ONYST RVG
ChatGPT pluginGerman legal fees (RVG)
ONYST RVG connects ChatGPT to the fee engine behind the ONYST fee calculator for German lawyers. ChatGPT no longer estimates fees under the German Lawyers' Remuneration Act (RVG): it asks the engine, and every item comes back with its fee number (VV), rate and calculation.
What you can do:
- Calculate fees, expenses and VAT for a matter, or for several matters with credits between them, for example a payment order procedure followed by a lawsuit.
- Determine the value in dispute, for example for tenancy, maintenance or dismissal cases.
- Look up fee numbers, rates and required inputs in the fee schedule.
- Find the route between two addresses for travel expenses, with a map and the distance as an expense item.
- See an invoice as a draft in your firm's layout, then issue it as PDF or e-invoice (ZUGFeRD), along with a calculation sheet. Documents arrive as a download link that is valid for seven days.
- Find recipients in your address book and read or update your firm's invoice details. ChatGPT asks before every change.
Results appear as interactive views in the chat: the calculation, the value in dispute, the fee schedule, the route, the invoice draft with its pages, the finished invoice and the documents to download.
Who it is for: law firms and legal departments in Germany. You sign in with your ONYST account; new users can create one during sign-in. The calculation tools work with every ONYST account. Whether invoices, calculation sheets and the distance for travel expenses are available depends on your firm's ONYST account.
Limitations: ONYST RVG calculates lawyers' fees under the RVG; it does not calculate court fees. The results are a calculation, not legal advice. Whether a fee applies in the individual case and whether a discretionary rate is appropriate remains the lawyer's responsibility.
Your control: every connected assistant is listed in your ONYST account under Connected assistants and can be disconnected there at any time. Download links can be withdrawn in the invoice history.
