How do I find decisions on the compulsory share (§ 2303 BGB)?

Set the cited_norm filter to "§ 2303 BGB". For the supplement after gifts, use "§ 2325 BGB". Every decision comes with case number, court and date.

Are decisions of the higher regional courts included?

Yes. The higher regional court (OLG) hears appeals against the probate court, for example in certificate of inheritance proceedings. 1,800+ decisions in this area come from higher regional courts.

What does access cost?

Every call uses credits from your organization's balance, the same one the web app uses. A search costs 1 credit. The table above lists the price per tool. Your first organization receives 30 credits once, valid for 30 days.

How do I connect Claude, ChatGPT or Cursor?

Add the MCP address on this page as a custom connector. Claude and ChatGPT sign in with OAuth. Cursor and your own agents use an API token. The MCP documentation lists the steps for each client.

Are the case numbers in the answers real?

Every case number Klaracase returns points to a decision in the corpus, with court and date. You can fetch and read the full text at any time. The legal assessment stays with you.
