Are you raising children on your own, or have you recently gone through a separation? You may be entitled to extended child benefit — an important financial support for single parents that many don't know about or fully understand.

Extended child benefit is a supplement to the standard child benefit payment and can provide significant extra income each year. This guide gives you a complete overview of who qualifies, how the benefit works, how to apply, and what the rules are for shared custody arrangements.

What is extended child benefit?

Extended child benefit is a financial supplement from social services for single parents. Its purpose is to help cover the extra costs that a single mother or father faces when raising children alone.

The benefit is paid in addition to the standard child benefit that all parents with children under 18 receive. This means that as a single parent, you receive both the standard child benefit and the extended child benefit.

One important detail: you can only receive one extended child benefit payment, regardless of how many children you are raising alone. You still receive the standard child benefit for each individual child.

Example: If you are raising three children alone, you receive the standard child benefit for three children plus one extended child benefit payment per month.

Who qualifies for extended child benefit?

You may receive extended child benefit if you are raising children under 18 on your own and meet one of these conditions:

You are legally separated
You are divorced
You are unmarried and not living with the other parent
You are a surviving spouse (widow or widower)
You have been de facto separated for at least 6 months without a formal separation order
Your spouse or partner has been missing for at least 6 months
Your spouse or partner is imprisoned with an unconditional sentence of at least 6 months, or has been held in pre-trial detention for at least 6 months

In addition, these baseline requirements apply:

The child must reside in your country
You must have daily care of the child
You must not be living together with the other parent of the child

When unmarried cohabiting parents with children under 16 separate, many countries require mediation or family counseling before extended child benefit can be granted. Book your mediation appointment as early as possible — there may be a waiting period.

Extended child benefit and a new partner — when do you lose entitlement?

Many single parents wonder what happens to extended child benefit if they get a new partner. Here are the general rules:

You lose extended child benefit if:

You get married (regardless of who you marry)
You move in with someone you have children with — you lose entitlement immediately
You move in with someone you don't have children with, and you have lived together for at least 12 of the last 18 months

You keep extended child benefit if:

You have a partner who does not live with you
You are cohabiting with someone you don't have children with, and it has been less than 12 months

It is important to notify your benefits office if your living situation changes. Failing to do so may result in being required to repay any overpayment.

Benefits offices may check registered addresses. If you and a new partner register the same address, they will likely review whether you are still entitled to extended child benefit.

Parents discussing a shared custody agreement over documents

Extended child benefit with shared custody

A common question after a separation is how extended child benefit works with shared custody arrangements. It's important to understand the difference between shared residence and visitation.

What is shared residence?

Shared residence means the child lives permanently with both parents. This requires a written agreement between the parents, or a court order. It is not the same as regular visitation — even if the child spends a lot of time with the other parent, it is not shared residence unless there is a formal agreement.

Can you receive extended child benefit with shared custody?

Yes. If you are a single parent with a written shared residence agreement, you can apply for split extended child benefit — receiving half of the full extended benefit.

The child benefit is always split equally (50/50), regardless of how much time the child actually spends with each parent.

Requirements for a shared residence agreement

A shared residence agreement must include:

Names of the children the agreement covers
Date the agreement takes effect
A clear statement that it is a shared residence arrangement
Signatures from both parents

You can write the agreement yourselves, but both parents must sign it.

Tips for families with multiple children

If you have multiple children, you can choose to:

Split the child benefit for all children equally
Arrange it so one parent receives benefit for one child and the other receives it for another child

The second option may be more financially advantageous if both parents are single, as both can then receive their full extended child benefit for "their" respective children.

Example: If you have two children and both parents are single, you can agree that one parent receives full child benefit for child 1 and the other for child 2. Both then receive the full extended child benefit instead of the split amount. Check with your social services office about what works best for your situation.

How to apply for extended child benefit

The application process step by step

Contact your local social services or benefits office and log in to any online portal available in your country
Apply for child benefit — the application typically covers both standard and extended child benefit
Fill in your details about yourself, your child, and your living situation
Upload documentation (see below)
Submit your application — you will receive digital or written confirmation

Documentation you may need

Depending on your situation, you may need:

Separation order or divorce decree — if you are separated or divorced
Mediation certificate — if required when cohabiting parents with young children separate
Written shared residence agreement — if the child has shared residence
Court order — if a court has determined shared residence
Proof of residence or immigration status — if you or the child are foreign nationals

When does payment start?

You can generally receive extended child benefit from the month after you become a single parent
If you were married: from the month after your legal separation
If you were cohabiting with shared children: from the month after completing any required mediation
Payments continue until the month before the child turns 18

From standard to extended child benefit — transitioning after separation

If you are going through a separation, it's important to act quickly to start receiving extended child benefit as soon as possible:

The timeline to follow

Immediately: Book mediation or counseling if required for separated parents with young children
After mediation: Obtain your mediation certificate or completion document
As soon as documentation is ready: Apply for extended child benefit
Also consider: Transition support payments, advance maintenance, and other benefits for single parents

In many countries, child benefit can be backdated for a limited period if you were eligible but did not apply in time. However, it is always best to apply as quickly as possible to avoid delays.

Other benefits you should know about

As a single parent, you may be entitled to more than just extended child benefit:

Transition support payments — income support while you study or look for work
Childcare subsidies — covering part of daycare or after-school care costs
Child maintenance advance — if the other parent does not pay maintenance
Small children supplement — if you have children aged 0–3 and receive full transition support

Frequently asked questions about extended child benefit

Can I receive extended child benefit if I live with my own parents?

Yes, you can receive extended child benefit even if you live in your parents' home — as long as you are not living together with the other parent of your child. What matters is that you are genuinely a single parent.

Can both parents receive extended child benefit with shared custody?

Yes, if both parents are living alone (not in a new cohabiting relationship) and the child has shared residence, both can apply for split extended child benefit. Each parent then receives half the standard extended benefit amount.

What happens if I get a new partner?

If you get a new partner who you have children with, you lose extended child benefit immediately. If your new partner has no children with you, you keep entitlement for up to 12 months. After 12 of the last 18 months as cohabitants, the benefit ends. You are required to notify your benefits office of the change.

Do I pay tax on extended child benefit?

In most countries, child benefit payments — both standard and extended — are tax-free. Check with your local tax authority for the rules that apply in your country.

Can I receive extended child benefit straight away when I move out from my partner?

The timing depends on your situation. If you were married, you typically need a formal separation before becoming eligible. If you were cohabiting with shared children, you may need to complete mediation first. If you were cohabiting without shared children, you can usually apply as soon as you move apart.
