Delete land registry entry from the developer

I don't know of any debts that would not be statute-barred after 20 years. This applies at least to the 1st deduction. The 2nd part is not yet due.

It's not that simple...

2nd part is not yet due. But since the bank can no longer meet the condition for maturity, they are practically also statute-barred. Layman's opinion!

Also not that simple. 2nd part is not yet due, so why should the bank then grant a deletion approval? It will be a legal tug of war.

Tip: See a lawyer. Unfortunately, the partial purchase price saved back then is now financially catching up with you at least a little.

Layman's opinion!

Reminders interrupt statutes of limitations, and after obtaining a title, the claim remains valid without further reminders for 30 years.

Reminders interrupt statutes of limitation, and after obtaining a judgment, the claim remains statute-barred for 30 years without further reminders.

That was not an official dunning procedure back then, and certainly no judgment. It was a letter shortly after the payment of the due purchase price, stating that I should still pay the deducted amount. I had previously threatened the bank with damages.

I wanted to report the current status. After I called the notary, they contacted the successor bank. Since the bank supposedly no longer had any documents and no claims against me, they are sending the cancellation approval. Since the developer no longer exists, I have to sign at the notary in their place. Apart from the fees at the land registry office, the whole process is free for me. I also wanted to have the mortgage of my financing canceled at the same time to save time and money. Since the loan runs until September, Sparkasse refuses to issue the cancellation approval, although the outstanding amount is very low, and they also refused early repayment because it was not agreed upon.

Then just wait until your remaining debt is paid off. Whether the release authorization from the successor bank sits in your file (or with the notary) for a year or is implemented immediately doesn't matter to you. You have it! I also had a release authorization for a right of way here (because the lines have not run under the property for 40 years) lying around for 2 years until the discussion/negotiations about the deletion of a repurchase right were completed.

Since the loan is still running until September, the Sparkasse refuses to issue the cancellation approval even though the outstanding amount is very small

I don't see what's special about that. The loan is still running after all. The collateral could then, for example, no longer be used for refinancing through a covered bond = condition surcharge x%. In addition, contracts must be adhered to.

They also refused the special repayment because it was not agreed upon.

Also normal. Would you simply accept an interest rate increase just because the bank feels like it?
