What happens if a partner dies: legal challenges for unmarried couples.

If a couple cohabits, shares property, household expenses, loans, and even raises children without formalizing their marriage, their relationship is legally regarded as the cohabitation of two distinct individuals. While the emotional connection may be as strong as that of married couples, the legal implications differ significantly.

If a house, car, or other property that both partners used is registered solely in one partner’s name, that individual is the legal owner of the property. Even if the other partner made financial contributions, provided labor, or took out loans, they do not automatically acquire co-ownership rights. Upon the death of the partner whose name the property is registered under, the property will be transferred to the heirs designated by law—typically children, parents, or siblings, unless a will has been made.

The surviving partner, despite having lived together for many years, does not have inheritance rights unless a will specifically names them as an heir or if there was a pre-arranged property division (such as through a notarial agreement or property transfer during the lifetime of the deceased).

If the property (e.g., real estate) is registered in both partners’ names, it is considered joint property. Upon the death of one partner, their share is inherited according to the legal succession order. In this case, the surviving partner continues to be a co-owner alongside the deceased partner’s heirs (such as children, parents, or other legal heirs). This scenario can lead to various practical and emotional challenges, particularly when the surviving partner must make decisions in collaboration with the deceased’s relatives, who may not be supportive or closely involved in the relationship.

If the loan is taken out in both partners’ names – such as a mortgage agreement where both are listed as borrowers – they are considered joint debtors. In the event of one partner’s death, the surviving partner assumes full responsibility for the loan obligations, unless alternative arrangements were made with the bank or financial institution (e.g., modifying the agreement to include a new co-borrower or guarantor, applying insurance benefits, or other protective measures).

If the loan or lease is only in one partner’s name, the obligations incurred by the deceased partner transfer to their heirs. Therefore, unless a will was made naming the surviving partner as an heir, the surviving partner holds no legal responsibility to the deceased partner’s creditors. However, they also have no entitlement to claim any property or assets unless specific agreements about joint use or ownership were in place.

For unmarried couples building a life together, it is essential to establish a clear legal foundation in advance:

• Will: The only way to ensure that your partner can inherit your property. Without a will, inheritance rights do not arise solely from cohabitation.

• Joint Venture Agreement: A notarized agreement that outlines how property, loans, and investments will be managed, who owns what, and how matters will be handled if the relationship ends or if one partner passes away.

• Life Insurance with a Beneficiary: If the partner is named as the beneficiary, they can receive financial support regardless of inheritance laws.

• Gift or Transfer of Property: During your lifetime, you can arrange for the transfer of property to your partner, ensuring their legal security in the future.

Why is it important to address this in advance?

Many couples still believe that long-term cohabitation automatically creates certain legal rights. However, legal protection only occurs when couples take proactive steps, such as signing agreements and drafting key documents. Without these, even someone who has lived together for many years may find that, upon the death of their partner, they have no legal right to remain in the shared home or claim inheritance.
