Buying a house together in the Netherlands means three separate legal questions have to be answered at once: who owns which share, who owes the mortgage, and what happens if one of you leaves or dies. The ownership share is fixed in the notarial deed of transfer and registered at the Kadaster. Liability to the bank is joint and several regardless of what you agreed between yourselves. And unmarried partners inherit nothing from each other without a will. Each of the three is settled by a different document, and getting them to say the same thing is the whole exercise.
Most disputes between co-owners are not about the property. They are about a deposit that one of them paid and the other cannot repay, a parental gift that was never documented, or a mortgage that the departing partner is still liable for two years after moving out. All three are avoidable with paperwork prepared before completion. This article sets out what Dutch law actually provides, in the order in which the decisions arise.
What co-ownership means under Dutch law
When two or more people acquire a property together, they hold it in a simple community (eenvoudige gemeenschap) under Book 3 of the Burgerlijk Wetboek (Civil Code). Each co-owner holds an undivided share; nobody owns a particular room. The shares are what the deed of transfer says they are, and they are presumed equal only if the deed is silent. Ownership passes on execution of the notarial deed and its registration in the public registers, not on signature of the purchase agreement.
Two consequences follow from that structure. The first is that a co-owner cannot be forced to remain in the community: each of you may demand division at any time, and if you cannot agree the court will decide how the property is divided, which in practice usually means a sale or an allocation to one of you against payment. A co-ownership agreement can suspend that right for a fixed period, but not indefinitely.
The second is that decisions about the property require agreement. Ordinary maintenance can be carried out by either of you, but selling, mortgaging or substantially altering the property requires the consent of all co-owners. A partner who refuses to cooperate with a sale can be compelled through the court, but that takes months, which is why an agreed exit mechanism is worth more than any argument about who is being unreasonable.
None of this depends on the state of your relationship. Co-ownership between friends, siblings or a parent and child works in exactly the same way as between partners, and the documents described below are just as necessary.
Marriage, registered partnership or a cohabitation agreement
Your relationship framework decides what happens to the property automatically, and how much has to be arranged by hand. There is no such thing as an informal partnership that acquires rights over time in Dutch law: living together for ten years creates no property rights and no inheritance rights whatsoever.
For marriages and registered partnerships entered into from 1 January 2018, the default regime is the limited community of property. Assets and debts each of you already had remain personal, as do gifts and inheritances received during the relationship; what you build up together becomes common. A house bought during the marriage in both names therefore falls into the community, but a house one of you owned beforehand does not, and neither does the debt attached to it. Our article on the limited community of property explains how the boundary is drawn, and prenuptial agreements can move it.
Unmarried couples need a notarial cohabitation agreement (samenlevingscontract) to achieve anything comparable. It can record the ownership shares, allocate the running costs, deal with what happens on separation, and contain a verblijvingsbeding under which the survivor takes the deceased partner’s share in the property. What it cannot do is create inheritance rights in anything else, or a right to partner maintenance, or an entitlement to a share in the other’s pension. The differences are set out in our comparison of a cohabitation agreement and marriage.
One point catches married couples out. Where the property is the family home, the Civil Code requires the consent of the other spouse for a range of transactions concerning it, including granting a mortgage over it and, in most cases, selling it. That protection applies even where only one spouse is the registered owner.
Unequal contributions: the deed, the gift and the draagplichtovereenkomst
The most common source of conflict is money that went in unequally and came out equally. If one of you contributes savings or receives a parental gift and the deed records a fifty-fifty split with no further agreement, half of that contribution has, in law, been given away. Three instruments prevent this, and they have to be consistent with one another.
The first is the deed itself. Ownership shares do not have to be equal, and setting them to reflect the contributions is the cleanest solution where the difference is permanent and substantial. It is not always the best solution, because the shares then also govern future value growth, which may not be what you intend.
The second is a draagplichtovereenkomst, an agreement on internal liability. It records who, as between the two of you, bears which part of the mortgage debt and the running costs, and what is to be repaid to whom before the remaining equity is divided. This is the instrument that lets you own the property in equal shares while still ensuring that a deposit of one hundred thousand euros comes back to the person who paid it. It has no effect on the bank, which is precisely the point: it settles the internal position, and the bank keeps its own rights.
