the undersigned (I, me, we)

"The undersigned" is a fixed legal/formal phrase used in letters, contracts, and certificates. The key decision is not whether to use I, me, or we after it, but how the phrase fits the sentence: choose a verb or pronoun that matches the number of signers and keep wording clear for readers and courts.

Below are quick rules, concrete examples, rewriting tips, and common pitfalls so you can fix drafts fast.

Quick answer

Use a verb that agrees with the number of signers or rewrite the sentence to use an explicit pronoun or name. Avoid appending "I" or "me" directly after "the undersigned."

If one person signs: use a singular verb-"The undersigned hereby certifies...".
If multiple people sign: use a plural verb-"The undersigned hereby certify...".
If you prefer first person, rewrite: "I, the undersigned, hereby certify..." or list the names.

How "the undersigned" works

Grammatically, "the undersigned" is a noun phrase that stands in for the signer(s). It behaves like any noun: the verb must agree in number, and you shouldn't tack on a separate pronoun without restructuring the sentence.

Common mistakes come from trying to force a first- or third-person pronoun immediately after the phrase (for example: "the undersigned I" or "the undersigned me"), which distorts syntax and reads as an error.

When to use singular vs. plural

Decide whether the clause refers to one person or a group:

Single signer: use singular verbs and participles. Example: "The undersigned certifies that the information is true."
Multiple signers: use plural verbs. Example: "The undersigned certify that the information is true."
If the number of signers is unclear, rewrite to name the signers or use "we."

Hyphenation and spacing

Write "the undersigned" as two words. Do not hyphenate or join with underscores. "Undersigned" is one word when used without the article, but the common phrasing in documents is "the undersigned."

Correct: The undersigned hereby agree to the terms.
Wrong: the_undersigned; the-undersigned; theundersigned

Common grammar pitfalls

Watch two traps: verb agreement and misplaced pronouns. Also avoid ambiguous modifiers that leave it unclear who "the undersigned" covers.

Verb agreement error: "The undersigned hereby certifies" (wrong if multiple signers).
Misplaced pronoun: "The undersigned me" (ungrammatical).
Ambiguous reference: don't follow with a clause that could refer to someone else-clarify by naming signers or adding a parenthetical list.

Real usage examples

Formal (single signer): The undersigned hereby certifies that the statements above are true.
Formal (multiple signers): The undersigned hereby certify that they have examined the report.
First-person preference: I, the undersigned, declare that the foregoing is accurate.
Named signers: The undersigned-John Smith and Maria Lee-agree to the terms set forth herein.
Signature block (informal): Signed: John Smith (the undersigned).

Try your own sentence

Check the whole sentence, not just the phrase. Context reveals whether to use singular/plural verbs or to rewrite for clarity.

Wrong vs right examples you can copy

Wrong: The undersigned me hereby certify the facts.
Right: I, the undersigned, hereby certify the facts.
Wrong: The undersigned hereby certifies that all parties consent.
Right: The undersigned hereby certify that all parties consent. (if multiple signers)
Wrong: The undersigned hereby do confirm.
Right: The undersigned hereby confirm. (plural verb without an extra auxiliary)
Wrong: Signed: the_undersigned.
Right: Signed: the undersigned.
Wrong: The undersigned, we agree to the terms.
Right: We, the undersigned, agree to the terms.
Wrong: The undersigned hereby declares under penalty of perjury.
Right: The undersigned hereby declare under penalty of perjury. (if plural)

How to rewrite for clarity

When in doubt, make the signer explicit. That removes ambiguity and avoids awkward grammar.

Option 1 - Name the signers: "John Smith and Maria Lee, the undersigned, certify that..."
Option 2 - Use first person: "I, the undersigned, certify that..."
Option 3 - Use "we" up front: "We, the undersigned, agree to the following terms."

Rewrite example: Original: The undersigned hereby are responsible.
Rewrite: We, the undersigned, are responsible.
Rewrite example: Original: The undersigned hereby pays.
Rewrite: The undersigned hereby pays the sum due. (or: I, the undersigned, pay the sum due.)
Rewrite example: Original: Is the undersigned allowed to sign?
Rewrite: Is the undersigned authorized to sign? (or: Am I, the undersigned, authorized to sign?)

A simple memory trick

Think number first: ask yourself "How many signers?" If one, use singular construction; if more than one, use plural construction or name the signers. That single check prevents most errors.

Similar mistakes to watch for

Mixing singular/plural verbs with collective nouns.

Using underscores or hyphens in legal phrases.
Confusing "undersigned" with "signatory" or "subscriber" when a different nuance is needed.

FAQ

Can I use "I" after "the undersigned"?

Not directly. Either write "I, the undersigned, ..." or omit "I" and use the appropriate verb: "The undersigned hereby certifies..." (singular) or "...certify" (plural).

Is "the undersigned" singular or plural?

It can be either. The phrase itself is neutral; the verb and context determine number. Use singular verbs for a single signer and plural verbs for multiple signers.

Which is correct: "the undersigned hereby certifies" or "certify"?

Both can be correct. Use "certifies" for a single signer and "certify" for multiple signers. If you want to avoid the choice, rewrite to name signers or use "I"/"we" explicitly.

Is "undersigned" hyphenated or one word?

Write "undersigned" as one word when standing alone and "the undersigned" as the standard two-word phrase; do not use underscores or hyphens.

Should I rely on spellcheck for this?

Spellcheck may not catch verb-agreement or phrasing issues. Always read the full sentence and, when in doubt, rewrite to make the subject explicit.

Check the whole sentence before you send it

Small errors around "the undersigned" become obvious in context. Read the sentence aloud or rewrite the clause to include names or first-person pronouns; that fixes most problems and improves clarity.
