My ex does not want to cooperate in selling my house

Questioner

About half a year ago I bought a house with my then partner. We have to sign the deed of transfer at the end of April and will receive the key to our house. We have separated and I would like to put the house back up for sale as soon as possible. He does not want to cooperate and even wants to have furniture delivered to the house and live there until he has found something else. While he may just have a place to sleep. What can I do about this? He also does not want to contribute the money to the house, because he would contribute money and we also have a mortgage together. He wants to have a promissory note signed, but I do not want this. He will immediately seize my account and demand the money immediately while the house has not yet been sold, for example.

Lawyer

Dear, you should (first) contact your ex by email/writing and ask if he cooperates with the sale (so that you have proof of this) and if he still does not cooperate, then you can ask the judge to oblige your ex to cooperate. You can also ask the judge (until the house is sold and as long as your ex uses it) to give you at least a usage fee. Of course I am happy to help you with this.
