Partner moving into your Dutch rental: the rules

You have a room or apartment in the Netherlands, your relationship gets more serious, and at some point your partner wants to move in. Logical. But the Dutch rental market has its own rules here, and they differ depending on the type of housing and what your contract says. This article covers when you need permission, what happens if you skip the notification step, and how to do it properly.

Can your partner just move in?

It depends on two things: the type of rental and what your contract says.

Self-contained housing (own apartment or studio): in principle you can let someone live with you as long as you remain the main tenant and there is no conflicting clause in your contract. The landlord does not need to grant permission unless the contract explicitly requires it.

Non-self-contained housing (room in a shared house): more complex here. You rent your own room and the shared spaces are communal. If your partner also uses those shared spaces, the other housemates are affected. Always discuss with both your landlord and your housemates first.

Social housing (woningcorporatie): housing corporations set rules on who lives in the unit. You usually have to notify them that a partner is moving in. If you skip this and it comes out later, the corporation can take action including ending the contract.

What do Dutch rental contracts typically say about cohabitation?

Many contracts have a clause saying the home may only be inhabited by the tenant(s) named in the contract. In that case you must ask the landlord for permission before your partner moves in.

Some contracts explicitly allow cohabitation by a partner (or "a person with whom the tenant has a sustainable relationship"). In that case you only need to notify the landlord, not ask permission.

Read your contract carefully. If it is unclear, ask your landlord in writing what the rules are. Check our piece on the Dutch rental contract checklist before signing for what to look for.

What rights does your partner get after moving in?

This is the important part. If your partner moves in but does not become a co-tenant (medehuurder), they have very limited rights when the contract ends:

On your death your partner has no automatic right to continue the tenancy
If you terminate the contract, your partner must also leave
In a dispute with the landlord your partner has weak legal standing

To give your partner full rights, they can be added to the rental contract as co-tenant (medehuurder). This requires landlord consent but gives your partner full tenancy rights.

The route to medehuurderschap usually requires showing two things to the landlord:

You and your partner have a sustainable joint household (kept in the same address for at least two years, often longer)
Your partner is financially able to pay rent if you leave

If the landlord refuses without good reason, the subdistrict court (kantonrechter) can rule on it. The procedure is straightforward and you can prepare it with help from the Juridisch Loket.

What are the consequences for rent and service charges?

An extra resident can affect:

Service charges (servicekosten): more residents means higher energy use, so service costs based on actual use will rise. If service costs are fixed (forfait), they should not change.
Rent itself: the rent does not change because of a partner moving in. The landlord cannot raise it just because someone joins. The rent is tied to the home, not to headcount.
Rent allowance (huurtoeslag): this is the big one. If you receive huurtoeslag, your partner's income gets counted as joint income (toetsinkomen). This can reduce or eliminate your allowance. Always notify the Belastingdienst.
Energy contract: notify your energy supplier if it is on your name. You may want to switch to a higher contracted capacity.

How to register the cohabitation correctly

Step 1: Read your rental contract carefully. Does it require permission or only notification?

Step 2: Write a letter or email to your landlord stating that your partner is moving in (name, date of move-in).

Step 3: Request permission if the contract requires it. Keep the response in writing.

Step 4: Update your details with the Belastingdienst (Tax Office) if you receive rent allowance, healthcare allowance, or child-care allowance.

Step 5: Register your partner at the address with the municipality (BRP registration). See our BRP guide for internationals.

Step 6: Consider whether to add your partner to the contract as co-tenant for full legal protection.

International couples: extra layers

For non-Dutch couples moving in together in Amsterdam, there are a few extra things to think about beyond the standard process.

Residence permit (verblijfsvergunning) on basis of partnership: a partner without a Dutch passport may be applying for residence based on the relationship with the main tenant. The IND will ask for proof you live together at the same address. BRP registration is the standard proof, alongside a registered partnership or marriage if applicable.

Income test for huurtoeslag and other allowances: an international partner's income from abroad still counts for Dutch allowance calculations. Bring tax certificates from the home country if needed.

Cultural difference in "moving in": in the Netherlands cohabitation has legal weight even without marriage. The "samenleefovereenkomst" (cohabitation agreement) is worth setting up at a notary if you have significant assets or expect to share long-term finances.

What if you split up?

This is the hard scenario nobody wants to plan for, but worth knowing.

If only you are the contracted tenant, the home stays yours and your partner has to leave
If both of you are on the contract, you have equal rights to the home. One of you needs to leave, or you negotiate with the landlord about removing one name
Without clear agreements beforehand, this can escalate

A short written agreement at the start (a couple of paragraphs covering "if we split, who stays, who pays what for X months") prevents a lot of conflict. Read more about the legal context in our piece on hospita refusing notice.

Frequently asked questions

Do I have to register my partner at the address?

Yes. BRP registration is a legal requirement for anyone staying at an address in the Netherlands for four months or longer. Without registration your partner cannot access healthcare allowance, employment rights, or open Dutch bank accounts.

Can the landlord charge extra rent if my partner moves in?

No, not just because of an extra resident. The rent is tied to the unit, not headcount. The only exception is a specific contract clause that explicitly allows this, which is rare and often legally contestable.

What if my landlord refuses to let my partner move in?

If the contract has no clause prohibiting cohabitation, the landlord has limited grounds to refuse. Consult the Juridisch Loket if the landlord persistently refuses. For social housing, you can often appeal to a tenant ombudsman or the housing corporation's complaint line.

What if we split up, who keeps the room?

If only you are the contract holder, the room is yours. If both names are on the contract, you both have rights and must either negotiate or have one name removed. This can be complex, so written agreements at the start prevent much of the conflict.

Does my partner have the right to continue the tenancy if I die?

Yes, if your partner is registered at the address and you have a sustainable joint household, they often have the right to continue the tenancy. This applies to unmarried cohabiting couples as well as married ones. The process is called "voortzetting van de huur" and requires application to the landlord within six months.

Does my partner need to apply for co-tenancy (medehuurderschap)?

Not immediately, but it is worth doing if you plan to live together long-term. The application is usually made after at least two years of cohabitation. Co-tenancy gives your partner equal rights in case of dispute, separation, or your death.