The third concerns family money. A parental contribution is either a gift or a loan, and the difference has to be documented at the time, not reconstructed afterwards. A loan needs written terms: amount, interest, repayment, and its ranking on a sale. A gift can be made subject to an exclusion clause (uitsluitingsclausule), which keeps it outside any community of property and outside the reach of a division on divorce. Without such a clause, a gift made to one partner during a marriage in community can end up shared. Whether a particular structure is advantageous for gift tax is a question for a tax adviser; we deal with the civil-law side and coordinate with yours.
Whatever you choose, keep the documents aligned. A deed that says fifty-fifty, a liability agreement that says seventy-thirty and a loan agreement that says nothing about priority on sale is a dispute waiting to happen.
The mortgage: joint liability and what it survives
Where both of you sign the mortgage deed, you are each liable for the whole debt, not for half of it. The lender can pursue either of you for the full amount and is not concerned with what you agreed between yourselves. The co-borrower who pays more than their internal share has a right of recourse against the other, but that right is only worth what the other can actually pay.
The practical consequence people underestimate is what happens on separation. Moving out does not end liability, and neither does a divorce settlement, a court order or a signed agreement between the two of you. Only the lender can release a borrower, and it will normally do so only if the remaining owner can carry the loan alone, which usually means a fresh affordability assessment and often a new mortgage. Until that release is granted, the departing partner remains liable and the debt continues to appear in the national credit register, which limits their capacity to buy elsewhere.
That is why an exit clause has to be dated. A workable clause fixes how the property is valued, gives one partner a defined period in which to obtain lender consent and complete a buyout, sets out who lives there and who pays the mortgage, the owners’ association contributions and the insurance in the meantime, and provides that the property goes on the market if the deadline passes. Without a long-stop date, a partner who cannot refinance but will not sell can hold the other hostage indefinitely.
Mortgage products, interest deduction and the national mortgage guarantee are matters for a mortgage adviser rather than a lawyer, and the tax treatment of interest, of an earlier sale and of any earlier home ownership belongs with a tax adviser. Our role is to make sure the deed, the liability agreement and the exit clause say what you think they say.
What happens if one of you dies
This is where unmarried couples are most exposed. Under Dutch inheritance law a spouse or registered partner inherits under the statutory division; a cohabiting partner inherits nothing at all unless there is a will. If your partner dies without one, their share in the house passes to their blood relatives, and you may find yourself co-owning your home with your late partner’s parents or siblings.
Two documents solve this. A verblijvingsbeding in the cohabitation agreement provides that the deceased partner’s share in jointly held assets, including the house, passes to the survivor, usually against an obligation to take over the corresponding debt. And a will deals with everything the cohabitation agreement cannot reach. Where there are children from an earlier relationship, the legitimate portion (legitieme portie) has to be taken into account; our article on Dutch inheritance law explains how the statutory division and the legitimate portion work.
Separately from the question of who inherits, there is the question of who can pay. The survivor remains liable for the full mortgage, and one income has to carry a loan that was assessed on two. Term life cover sized to the outstanding debt, with the beneficiary designation aligned to the rest of the arrangements, is the standard answer. Check the designation whenever the relationship or the ownership changes; an out-of-date beneficiary clause is a common and expensive oversight.
Inheritance tax treatment of a partner’s estate depends on formal criteria that differ for spouses, registered partners and cohabitants, and on the content of any cohabitation agreement. That is a matter for a tax adviser or a civil-law notary; what matters legally is that the civil arrangements exist at all.
Checking the property itself
Co-ownership documents do not cure a bad purchase. Under Dutch law the property must correspond to what the buyer was entitled to expect given the agreement, and the seller has a duty to disclose defects known to them that affect normal use. The buyer, in turn, has a duty to investigate. Standard purchase agreements shift much of the risk to the buyer through an age clause or a clause stating that the seller has never lived in the property, and those clauses are generally effective.
Timing is critical if something does go wrong. The two-month complaint period that consumers know from the purchase of goods does not apply to the purchase of a house: for immovable property the buyer must complain within a reasonable time (bekwame tijd) of discovering the defect, which in practice means promptly, in writing, and with an opportunity for the seller to inspect. Waiting until the repair has been carried out and the invoice paid is a good way to lose an otherwise sound claim. Our article on the hidden defects time limit sets out how the courts apply it, and our guide on buying a home with hidden defects covers the substantive claim.
