Legal documents are designed to be precise — but too often, they're written in a register that only lawyers can parse. "Hereinafter", "notwithstanding the foregoing", "party of the first part" — these phrases carry meaning, but they also gatekeep. If you can't read your own lease, your own terms of service, or your own employment contract, you can't make informed decisions.

This guide covers how to simplify legal documents into plain English without losing the meaning that makes them legally binding.

Why legal jargon exists (and when it's a problem)

Legal language has a real purpose: it's the product of centuries of precedent. "Hereinafter" means "for the rest of this document" — once. "Notwithstanding" means "despite what we said earlier". These words compress complex conditional logic into short phrases.

The problem isn't that the words exist. The problem is when the reader isn't the legal author. If you're signing a contract, you need to understand it. If you're a compliance officer, you need to explain it to non-legal staff. If you're a consumer, you need to know what you're agreeing to.

That's where simplification comes in — not to replace the legal text, but to produce a plain-English companion version that anyone can understand.

The 4-step method for simplifying legal text

1. Read the whole document first

Don't simplify clause-by-clause as you read. Legal documents build on earlier definitions. A phrase in clause 7 might reference a definition in clause 2. Read the whole thing, then simplify.

2. Replace archaic connectors

"Hereinafter" → "in this document" "Notwithstanding" → "despite" "Hereby" → "by this" "Pursuant to" → "under" "Aforesaid" → "mentioned above"

These substitutions don't change the legal meaning. They remove the friction.

3. Break long sentences into short ones

A typical contract sentence runs 40-80 words with nested clauses. Break it:

"The Party of the First Part shall, upon receipt of written notice from the Party of the Second Part, within thirty (30) days of such receipt, remit payment in full."

Becomes:

"When Party B sends written notice, Party A must pay in full within 30 days of receiving it."

4. Check the reading level and re-simplify

Run the simplified text through a readability check. Aim for grade 5-6 (Flesch-Kincaid). If the result is above grade 6, the text still has jargon or long sentences — iterate.

This is the step most people skip. Simplification isn't a one-pass rewrite. You simplify, measure, and simplify again until the readability score drops to the target level.

Tools that automate the process

You can do all four steps by hand. For most people, that's too slow.

ELI5 AI (https://eli5.team19.xyz) automates the whole pipeline: paste legal text, get a plain-English version at a 5th-grade reading level, with the readability score measured and re-simplification applied automatically if the result is above grade 6. No login, no storage, no paywall.

The key advantage over generic AI chat tools: ELI5 AI measures the output. It doesn't just claim the text is simpler — it checks the Flesch-Kincaid grade level and re-runs the simplification if the first pass didn't reach the target. That measurement loop is what separates a text simplifier from a text rewriter.

What simplification can and can't do

Can do:

• Produce a plain-English companion version of a legal document
• Make contracts readable for non-legal staff, clients, or consumers
• Speed up the review process — you understand the document before your lawyer does
• Help compliance teams train new staff on what a policy actually says

Can't do:

• Replace legal advice — always have a lawyer review the original, not the simplified version
• Change the binding text — the simplified version is for understanding, not for signing
• Handle every edge case — some legal language is dense because the underlying law is dense

The safe workflow: simplify for understanding, then refer to the original for any legal decision.

Key takeaway

Legal documents don't have to be unreadable. The same content can be expressed at a 5th-grade reading level without losing its meaning — you just need to measure the result and iterate until it's clear. That's what a readability-verified simplifier does.

Try it on your own contract: paste a clause into ELI5 AI and see the reading level drop.
