When you buy a house together in the Netherlands, the notarial deed fixes who owns which share, but you are each liable to the bank for the full mortgage, whatever you agree between yourselves. The main exception to equal treatment is what you put on paper: unequal contributions, parental gifts and what happens on separation or death are only protected if they are recorded before completion.
Unmarried partners inherit nothing from each other without a will, and living together for years creates no property rights. This article covers co-ownership, your relationship framework, unequal contributions, the mortgage, death and separation, in the order in which the decisions arise.
What does co-ownership mean under Dutch law?
Two or more people who buy a house together hold it in a community (gemeenschap) under Book 3 of the Dutch Civil Code (BW). Each holds an undivided share as stated in the deed of transfer; ownership passes when the notarial deed is registered in the public registers of the Land Registry (Kadaster).
Each co-owner may demand division at any time under Article 3:178 BW. You can agree to exclude that right, but only for a limited period, at most five years at a time. If you cannot agree on division, the court decides under Article 3:185 BW, for example by allocating the house to one of you against payment or ordering a sale.
Ordinary maintenance can be done by either co-owner, but selling or mortgaging the house requires all co-owners. This applies equally to partners, friends, siblings or a parent and child buying together.
Does it matter whether you are married or cohabiting?
Yes. For marriages and registered partnerships entered into since 1 January 2018, the default is a limited community of property: assets you had before, and gifts and inheritances, stay personal, while a house bought together during the marriage falls into the community. See our article on the oke obodo nke ihe onwunwe; nkwekọrịta tupu alụmdi na nwunye nwere ike igbanwe ya.
Under Article 1:88 BW a spouse needs the other spouse’s consent to sell or mortgage the family home, even if only one of them is the registered owner. Without consent, the other spouse can annul the transaction.
Unmarried couples need a notarial cohabitation agreement (samenlevingscontract) to arrange comparable matters. It can record the shares, allocate costs, regulate separation and include an accrual clause (verblijvingsbeding) under which the survivor takes over the deceased partner’s share in the house. It cannot create inheritance rights in other assets or a right to partner maintenance; see our comparison of a nkwekọrịta ibi n'otu ebe na alụmdi na nwunye.
How do you protect unequal contributions?
If one of you contributes more and the deed says fifty-fifty with nothing else in writing, half of the extra contribution is in principle lost to the other. Three documents prevent this, and they must say the same thing.
- The deed of transfer: the shares do not have to be equal. Unequal shares also divide future increases and decreases in value in that proportion.
- An internal liability agreement (draagplichtovereenkomst): it records who bears which part of the mortgage and costs between you, and what is repaid to whom before the remaining equity is divided. The bank is not bound by it.
- Documentation of family money: a parental contribution is a gift or a loan. A loan needs written terms on amount, interest, repayment and priority on sale. A gift can include an exclusion clause (uitsluitingsclausule) that keeps it outside any community of property.
The tax treatment of gifts and loans is a matter for a tax adviser; we deal with the civil-law documents and coordinate with your adviser.
What does joint liability for the mortgage mean?
If you both sign the mortgage deed, the bank can claim the whole debt from either of you. If you pay more than your internal share, you have a right of recourse against your partner, but that right is only worth what your partner can pay.
Moving out, a divorce settlement or an agreement between you does not end your liability to the bank. Only the bank can release a borrower, usually after assessing whether the remaining owner can carry the loan alone. Until then, the debt stays registered in your name at the Dutch credit registration office (BKR).
An exit clause therefore needs a valuation method and a deadline. It should state how the value is fixed, how long one partner has to obtain the bank’s consent and buy the other out, who pays the mortgage and costs meanwhile, and that the house will be sold if the deadline passes.
What happens if one of you dies?
A spouse or registered partner inherits under the statutory division; a cohabiting partner inherits nothing without a will. Without arrangements, the deceased partner’s share passes to blood relatives, and you may co-own your home with your late partner’s parents or children.
An accrual clause in the cohabitation agreement and a will solve this. Where there are children, their compulsory portion (legitieme portie) must be taken into account; see our article on Iwu ihe nketa nke ndị Dutch. The survivor also remains liable for the whole mortgage, so check whether life cover matches the debt and whether the beneficiary designation is up to date.
