Beyond risk flagging. Real-world enforceability.

Most contract review tools tell you whether a clause is risky for your business. That's your Playbook Score — and Vern does that too.

But the Vern Score goes further. It independently assesses each clause for enforceability under UK law, commercial viability, and practical outcomes. A clause might protect you on paper but be unenforceable in court. The Vern Score catches that.

Two lenses on every clause

Playbook Score — Does this clause protect your interests? Measured against your configured risk positions. Your business, your rules.

Vern Score — Is this clause enforceable, commercially standard, and practically viable? An independent assessment grounded in UK contract law and market norms.

Vern Score
Caution 45
A £10,000 liability cap for a professional services firm providing services potentially worth tens of thousands in fees is at the low end of commercial reasonableness. Under UCTA 1977 s.2(2) and s.3, limitation clauses must satisfy the requirement of reasonableness. Courts assess reasonableness by considering the parties' relative bargaining positions, whether the customer received an inducement to agree to the term, and whether the party relying on the term could have insured against the liability. A £10,000 cap may be challenged as unreasonably low, particularly for high-value engagements. However, the exclusion of consequential loss is standard and likely enforceable. The cap would likely survive judicial scrutiny if raised to 12 months' fees, but at £10,000 it is vulnerable to challenge.
How it works

Two scores, two questions answered

Playbook Score

Does this clause protect your interests? Measured against the risk positions you've configured in your playbook. Your thresholds, your rules, your risk appetite.

Accept Clause meets your configured position
Review Outside your ideal range, needs attention
Escalate Breaches your red lines

Vern Score

Is this clause enforceable, commercially standard, and practically viable? An independent assessment grounded in UK contract law and real-world commercial norms.

Strong Enforceable and commercially standard
Caution At the outer limit, may cause pushback
Weak Likely unenforceable in court

Why you need both

A clause can score "Accept" on your playbook but "Weak" on the Vern Score. That means it protects your interests on paper — but a court might not enforce it.

Conversely, a clause might "Escalate" on your playbook but score "Strong" on the Vern Score. The other party has a commercially standard position — you just need to negotiate better terms for your side.

The dual-score system gives you the nuance to make smarter decisions, faster.

Grounded in UK contract law

The Vern Score references real legal frameworks — UCTA 1977, common law principles, and established commercial standards. It doesn't just flag risk; it explains why a clause may or may not hold up.

Every Vern Score comes with a written assessment explaining the enforceability analysis, referencing the relevant legal principles and commercial context.

What makes it unique

No other tool does this

Independent assessment

The Vern Score is independent of your playbook. It evaluates enforceability objectively, regardless of your configured risk positions.

Written analysis

Every score includes a detailed written assessment explaining the legal reasoning, referencing relevant legislation and commercial context.

UK law grounded

References UCTA 1977, common law principles, and established commercial standards. Not generic AI guesswork — real legal frameworks.

Negotiation intelligence

Know when the other party's position is commercially standard (Strong) versus when they're overreaching (Weak). Negotiate from a position of knowledge.

Catches hidden weakness

A clause might look protective but be unenforceable. The Vern Score catches clauses that wouldn't survive judicial scrutiny.

Numeric precision

Every clause gets a numeric score (0-100) alongside the Strong/Caution/Weak rating. Track enforceability across your entire contract portfolio.
