Assignment Clause Adversarial Test (German AGB Law)

Reviews, redlines and rewrites assignment (Abtretung) clauses in standard terms under German AGB law, with a risk traffic light and fallback wording.

What it does

  • Audits assignment (Abtretung) clauses in standard business terms against BGB §§305–310 and the UKlaG collective-action risk.
  • Forces a fixed review path: AGB status → incorporation (§305) → surprising clause (§305c) → transparency (§307(1)) → content control (§§307–309) → legal consequence (§306).
  • Deliverables: clause traffic light, redline, safe replacement wording, negotiable fallback, and a short court-proof justification.
  • Flags deadlines first (objection, action, limitation, forfeiture, notification/cut-off periods) and forbids importing deadlines from other legal fields.
  • Builds an evidence matrix: original clause, contract context, proof of use, negotiation traces, customer group, market standard, economic effect.

Who it's for

  • Lawyers and in-house counsel reviewing German AGB / T&Cs.
  • Startups and SaaS vendors entering the German market drafting B2B/B2C terms.
  • Law students training clause-review reasoning under German law.

Example uses

  • "Is this no-assignment clause in our supply agreement invalid under §307 BGB?" → rating, consequence, replacement text.
  • "Redline the B2C clause 'we may freely assign our contractual rights to third parties'" → surprise/transparency findings plus a consumer-safe version.
  • "The counterparty objects to our assignment clause — give me fallback wording and counter-arguments."
