How to Initial a Document: Where, When and Why

To initial a document means to write the first letters of your names, usually in the margin or at the foot of a page, to show that you have seen that page or agree to a particular change. It is quicker than a signature and it does a different job. This guide explains where initials go, how to initial an amendment, when initials are not enough, and what to do if you are initialling on a screen.

What does it mean to initial a document?

Initials are the first letter of each of your names, written by hand. Someone called Amelia Jane Hart would initial "AJH", or often just "AH" if she has no use for a middle name. Most people write them in a short, fast version of their signature style, so they look the same every time.

On a contract or form, initials normally mean one of three things:

• "I have seen this page." Initials at the foot of every page of a long agreement.
• "I agree this change." Initials next to a crossed-out word, an added line or a corrected figure.
• "This is the page I was shown." Initials that make it harder to swap a page after signing.

You will also hear "to initial" used for approving an internal memo or a delivery note, which is the same idea: a quick mark that says "seen and agreed" without the weight of a full signature.

Initials vs a full signature

The law does not draw a hard line. A signature is any mark you make to show that you intend to authenticate a document, and for deeds the statute says that to "sign" includes making your mark¹. So initials can count as a signature if you meant them to. The Law Commission likewise treats the intention to authenticate as the core of the matter².

In practice, though, the two have different jobs:

	Initials	Full signature
Usual meaning	Seen, checked or agreed	Agreed to the whole document and bound by it
Where	Every page, margins, next to changes	The signature block on the last page
Time	A second	A deliberate act, often with a witness
Enough on its own?	Rarely, and never when a form asks for a signature	Yes, subject to any formalities

The safe rule: if a document has a signature block, sign it in full. Initials alone are a risky substitute, because the other side may later say you never meant to be bound. If you are unsure how your own signature relates to your initials, our guide to changing your signature may help.

When should you initial?

Every page of a long agreement

There is no general rule in England and Wales that every page of a contract must be initialled. The signature on the execution page is what counts. Lawyers still ask for it on tenancy agreements, loan terms, lease schedules and settlement agreements, because it is cheap evidence that each party saw the same pages. If the contract says "initial each page", then do so, since it is part of what you agreed to.

Handwritten changes

Any time a typed document is corrected by hand, each party should initial next to the change. Without that, the other side can argue that the alteration was added later. This is the single most useful reason to initial anything.

Forms, schedules and attachments

Plans, price lists, inventories and terms and conditions attached to an agreement are often initialled so that nobody can later claim a different version was meant.

Internal approvals

Invoices, timesheets, delivery notes and internal memos are often initialled to show that a named person checked them. This has nothing to do with contract law, but the habit is the same: be consistent and write the date next to the initials if the process asks for it.

How to initial a document step by step

1. Read the page first. Initialling something you have not read defeats the point, and may undermine you later.
2. Use the same pen colour as the rest of the signing, black or dark blue ink.
3. Put initials where the document asks, usually the bottom right corner, inside the marked box if there is one. If nothing is marked, use the foot of the page.
4. Initial next to each amendment, not at the end of the paragraph, so it is clear which change you mean.
5. Date the change if it matters. Date it if the document is long-lived or the changes are made after the main text was prepared.
6. Make sure every party initials. A one-sided mark proves little.
7. Keep a copy of the initialled pages before you hand over the original.

Initialling amendments

When a contract is changed by hand after it is printed, the usual method is:

• Draw a single line through the old words so they stay readable.
• Write the new words just above or beside them.
• Each party writes their initials (and often the date) next to the change.
• For anything big, such as a price or a term, retype the page and have it signed again.

Do not use correction fluid, and do not scribble over the text. A visible, initialled strike-through is evidence of what was agreed. A disappearing word is not.

Wills and codicils

Wills have their own strict rule. Section 21 of the Wills Act 1837 says that an alteration made after the will was executed is not valid unless it is executed like the will, but the section also accepts the signatures of the testator and the witnesses near the alteration³. In practice, initials in the margin by the testator and both witnesses are the usual way. Because one mistake can invalidate a gift, do not amend a signed will by hand without advice. A solicitor will normally draw up a codicil or a fresh will, and the full witnessing steps are in our guide to witnessed and certified signatures.

Deeds

A deed must be properly signed and witnessed under section 1 of the Law of Property (Miscellaneous Provisions) Act 1989¹. Initials in the margin do not replace that. They are only a helpful extra for handwritten changes made before signing.

When initials are not enough

• The form asks for a signature. Initials will often be rejected.
• Deeds, wills and lasting powers of attorney. They have set formalities, discussed in our article on the wet signature.
• Signing for someone else. Use the proper authority wording, as in our guide to the pp signature, not your own initials alone.
• Banks and ID checks. They compare against a specimen signature, not initials.

Initialling on screen

Many e-signing tools let you add initials as a typed or drawn mark. That works in the same way as any simple electronic signature: valid for most ordinary documents if you meant it, but it is not a qualified electronic signature. For a drawn mark, a clean image helps, and our guide to adding a signature to a PDF shows how to place one. The same rules apply as on paper: read the page, then initial.

Scotland

Scots law has its own rules on how documents are signed and witnessed. Whether a document is validly signed turns on the signature and witness details, not on page initials. The statutory presumption of valid signing is in section 3 of the Requirements of Writing (Scotland) Act 1995.

Not legal advice. This article describes the general position in England and Wales as of October 2026, with Scotland noted where it differs. For a specific document, ask the person or body that will receive it, or a solicitor.

Frequently asked questions

Do I have to initial every page of a contract?

Not by law in England and Wales. The signature on the execution page is what binds you. Initialling each page is a common safeguard, and you should do it if the contract asks.

Are initials legally binding?

They can be, if you meant them as your signature. Because the law looks at intention, initials alone can be risky, so sign in full wherever there is a signature block.

How do I initial a handwritten change?

Strike through the old words so they stay readable, write the new words beside them, and have every party write their initials (and ideally the date) next to the change.

Can I initial a will change?

A change to a signed will must be executed like the will. Initials by the testator and both witnesses next to the change are the usual method, but a solicitor should draw up a codicil.

What is the difference between initials and a signature?

Initials usually mean "seen or agreed", a signature means "I am bound by this whole document". Initials are shorter and are not a substitute where a signature is asked for.
