Do you suspect that your partner’s financial situation is unresolved, or do you not even have a very indicative overview of it? Is your spouse running a business and you are worried that you will be liable for any debts from the business with your own assets? How can you effectively protect yourself in such cases?

Quick summary

  • The community property includes not only assets but also some debts.
  • A debt owed by one spouse may not automatically burden the other, especially if it was an obligation outside the normal needs of the family.
  • A prenuptial agreement can narrow the community property or set up separate property regimes.
  • The agreement can be concluded after the marriage as a marriage contract, but it cannot retroactively wipe out debts already incurred.
  • If there is a risk of execution or one spouse’s business, it is worthwhile to have the contract registered in a public register with a notary.

Do you want to protect your property from your partner’s debts or business risk? We will prepare a tailor-made prenuptial agreement or marriage contract and ensure the correct procedure, including notarisation.

From our law practice:

Several years ago, Mr. Robert contacted the firm of Affordable Advocate with questions regarding the appropriate legal form and the establishment of a travel agency. He was accompanied by his fiancée Eva, who supported her partner in everything, including his new business plan. However, as the more cautious of the couple, she also wanted to make sure that her (or rather their joint) assets would be safe, even if times were not in favour of the development of the travel agency or the business plan did not work out.

Therefore, in view of the planned marriage, we also advised the fiancés to conclude a prenuptial agreement, suggested its content and mediated its conclusion at a notary public’s office as provided for by law. Some time ago, we also received feedback on this case. Unfortunately, the era of covid lockdowns and travel bans favoured more established and stable travel agencies, which was not the case with Mr Robert’s agency. Travel around the world was made impossible, customers cancelled tours en masse, and Mr Robert found himself first penniless and then in considerable debt. In retrospect, both spouses welcomed the tip that they had entered into a prenuptial agreement that protected their assets, including their shared home, from foreclosure.

What about debts during the marriage?

Community property includes not only assets but also debts. Therefore, if you and your wife take out a loan or mortgage together, this liability will also be community property. However, a joint debt will also arise if only one spouse makes a commitment, for example, to buy a new television on hire purchase. If it is a really big commitment, such as a loan for a new car, and the other spouse had no idea about it and then did not agree to it, then such a commitment will be the sole debt of the spouse who made it (and has to pay it back out of his/her own funds).

What does a prenuptial agreement entail?

A prenuptial agreement is a document that can be concluded by the spouses, or in the form of a marriage contract, who wish to regulate whether they will have joint property as spouses and what will belong to it, or whether they will each have completely separate property. However, it really only concerns property. If it is entered into by the spouses, then it begins at the time of the marriage. A pre-nuptial agreement can not only narrow the matrimonial property but also extend it and choose who may dispose of the property and how.

If one of the partners has debts, is running a business or is planning major financial commitments, a generic model agreement downloaded from the internet is not enough. A prenuptial or marriage contract needs to correctly set out the scope of the community property, how the assets are to be disposed of and practical protection from creditors. We will be happy to prepare a prenuptial agreement for you, explain the implications of the different options and ensure that the agreement meets the legal requirements.

Tip for article

We have discussed the general requirements and procedure for concluding a prenuptial agreement in our blog article.

Protection of debtors’ partners

It can happen to almost anyone if, for example, their business fails or they fall into debt due to other adverse circumstances. If a person who owes a large amount of money or is directly affected by a foreclosure wants to get married in that situation, the other spouse’s happy moments need not be clouded by the prospect of being in a similar situation themselves. The solution is a prenuptial agreement that protects the debtor’s partner’s assets.

Keeping careful records and hiding invoices and receipts is worthwhile for everyone. However, if you are entering into a marriage with a person who has debts or runs a risky business, really take this advice to heart. It may come in handy when you have to prove that you bought a particular item with your own money and that it does not belong to your indebted spouse or is not part of the community property. You can also prove the origin of cash in the household, for example by keeping a withdrawal slip from an account where you only have your own money.

In a situation where a prenuptial agreement is concluded primarily with regard to existing or potentially foreseeable debts, it may also be advisable to enter it in the List of Deeds on the matrimonial property regime. A notary public may register the agreement. The advantage is greater protection of the matrimonial property. In the event of an execution directed against one of the spouses, the executor must verify the existence of such a contract and be guided by its contents. Similarly, the validity of such a contract can always be invoked against third parties, even if they have not been made aware of its contents. The property of the other spouse is thus secured.

If you do not make the contract public, you should make third parties, and in particular the executor, aware of the contents of the contract and document the contract.

