Spousal maintenance (partneralimentatie) in the Netherlands ends by law when the recipient remarries, enters into a registered partnership, or starts living with someone else as if they were married (Article 1:160 of the Dutch Civil Code, BW). Child maintenance (kinderalimentatie) does not end: it is owed to the child, not to your former spouse, and a new partner does not change that.
Once Article 1:160 BW applies, the spousal maintenance is gone permanently and does not revive if the new relationship breaks down. In practice, the difficulty is proving cohabitation and knowing what you may do while you gather that proof.

When does spousal maintenance end because of a new partner?
Article 1:160 BW lists three events: remarriage, a registered partnership, or living together with another person as if married or registered. The obligation then ends on the date the situation arises, not just reduced or suspended.
The ending is automatic in law but not in practice. If your former spouse disputes it, you need a court decision establishing that the condition was met, and until then the existing order can still be enforced against you. Because the effect is permanent, Dutch courts interpret the provision restrictively: a serious new relationship alone is not enough.
विवाह आणि नोंदणीकृत भागीदारी
These two grounds are straightforward. Both are recorded in the Personal Records Database (Basisregistratie Personen, BRP), so the date is fixed, and maintenance ends on that date whether or not your former spouse still needs the money.
A religious marriage without civil effect in the Netherlands does not trigger Article 1:160 BW by itself. It can, however, be evidence of the durable relationship that matters for the third ground.
Living together as if married
This is the ground that ends up in court. Under the case law of the Supreme Court (Hoge Raad), four requirements must all be met at the same time:
- a durable affective relationship between the recipient and the new partner;
- cohabitation, meaning they share a home;
- a joint household, with shared costs and shared organisation of daily life;
- mutual care, so that each contributes to the other, not just one to the other.
Failing one requirement defeats the whole claim. Partners who stay over several nights a week but keep separate homes and finances do not meet the test. The law sets no minimum period, but the relationship must be durable rather than a trial, and the court looks at the situation over time.
Registration at the same address in the BRP is strong evidence but neither necessary nor sufficient. People who really live together while keeping separate registrations fall within Article 1:160 BW; housemates without a relationship do not.
How do you prove that your ex is cohabiting?
The burden of proof lies on the party who wants the maintenance to stop, usually the payer. The court assesses the evidence freely, but documents showing a shared economy carry far more weight than observations of a relationship.
A BRP extract showing both people at the same address is the best starting point. Stronger still are a tenancy agreement or mortgage deed in both names, joint bank accounts, a shared home or liability insurance, utility contracts in both names and post addressed to both at one address. Witness statements from neighbours and सामाजिक मीडिया posts support the picture but rarely carry a case alone.
Regular overnight stays, holidays together and appearing as a couple at family events only prove the affective relationship. They say nothing about a joint household or mutual care, and a file built only on that material tends to fail.
If you use a private investigation agency, the GDPR and the right to respect for private life under Article 8 ECHR apply. Civil courts usually still admit unlawfully obtained evidence after weighing the interests involved, but targeted observation over a defined period is defensible, while sustained monitoring of a household is not.
Can you stop paying straight away?
No. A maintenance order or an agreement laid down in a court decision or notarial deed is enforceable; if you stop paying on your own assessment, a bailiff can seize your wages and the National Maintenance Collection Agency (Landelijk Bureau Inning Onderhoudsbijdragen, LBIO) can add collection costs. Keep paying and apply to the court, if necessary with a request for a provisional suspension.
What happens to child maintenance when your ex has a new partner?
Child maintenance continues. Under Article 1:404 BW both parents must contribute to the costs of care and upbringing of their minor children according to their means, and the new partner’s income is not added to the parent’s income.
From age 18 until the child turns 21, parents must contribute to living and study costs under Article 1:395a BW. A new partner becomes financially responsible for the child in only two situations, and both require a formal step.

Under Article 1:395 BW a step-parent must pay maintenance for the minor children of their spouse or registered partner who belong to their household, but only during that marriage or partnership. Unmarried cohabitation, however settled, does not create this obligation.
Where it arises, the step-parent pays alongside both parents. Under Article 1:397(2) BW each person who owes maintenance pays a share based on their means and their relationship to the child. That can reduce what the non-resident parent pays, but only after a court order.
When the new partner obtains joint parental authority
Under Article 1:253w BW a non-parent who exercises joint parental authority (gezamenlijk gezag) with a parent must pay maintenance for the child. This also applies to unmarried couples, and after the joint authority ends the obligation continues for as long as the authority lasted, but not beyond the child’s 21st birthday.
Joint authority is granted by the court on application, so it is a documented change of circumstances and a good reason to ask for a recalculation. Our नेदरलँड्समध्ये बालसंगोपन भत्त्याची गणना कशी केली जाते याचे स्पष्टीकरण sets out the elements the court uses.
How does a new partner affect the maintenance calculation?
Maintenance is based on the recipient’s need (behoefte) and the payer’s capacity to pay (draagkracht), as Article 1:397(1) BW requires. Courts follow the annual guidelines of the Expertgroep Alimentatienormen (the Tremanormen); they are not law, but are applied closely and change every year.
The guidelines limit the effect of a new household. Housing costs, for example, are calculated as a standard amount based on net income rather than the actual rent or mortgage. Moving in with a new partner and halving your rent therefore does not automatically lower what you receive or raise what you pay.
For child maintenance, a new partner with their own income is assumed to provide for themselves, so the payer’s capacity is assessed as for a single person. A new partner without income does not normally increase the payer’s deductible costs, although the court can depart from the guidelines if the outcome is unreasonable.
For spousal maintenance, either Article 1:160 BW applies and the obligation ends without any calculation, or it does not apply and the new partner’s income is not counted. A real change in the recipient’s own income or costs can still justify a new calculation.
All maintenance amounts are indexed by law every year on 1 January under Article 1:402a BW, at a percentage set by the Minister of Justice and Security and published in the Government Gazette (Staatscourant). Forgetting the indexation is one of the most common causes of arrears.
How do you change or end maintenance?
Apart from the annual indexation and Article 1:160 BW, nothing changes by itself. You need a new agreement with your former spouse or a court decision.
करारानुसार
You can agree a new amount, or agree that maintenance has ended, in an amended divorce settlement agreement (echtscheidingsconvenant), for example through mediation. A private agreement is only directly enforceable if it is laid down in a notarial deed or a court decision. Under Article 1:400(2) BW any agreement waiving maintenance owed by law is void, which protects the child’s entitlement in particular.