For an apartment, you are also buying into an owners’ association. Ask for the minutes of the last three general meetings, the annual accounts, the level of the reserve fund, the long-term maintenance plan and any arrears, and find out whether major works have been resolved on but not yet invoiced. A decision taken before you bought can still land on your doormat afterwards. Our article on VvE rights and obligations explains what the association can and cannot require of you.
Where the land is held under a ground lease, read the leasehold conditions before you commit. The ground rent, the mechanism and moment of its revision, the permitted use and any buy-out option can affect both the monthly cost and the saleability of the property, and lenders take a view on unfavourable conditions. See our explanation of erfpacht for buyers, and consider taking advice from a real estate lawyer before signing.
The purchase process and the deadlines that matter
The Dutch purchase runs from an accepted offer to a written purchase agreement, then to the notarial deed of transfer. For a buyer who is a private individual buying a home, the agreement must be in writing to be binding, and the buyer has a statutory cooling-off period of three days from receipt of the signed agreement in which to withdraw without giving reasons and without cost. The period cannot be contracted away, and it is calculated in calendar days with a rule that ensures at least two of them are working days.
Beyond that, your protection comes from the conditions you negotiate into the agreement. The three that matter most are a financing condition, a condition covering the outcome of a structural survey, and, where relevant, one covering the national mortgage guarantee. Each needs a scope, a deadline and a statement of what evidence must be produced to invoke it. These conditions lapse automatically on their date: a buyer who fails to invoke a financing condition in time is bound to the purchase and, under the standard model agreement, exposed to a penalty. Where a purchase has gone wrong, our article on withdrawing from a Dutch property purchase sets out what is still possible.
The model agreement also requires the buyer to provide a deposit or a bank guarantee, customarily ten per cent of the purchase price, within a set period. Both co-buyers should know who is funding it and out of which account, because that payment is itself a contribution that ought to be recorded.
Completion takes place at the civil-law notary, who prepares and executes the deed of transfer and the mortgage deed, checks the public registers for existing charges and attachments, settles the purchase price through the notarial client account and registers the deeds. The notary is impartial and acts for both parties, which means the notary is not your adviser on whether the deal is a good one or on how to allocate ownership between you. Our guide to the Dutch notary and the legal transfer of a property explains the division of roles, and our article on transfer tax and buyer’s costs covers what has to be paid around completion.
Expect identity checks and questions about the source of your funds from both the lender and the notary; these are statutory obligations, not suspicion. Answering them with documents you have gathered in advance is the difference between a smooth completion and a delayed one.
Separating: how the property is actually divided
On a separation the house has to leave the community, and there are only three ways out: one of you takes it over, it is sold to a third party, or the court decides. Taking it over means being allocated the whole property against payment of the other’s share, which requires the lender to release the departing owner and a fresh notarial deed. Selling means dividing the net proceeds after the mortgage is redeemed, and after any documented deposits, gifts and loans have been settled in the order your agreement provides.
The valuation is where negotiations stall. Agree in advance how the value is to be fixed: a valuation by an independent appraiser, or the average of two appraisals with a third if they differ by more than an agreed margin, together with a validity period so that a slow negotiation does not overtake the figure. If you leave this open, you will be arguing about the appraiser rather than about the house.
Where the parties cannot agree at all, either co-owner can ask the court to order the division. The court has broad discretion: it can allocate the property to one party against payment, order a sale, or order a sale by auction if cooperation is refused. That last outcome is almost always worse financially than any negotiated result, which is the strongest practical argument for settling. For married couples the property forms part of the wider financial settlement on divorce and cannot sensibly be dealt with in isolation; for cohabitants the position is set by the cohabitation agreement, and our article on separating with a cohabitation agreement works through the sequence.
Until the division is complete, both of you remain owners and both remain liable. Record who occupies the property, on what basis and at whose cost, and record it in writing at the moment one of you moves out rather than months later.
Mistakes that cost the most
Assuming that living together creates rights is the most expensive of them, because the discovery usually comes at the worst possible moment. Second is the equal deed with unequal money and nothing in writing; the contribution is simply gone. Third is leaving the mortgage in joint names after one partner has moved out, which keeps that partner liable and blocks their next purchase. Fourth is an exit clause with no valuation method and no deadline, which converts a solvable disagreement into a court case. Fifth is complaining too late about a defect.
All five are document problems, and all five are cheaper to prevent than to litigate. The natural moment is between the accepted offer and the notary appointment, when the terms are known and there is still time to draft.
