a formal letter, especially one referencing the possibility of court, is not. It creates a paper trail — a dated record that you demanded support and gave a fair chance to comply, which becomes your first exhibit if the matter ever does reach a court. And it usually reaches the other parent's more rational self, or their adviser: someone who reads the letter and says, "just pay this, because the alternative is worse and more expensive."

Many child support disputes settle at exactly this stage, without anyone filing anything, precisely because the letter makes the cost of continued non-payment suddenly concrete.

What it should contain

A demand letter that works includes the essentials, plainly stated: who the parents are and who the child is; the basis of the obligation — a prior child support agreement, a court order, or simply the legal duty of a parent to maintain their child; the amount owed, with a clear breakdown if arrears have built up; a clear deadline, typically 7 to 14 days from the date of the letter; and the consequence of non-payment — that you'll pursue the matter through the appropriate court to enforce the child's right to maintenance.

The tone matters as much as the content. Factual, calm, firm. State what's owed and what happens next; leave the anger out. A letter full of insults or wild demands does the opposite of what you want — it can be used against you, and it makes settlement harder.

The legal footing behind it

The letter isn't a bluff, and that's what gives it force. Nigerian law recognises the child's right to maintenance — under the Matrimonial Causes Act for children of a marriage, and under the Child's Rights Act more broadly, with the child's best interests as paramount. The duty to maintain a child rests on parenthood, regardless of whether the parents were ever married. So when your letter says you'll enforce the child's right to support through the courts, that's a real and available route, not an empty threat.

How to deliver it

Deliver it in a way you can prove. Email to the other parent's known address, with the letter attached. A messaging app they actually use, keeping the delivery and read confirmations. And, ideally, a hard copy delivered with acknowledgement or by tracked courier. Keep proof of every method — that proof is what turns "I asked" into "I formally demanded, on this date, and can show it."

What happens if it's ignored

If the deadline passes and nothing changes, you've lost nothing — you've gained a documented, good-faith attempt to resolve matters, which strengthens your position. The next step is usually a formal application through the appropriate court (the Family Court or the relevant court with jurisdiction over maintenance), where the child's right to support is enforceable. Your demand letter, with proof of delivery, is the evidence that you tried the reasonable route first.

Keep the child at the centre

Throughout, frame everything around the child, not the grievance between the adults. It's not "you owe me money." It's "our child is entitled to support, this is what's owed, and here's what needs to happen." That framing is both more effective — it's harder to argue with — and truer to what the law is actually protecting.

Frequently asked questions

Do I need a court order before sending a demand letter?

No. You can send a demand letter based on an existing child support agreement, a prior court order, or simply the legal duty of a parent to maintain their child. The letter often resolves things before any court involvement is needed.

Will a demand letter actually work?

Often, yes. A formal, dated letter referencing possible court action changes the dynamic that a WhatsApp message can't — it signals seriousness, creates a record, and usually prompts the other parent (or their adviser) to pay rather than face a more expensive alternative. Many disputes settle at this stage.

What should the deadline be?

Typically 7 to 14 days from the date of the letter. Shorter than a week can be argued to be unreasonable; much longer weakens the sense of urgency. Two weeks is a fair, defensible window.

Does it matter that we were never married?

No. The duty to maintain a child rests on parenthood, not on the parents' relationship. An unmarried parent owes support, and the letter can be based on that duty directly.

How should I deliver it?

By email, by a messaging app they use (keeping read confirmations), and ideally a hard copy with acknowledgement or tracked courier. Keep proof of every method — it's what lets you show you formally demanded payment on a specific date.

What if they still don't pay?

You've lost nothing and strengthened your position. The next step is a formal application through the appropriate court, where the child's right to maintenance is enforceable, and your demand letter (with proof of delivery) shows you tried the reasonable route first.

Should the letter be angry?

No — calm and factual is far more effective. State the basis, the amount, the deadline and the consequence, and keep it centred on the child's entitlement rather than the conflict between the adults. Angry letters can be used against you and make settlement harder.