Tip for article

If you disagree with what the executor has included in the inventory, you can protect your property by filing a motion to exclude the item from the inventory. We discuss this topic in more detail in our article.

The relationship between the debts of one spouse and their payment by the other spouse has been dealt with by the Supreme Court in one of its judgments. It stated that “the purpose of marriage cannot be to pay the debts of the other spouse incurred before the marriage; the opposite would be extremely contrary to the principles of justice, since it would lead to an unacceptable strengthening of the creditor’s right at the expense of the debtor’s spouse.” Thus, if a creditor is recovering a debt which arose before the debtor’s marriage and has no claim against the debtor’s fiancé or fiancée at the time the contract is concluded, then his rights cannot be infringed or affected in any way by the conclusion of the prenuptial agreement. The Supreme Court has admitted that the protection of third parties from the conduct of spouses intending to diminish the rights of creditors is also undoubtedly legitimate, but there is no rational argument that the creation of a marriage should lead to the possibility of foreclosure also on the spouse’s property acquired before the marriage.

Tip for article

Some bailiffs try to recover the amount owed from any available assets, sometimes going beyond the limits of pre-nuptial agreements. This may also be an unconscious practice that does not distinguish between what is included and excluded from the matrimonial property. If the conduct in question continues even though the executor has been informed of the contents of the prenuptial agreement, we recommend prompt intervention with the help of a lawyer. If you want to know how the bailiff should proceed and what you can do if you disagree with his/her actions, read our article on the subject.

Protection of creditors

The law protects not only spouses but also creditors. Therefore, spouses cannot simply “divert” assets in a marriage or pre-nuptial agreement in order to shortchange creditors. If one of the spouses has committed himself or herself in a period of less than six months, the creditor may, under the legal conditions, satisfy himself or herself even out of what would otherwise have been part of the community property if the change of regime had not taken place.

Similarly, if the change in the matrimonial property regime affects the right of a third party, in particular a creditor, that party may, in the cases provided for by law, claim protection as if the change had not occurred. The prenuptial agreement is therefore a powerful preventive instrument, but it cannot be seen as a means of frustrating the rights of creditors that already exist.

What if there is no prenuptial agreement?

If you have found yourself in one of the situations described above and are now wondering what to do if you did not think of a prenuptial agreement when you were single, you need not worry.

As we mentioned above, even during the marriage a similar agreement can be concluded and the matrimonial property can be reduced. This cannot be done retroactively to the marriage, of course, but it will apply to any property acquired after the marriage.

Even if you do not have a similar agreement, neither spouse is liable for the debts of his or her spouse with his or her sole property (i.e. inherited funds, gifts or property acquired before the marriage).

Summary

Marital debt is not to be underestimated. Marital property does not only mean jointly acquired assets, but in certain cases also joint liabilities. People should be particularly careful if they enter into a marriage with a partner who is already in debt, in business, liable for loans or in a financially risky environment.

A prenuptial agreement is the most effective prevention. If you are already married, a similar protection can be set up in a marriage contract and the community property can be narrowed for the future. However, the agreement must be drafted correctly and requires a notarial deed. In more risky situations, it is also worthwhile to register the deed in the Register of Marital Property Deeds as it increases protection against third parties.

However, neither the prenuptial nor the marriage contract serves to additionally relieve the spouses of pre-existing debts or to prejudice creditors. Therefore, it is best to deal with the property regime early – ideally before the wedding or as soon as a business or credit risk arises.

Frequently Asked Questions

Am I liable for my spouse's debts?

Not always. It depends on when the debt was incurred, for what purpose and whether it is part of the community of property.

Are debts incurred before the wedding part of the community property?

Debts incurred before the wedding are usually the sole debts of the one who incurred them. Nevertheless, in practice, they can cause problems in the case of execution or the disposal of joint property.

Will a prenuptial agreement help against foreclosure?

Yes, if it’s set up correctly. It provides even stronger protection if it is registered in the Schedule of Matrimonial Property Deeds.

Can we reduce the community property after marriage?

Yes. The spouses can conclude a marriage contract and reduce the community property for the future. However, this cannot retroactively eliminate debts that have already been incurred.

Does the prenuptial agreement have to be notarized?

Yes. Both the prenuptial and the marriage contract on the property regime require a notarial deed.

What if my husband took out a loan without my knowledge?

For larger debts outside the normal needs of the family, the debt may be the sole debt of the indebted spouse. However, it is important to act quickly and properly document the disagreement.

Can a bailiff seize my sole property?

It should not affect assets that are proven to belong only to you and are not part of the community property. In practice, however, it is often necessary to prove the origin of the property and, if necessary, to file a motion to exclude the property from the inventory.