The LBIO collects maintenance if the payer defaults and handles international recovery. It does not set, recalculate or vary the amount; only the parties or the court can do that.
न्यायालयामार्फत
Under Article 1:401(1) BW the court can change or withdraw a maintenance order or agreement if it no longer meets the statutory standards because circumstances have changed. Under Article 1:401(4) BW a court decision can also be changed if it was based on incorrect or incomplete information from the start. A request to establish that maintenance has ended under Article 1:160 BW follows the same route.
The request is filed with the district court by a lawyer (advocaat); representation is mandatory. The other party can file a defence, and the court holds a hearing before it decides. Where cohabitation under Article 1:160 BW is established, the court can set the end date at the start of the cohabitation rather than the date of the request.
What if your agreement has a non-modification clause?
Article 1:159 BW allows spouses to agree in writing that spousal maintenance cannot be changed by the court because of changed circumstances (niet-wijzigingsbeding). Under Article 1:159(3) BW the court can only set the clause aside if circumstances have changed so drastically that holding you to it would be unreasonable, a high threshold.
Such a clause does not stop Article 1:160 BW, because that provision ends the obligation by law rather than by variation. Under Article 1:159(2) BW the clause also lapses if the agreement was made before the divorce request and the request was not filed within three months. A related question, whether payment stops at state pension age, is answered in our article on AOW वयात जोडीदाराला मिळणारी पोटगी आपोआप संपते की नाही.
Can maintenance paid during cohabitation be reclaimed?
In principle, yes. Once a court establishes that Article 1:160 BW applied from a certain date, maintenance paid after that date was paid without legal ground and can be reclaimed as an undue payment under Article 6:203 BW.
Courts are cautious where the money has been spent on ordinary living costs and repayment would cause hardship, and they can limit the amount or period. A recipient who actively misled the payer has a weak case for that caution. Many settlement agreements also contain a duty to report a new living arrangement; breaching it is a breach of contract.
What should you check as the paying ex-spouse?
The burden of proof under Article 1:160 BW is on you, so build the file before you confront anyone.
- Request a BRP extract for the address where you believe your ex lives with the new partner.
- Collect evidence of a joint household and mutual care over several months, not only proof of the relationship.
- Keep paying, including the annual indexation under Article 1:402a BW, until the court has ruled.
- Check your settlement agreement for a duty to notify, a non-modification clause, a definition of cohabitation or a trial period.
- Have any surveillance limited to a defined period and purpose, so the evidence remains usable.
- Do not wait: arrears you want to reclaim grow every month, and records get harder to obtain.
What should you check as the receiving ex-spouse?
Whether Article 1:160 BW applies to your new relationship is a legal question with a permanent answer, so check before you move in together.
- Assess your situation against the four requirements: durable relationship, shared home, joint household and mutual care.
- Read your settlement agreement for a duty to notify a new living arrangement.
- If you want a trial period, agree it in writing with your former spouse; the law does not provide one.
- Do not rely on keeping two registered addresses: the court looks at how you actually live.
- Keep records of your own income and costs in case the payer asks for a recalculation under Article 1:401 BW.

सतत विचारले जाणारे प्रश्न
Does my ex’s new partner’s income count in the maintenance calculation?
No. The new partner’s income is not added to your ex’s income. If the cohabitation meets the test of Article 1:160 BW, spousal maintenance ends entirely and no calculation is made.
Does spousal maintenance end if my ex marries or registers a partnership?
Yes, by law on the date of the marriage or registration (Article 1:160 BW). If your ex disputes this, you can ask the court to establish that the obligation has ended.
Does child maintenance stop when my ex has a new partner?
No. Child maintenance is owed to the child (Article 1:404 BW). A new partner only contributes as a married or registered step-parent (Article 1:395 BW) or when sharing parental authority (Article 1:253w BW).
Can I stop paying when I think my ex is cohabiting?
No. The order or agreement remains enforceable until the court rules. Keep paying and file a request with the district court through a lawyer; overpaid maintenance can in principle be reclaimed later.
Does a trial period apply when my ex moves in with someone?
Only if you agreed one in writing, usually in the divorce settlement agreement. The law itself does not provide a trial period.
