A court-appointed legal guardian responsible for financial affairs may sell a property belonging to the person under guardianship, but as a rule requires the approval of the guardianship court (§ 1850 BGB). Until that approval is final, the purchase contract remains provisionally ineffective. The court examines the person's wishes, whether the price is appropriate and the welfare of the person under guardianship, usually on the basis of a valuation report.

When a legal guardian may sell a property
The prerequisite is that the guardian has been assigned the area of responsibility for asset management (Vermögenssorge, or explicitly "housing and property matters"). Being appointed guardian is not enough on its own: the guardianship court must have ordered the appropriate area of responsibility.
There must also be a comprehensible reason: often pension and assets are not enough to finance a care home place permanently, and the sale proceeds are meant to secure the care. Other reasons can be high, unaffordable renovation costs or the express wish of the person under guardianship, provided they still have legal capacity.
Approval by the guardianship court (§ 1850 BGB)
The crucial point: to sell a plot of land or an apartment, the court-appointed legal guardian generally requires the approval of the guardianship court. Until this approval is legally final, the notarised purchase contract is provisionally ineffective, meaning it has no legal effect yet.
The court examines two things: whether the sale is in the best interests and, as far as possible, in line with the wishes of the person in care, and whether the price is appropriate. The property must not be sold below value. Such sales are usually decided not by a judge but by a judicial officer (Rechtspfleger).
The valuation report, the heart of the procedure
For the court to assess whether the price is appropriate, verifiable evidence of value is required. The legal guardian must show the court at what price the property is to be sold and why this reflects the market. A properly documented, market-based valuation is therefore not an extra, but the foundation on which the approval rests.
The process step by step
- Check the scope of duties Does the certificate of appointment cover financial or property matters?
- Document the reason for the sale A written explanation to the court of why the sale is necessary and sensible.
- Determine the value A market-based, verifiable valuation of the property as the basis.
- Buyer and purchase contract Marketing, buyer selection, notarised purchase contract, initially provisionally ineffective.
- Apply for approval The court examines the price and the interests of the person under guardianship and grants approval (in practice often four to eight weeks).
- Completion The contract only takes effect once the approval is final; the notary presents it on completion.

Frequently asked questions
May a legal guardian sell a property without approval?
No. For plots and apartments, the guardian generally needs the approval of the guardianship court (§ 1850 BGB). Without it, the purchase contract is provisionally invalid.
How long does the approval take?
In practice, often around four to eight weeks. The court examines whether the sale is in the interest of the person under guardianship and whether the price is appropriate.
What happens if the property is sold without approval?
The contract remains provisionally ineffective until the approval is final. If the guardian acts in breach of duty, they are liable to the person under guardianship for any damage.
May a property be sold against the wishes of the person under guardianship?
In principle, the legal guardian must act in accordance with the person's wishes. If these run counter to the person's welfare, for example because the proceeds are needed for care, the court may nevertheless approve the sale in individual cases.
Which documents does the guardianship court need for a house sale?
As a rule, a written justification for the sale, verifiable evidence of value and the notarised purchase contract or its draft. On this basis the court checks whether the price and the sale are in the interests of the person in care.
Can a relative who is the legal guardian sell the house?
Yes. Whether a volunteer guardian from the family or a professional guardian, the same rules apply: the appropriate scope of duties and the approval of the guardianship court are required.