What should you check about the house and the purchase?
Co-ownership documents do not cure a bad purchase. Under Article 7:17 BW the house must have the properties you were entitled to expect, and you must notify the seller of a defect within a reasonable time after discovering it (Article 7:23 BW); see our guide on ịzụta ụlọ nwere ntụpọ zoro ezo.
As private buyers you have a three-day cooling-off period after receiving the signed purchase agreement (Article 7:2 BW). After that, your protection lies in the conditions for financing, a structural survey and, where relevant, the National Mortgage Guarantee (NHG). Each condition has a deadline and must be invoked in writing; see ịpụ na ihe onwunwe nke ndị Dutch zụtara.
The model purchase agreement requires a deposit or bank guarantee, customarily 10% of the price. Record who funds it, because it is itself a contribution. For an apartment, ask for the minutes, accounts, reserve fund and maintenance plan of the owners’ association (VvE); see VvE rights and obligations. With a ground lease, read the erfpacht conditions first.
The onye na-ede akwụkwọ iwu obodo executes the deed of transfer and the mortgage deed and checks the registers. The notary is impartial and does not advise either of you on how to divide ownership; that is why the co-ownership documents need separate attention.
How is the house divided when you separate?
There are three ways out: one of you takes over the house, it is sold, or the court decides under Article 3:185 BW. A takeover requires a new notarial deed and the bank’s release of the departing partner. A sale means dividing the net proceeds after redeeming the mortgage and settling documented contributions in the agreed order.
Agree in advance how the value is fixed, for example by an independent appraiser or the average of two valuations, and how long a valuation remains valid. If you cannot agree at all, the court may allocate the house or order a sale, which is usually worse financially than a negotiated result.
For spouses, the house is part of the wider settlement on divorce. For cohabitants, the cohabitation agreement sets the rules; see nkewa site na nkwekọrịta ibi n'otu ebe. Until division is complete you both remain owners and liable, so record in writing who lives in the house and who pays what from the day one of you moves out.
What should each co-buyer check?
Each of you has your own interests, even if you buy as a couple. Check these points before the notary appointment.
- Do the shares in the draft deed match what each of you contributes, or is there a liability agreement that corrects them?
- Is every parental contribution documented as a gift, with or without an exclusion clause, or as a loan with written terms?
- If you are not married, is there a notarial cohabitation agreement with an accrual clause, and does each of you have a will?
- Does the exit clause contain a valuation method, a buyout deadline and a fallback sale?
- Is life cover aligned with the mortgage and are the beneficiaries correct?
What should the partner who leaves check?
If you move out, your liability does not end with your departure. Check these points.
- Has the bank released you in writing from the mortgage?
- Has your share been transferred by notarial deed, and has the price been paid?
- Have your documented contributions been repaid in the agreed order?
- Is it recorded who pays the mortgage, insurance and VvE contributions until the transfer?

- Unequal contributions and family money are only protected if documented before completion.
- Unmarried partners inherit nothing from each other without a will and an accrual clause.

Ọtụtụ mgbe Ẹbụp Ajụjụ
Do we need a cohabitation agreement if we buy together?
It is strongly advisable. Without one, unmarried partners have no arrangement for separation and no accrual of the share in the house on death. A notarial cohabitation agreement with an accrual clause (verblijvingsbeding), combined with wills, fills that gap.
Can our shares in the house be unequal?
Yes. The deed of transfer can record any division, such as 70/30. Alternatively, you own in equal shares and use an internal liability agreement to settle unequal contributions before the equity is divided.
Am I still liable for the mortgage after I move out?
Yes. Both borrowers are liable for the whole debt until the bank releases one of them in writing. An agreement between you or a divorce settlement does not bind the bank.
Can my co-owner refuse to sell?
Each co-owner may demand division at any time (Article 3:178 BW). If you cannot agree, the court decides how the house is divided under Article 3:185 BW, for example by allocation to one of you or by sale.
Does my spouse need to consent to selling our home?
Yes. Under Article 1:88 BW a spouse or registered partner needs the other’s consent to sell or mortgage the family home, even if only one of them is the registered owner.
