Purchase of real estate during marriage and community of property

Property acquired during marriage generally falls into joint marital property unless the spouses have agreed otherwise. A purchase agreement signed by only one spouse can create disputes and, in serious cases, threaten the validity of the transaction. The article explains how to verify the marital property regime and why involving both spouses is usually safer.

Key takeaways

  • Real estate acquired during a marriage automatically falls into the Community Property of Spouses. If you are married and have not modified your community property regime, any real estate purchased during the marriage automatically becomes part of your community property, along with any related liabilities, such as a loan.
  • The signing of a purchase agreement by only one spouse carries risks. The conclusion of a real estate purchase agreement by only one spouse without the consent of the other can lead to serious complications and unpleasant consequences for all parties involved.
  • The other spouse's dissent can nullify the entire purchase. If the other spouse does not consent to the real estate purchase and learns of it only subsequently, they may take legal action, which can result in the invalidity of the purchase agreement and the cancellation of the entire transaction.
  • The seller may claim damages. If the buyer concealed their marital status or falsely claimed to have the other spouse's consent, the seller may be entitled to claim damages in the event the purchase is cancelled.
  • The Cadastre verifies the buyer's marital status. When registering the transfer of ownership, the Cadastral Office may discover that the buyer is married and may require proof of the reason why the real estate should be registered in the name of only one of the spouses.

What is community property (SJM) anyway?

As a rule, real estate purchased during the marriage automatically becomes part of the spouses' community property (unless there are specific cases, which we will discuss more in the next article). At the same time, it is important to note that, in addition to the property, liabilities incurred during the marriage (e.g. a loan in connection with the purchase of the property which finances the purchase price or part of it) generally become part of the matrimonial property.

For the purposes of this article, we will assume a model situation where one of the spouses acts on the buyer's side, where the spouses have not regulated the SJM differently from the "basic" statutory regime, and this is a standard case where the property would automatically be included in the SJM.

What if only one spouse signs the purchase contract for the property?

Thesigning of a contract of sale for a property by only one spouse can bring significant risks and complications. Generally, this situation should not arise at all with careful preparation, as it should always be checked when preparing the contractual documentation whether the party to the contract on the buyer's side is married and whether the property will be acquired in the community property.

In practice, however, it may happen (especially if the contracting parties prepare the purchase contract themselves and are unaware of the potential risks involved) that the purchase contract is signed by only one spouse. Such a situation can have unpleasant consequences for all parties involved.

The worst scenario that can arise is when one spouse concludes a contract of sale for a property in this way without the other spouse's knowledge, or even concludes the contract despite knowing that the other spouse does not expressly agree to it.

In the event that the other spouse only becomes aware of the conclusion of the contract of sale afterwards and does not agree to the purchase, he or she has the possibility to defend himself or herself against this legal action of the other spouse. The consequence may then be (simply put) the nullity of the purchase contract and the "annulment" of the entire purchase of the property. Such a situation is then extremely unpleasant for both the buyer and the seller.

At the same time, it could also lead to a situation in which the seller could be entitled to compensation against the buyer (e.g. if the buyer, despite the seller's enquiry, conceals or denies that he/she is married and that the property is to be acquired in the jointly owned property, if he/she claims that the other spouse agrees to the purchase, etc.).

Furthermore, if the Land Registry, in the course of its activities, finds out that the buyer is married, it could be asked to provide a reason why the ownership of the property should be vested in only one of the spouses.

Caution - neither the signature of the purchase contract by only one spouse nor the registration in the Land Registry against one spouse (in general) means that the property does not belong to the community property!

It is important to remember that even if only one spouse signs the contract and even if the ownership of the property is registered in the land register against only one spouse, the property will still belong to the community property.

Thefact that only one spouse signs the contract, and the registration on the title deed will also be made against only one spouse, does not (generally) mean that only one spouse actually owns the property. This is often an unpleasant discovery for one of the spouses only in the event of a divorce and the related settlement of their community property.

Frequently asked questions about a purchase contract signed by only one spouse

1. Is a purchase contract signed by only one spouse automatically invalid?

No, it is a case of relative invalidity. If the other spouse did not agree to the purchase, he or she may invoke the invalidity of the contract (Section 714(2) of the Civil Code). Until he or she does so, the contract is valid, and if he or she never does, it remains valid.

2. What if the other spouse refuses to consent to the purchase without a serious reason?

In that case, the spouse who wishes to buy the property may ask the court to replace the consent. The court will do so if the refusal is contrary to the interests of the spouses, the family or the family household, or if the other spouse is unable to express his or her will.

3. Does a loan taken out for the purchase by only one spouse also form part of the community property?

As a rule, yes; debts incurred during the marriage form part of it. An exception is a debt incurred by only one spouse without the consent of the other where it did not concern the ordinary needs of the family (Section 710 of the Civil Code).

So how to avoid any inconvenience?

In order to avoid potential problems, it is essential that both spouses agree to the purchase of the property. Ideally, of course, this means that both spouses will sign the purchase contract and the property will also be registered in the Land Registry as belonging to the buyers' joint property.

If this is not possible for any reason, or if the purchase contract has already been signed by only one spouse, the spouse who has not signed the purchase contract must give his/her written consent to the conclusion of the purchase contract. This will avoid any problems in the future when the purchase contract may be contested by the other spouse.

What can you take away from the above?

  1. When preparing the contract documents, make sure to carefully prepare and verify whether or not the buyer is married and whether the property will be acquired in a jointly owned property.
  2. If the buyer is married, ensure that the purchase contract is signed by both spouses. If this is not possible, have them sign a written consent to the purchase agreement in advance.
  3. The conclusion of the purchase contract by only one spouse does not generally mean that the property will not belong to the community property.
  4. The fact that the ownership right is registered in the Land Register only in relation to one spouse does not automatically mean that the property is not part of the community property.

If you are planning to sell or buy a property, always ensure that the contractual documentation is carefully prepared. Incorrectly set up contracts can cause considerable complications and, in extreme cases, even invalidate the whole process of selling and buying the property.

If you are not sure how to proceed and what the contract should contain, consult experts - the cost of preparing the contract documentation is usually negligible compared to the potential costs in a situation where complications have to be dealt with afterwards.

Frequently asked questions about buying real estate during marriage

1. Does real estate purchased during the marriage always belong to the community property?

As a rule, yes. Exceptions include, for example, real estate that one spouse acquired by gift or inheritance, or that he or she purchased with funds from his or her separate property, such as from the sale of a flat he or she owned before the wedding (Section 709 of the Civil Code).

2. Does the registration in the Land Registry determine ownership?

No. Even if only one spouse is registered in the Land Registry, the property may belong to the community property. Who owns the property is determined by the statutory conditions of its acquisition, not by who signed the purchase contract.

3. How can a dispute over the purchase of real estate during marriage be avoided?

The safest option is for both spouses to sign the purchase contract. If this is not possible, the other spouse should give prior written consent to the purchase so that the contract cannot be challenged later. In practice, written consent can also be provided subsequently, ideally before the application for registration in the Land Registry is filed.

4. Can spouses buy real estate into the ownership of only one of them?

Yes, if they arrange this in advance by a marital property regime agreement, for example by narrowing the scope of the community property (Section 717 of the Civil Code). The agreement requires the form of a public deed, in practice a notarial deed. Without such an agreement, the property will as a rule become part of the community property even if only one spouse is buying it.
