How to Review a Severability and Blue-Pencil Clause
Review a severability clause: savings job, strike vs reform, England and Wales rewrite limits, essential-term risk, then keep, add reform, or walk.
Key takeaway in 30 seconds
Knowing how to review a severability and blue-pencil clause means checking whether a failed term leaves the rest alive — and whether the paper asks a court to strike words or rewrite them. Under England and Wales colour, blue pencil is usually deletion, not a free rewrite desk. Test essential-term risk, fence entire agreement and no-waiver, then keep, add reform, or walk.
Mercer, Ops at a 20-person UK SaaS, is about to treat a reform-max severability line as a safety net while a worldwide non-solicit sits in the same packet — a hidden Friday risk. Knowing how to review a severability and blue-pencil clause is a short savings hunt: savings job → strike vs reform → governing law / restraints → essential term → fence entire agreement / no-waiver → keep / add reform / walk.
September 2026. English law; courts of England and Wales. The packet — the exact file set before Friday — has Clause 19 of the MSA — master services agreement — “If any provision is held invalid, the court shall modify it to the maximum extent permitted so the commercial intent survives.” Clause 12: worldwide customer non-solicit, no lookback. AE Slack: “Boilerplate — severability saves the deal. Sign Friday.”
A severability clause does not make an English court your free rewrite desk — and “modify to the maximum extent” may ask for more than blue pencil allows. Tillman v Egon Zehnder Ltd [2019] UKSC 32 (checked 2026-09-29): words may be severed if removable without adding or modifying what remains, and removal must not generate a major change in the overall effect of the restraints. Gowling WLG on the blue pencil test: a court can sever words; it will not rewrite an overbroad restriction into a valid one.

What does the savings clause actually do on review?
Severability — sometimes called a savings clause — tells a court that if one provision fails, the remaining provisions should continue. It is evidence of intent, not a guarantee the leftover paper still works.
Do: open Clause 19 and log the exact savings sentence. Don’t: treat “boilerplate saves the deal” as automatic survival of every term. Concord on severability clauses (checked 2026-09-29): evidence of intent, not conclusive; cannot revive a term public policy prohibits. Hall Ellis on severance clauses: savings language sets the intended procedure when a court rejects bad parts.

How do you tell strike-only from a reformation ask?
Strike-only language asks a court to delete invalid words or a provision. Reformation language asks the court to modify or narrow terms so commercial intent survives. Different outcomes on Friday’s paper.
Do: classify Clause 19 as strike-only or reform-max before Finance signs. Don’t: assume “modify to the maximum extent” equals English blue-pencil deletion. veqtor.pro on English severability (checked 2026-09-29): under England and Wales colour, severance operates by deletion; the court will not rewrite a provision to save it. For example, Mercer’s Clause 19 is a reform ask next to a worldwide non-solicit that needs deletion-friendly drafting, not hope.
Typical mistake
AE sells free rewrite while Clause 12 is worldwide — log reform-max + restraint as one package.
Review governing law before you trust rewrite hope
Governing law decides whether a court will rewrite — especially restraints. Name England and Wales. Tillman blue-pencil colour is a limited lifeline: delete clean words, do not invent a narrower covenant.
Do: read Clause 12 with Clause 19 and ask whether offending words can be struck without rewriting. Don’t: leave a worldwide non-solicit because severability “covers it.” RPC on blue-pencil severance restates Tillman’s three criteria, including no major change in the overall effect of the restraints. Arthur Cox on Tillman: tailored drafting beats severance as the cure. Escalate rewrite hope to counsel — a qualified lawyer, not the chatbot — and do not invent a High Court outcome.

Check essential-term risk before you keep leftovers
Essential-term risk is when the invalid piece is the commercial heart — price, exclusivity, core IP licence, or the main performance promise. Severing it can leave paper that is no longer the bargain.
Do: ask whether the leftover MSA still looks like Friday’s deal if Clause X fails. Don’t: assume savings boilerplate keeps an empty shell alive. Concord colour: if the struck provision was central, a court may refuse to enforce the remainder. Clayton Utz on severance (AU colour only, checked 2026-09-29): interdependent clauses can block severance — fence as not England-and-Wales statute, same warning. A typical mistake is logging “severability present = risk closed” without testing the heart of the deal.
When to fence entire agreement and no-waiver
Entire agreement / merger / no-reliance and no-waiver / waiver by conduct are different boilerplate hunts. Stay on severability here; send those fights to their own checklists.
Do: one-sentence fence, then return to Clause 19. Don’t: rewrite merger or waiver while reform-max + worldwide non-solicit sit unsigned. Entire agreement is how to review an entire agreement and no-reliance clause. No-waiver is how to review a no-waiver clause and waiver by conduct. This article is savings + strike vs reform only.

When to keep, add reform for covenants, or walk
Keep when savings matches deletion reality and restraints are tidy. Add reform for covenants with an express mutual ask — and still draft so deletion can work. Walk when AE sells free rewrite plus a worldwide non-solicit.
Success bar: one-page log plus one Friday pause sentence (Clause 19 vs “boilerplate saves the deal,” Clause 12 open). Workflow: savings job → strike vs reform → governing law / restraints → essential term → fence B44/B99 → keep / add reform / walk. Optional: upload the same PDF to document analysis for a first-pass — first machine pass extracting clauses — then a named human opens Clause 19 and Clause 12. Verify every High flag — high-severity item a named human still opens. Escalate to counsel. Never treat the paper as ready to countersign.
Mercer’s severability log
| Check | Mercer’s paper | Action |
|---|---|---|
| Savings job clear? | Clause 19 present | Log exact sentence |
| Strike vs reform? | Modify to max extent | Treat as reform ask |
| Governing law? | England and Wales | Blue pencil = deletion colour |
| Restraint rewrite risk? | Worldwide non-solicit | Narrow or walk — don’t rely on savings |
| Essential term if struck? | Not tested yet | Test price / exclusivity / core IP |
| B44 / B99 fenced? | Wrong hunt risk | One sentence each; stay here |
| Decision | AE: boilerplate saves deal | Add reform + tidy restraint, or walk |
Hunt
Freeze the packet
MSA severability + restraints + governing law. Search sever / savings / modify / reform. Fence entire agreement and no-waiver if those are the real fights.
Confirm the savings job
Log whether remaining provisions continue when one term fails. Intent evidence, not a guarantee.
Classify strike vs reform
Strike-only deletes. Reform-max asks a rewrite. Mercer’s Clause 19 is reform language — not blue-pencil-only.
Name governing law and restraint limits
England and Wales colour: deletion, not free rewrite. Open Clause 12 with Clause 19.
Test essential-term risk
If price, exclusivity, or core IP fails, does the leftover bargain still work? Illegality is not cured by savings boilerplate.
Fence B44 and B99
One sentence each with live sibling links. Return to severability.
Keep, add reform, or walk
Fill the log. Pause Friday if AE insists the court will fix anything while the non-solicit stays worldwide.
