If you have a special preferential right in a real property unit it is called that the real property unit is attached.
When can you apply?
You can apply to get paid (order to pay) if someone is indebted to you. Your claim must be about money and the last date for payment must have passed.
We or a court may determine that your claim shall have special preferential right in the real property unit. The real property unit is then considered attached. This means you can request a sale of the real property unit. We can then sell the real property unit by way of execution and you get paid.
You can read more about how to do this on the website.
