Is an E-signature Valid on a Lease Contract?

The short answer is yes: Philippine law recognizes electronic signatures. Under the country's electronic commerce law, an electronic document and an electronic signature are not denied legal effect merely because they are not paper and ink, and the rules on electronic evidence set out how courts receive them.

But there is a more useful question than "is it legal": can you prove it when someone denies it?

What you are actually proving

When a contract is challenged, three things are examined:

1. Who signed. Is there evidence that this person held the email or the link, and did they pass some check to get in?
2. Did they agree. Was there a clear step where they accepted the document, rather than merely scrolling past it?
3. Was it altered afterwards. Is the copy you hold today exactly the copy they signed?

Good e-signing answers all three by itself. A photo of a signature pasted into a Word file answers none of them.

What the system should record

This is what to look for in whatever you use:

• How the signer was verified: a link sent only to them, and ideally a one-time code by email before signing
• Date and time the document was opened and signed
• IP address and device used
• A hash of the document before and after signing, so you can show it was not swapped
• A full record of every step, which cannot be edited afterwards

Without these, what you hold is a PDF with a picture of a signature on it. That is weak.

When you still want a notary

A notary does not make your agreement valid. The contract is valid because the two of you agreed. What notarisation does is make it a public document: heavier in court, and required for certain transactions.

Have it notarised when:

• The term is long and you intend to register it with the Registry of Deeds
• The amount or the deposit is large
• A partner, bank or office asks for a notarised copy
• You expect a dispute and want the stronger document

Under current Philippine practice, notarisation generally requires personal appearance. The practical path is to sign electronically so the tenancy can start, then notarise the printed copy when you meet. Our guide to notarising a lease goes further.

The practical flow

This is what works for most small landlords:

1. Send the contract to the tenant's email, with a link that is theirs alone
2. Have them read and sign electronically, ideally with a code sent to their email first
3. When everyone has signed, a final PDF is produced with the signing record attached
4. Send a copy to each party, and keep your own
5. If needed, print two copies and notarise when you meet

Do not edit the PDF afterwards. If something is wrong, issue an addendum. Changing a signed document is precisely what destroys its value.

Common mistakes

• A pasted signature image. Nothing shows who pasted it.
• One link shared by two people. You cannot show who signed.
• No copy for the tenant. A contract held by only one side is weak.
• The PDF edited afterwards. Even a small correction breaks the hash match.
• No written terms. A signature is worthless if what was signed is unclear — see our guide to the lease contract.

How MagpaUpa helps

In MagpaUpa each signer gets their own link and a one-time code by email before they can sign. Every step is recorded — when it was opened, when it was signed, from which IP address — and that record cannot be changed afterwards. The document is hashed before and after signing, so you can show it was not swapped. Once everyone has signed there is a final PDF with the record attached, ready to print and notarise. The tenant can also see in their own portal when they signed and from where. Try MagpaUpa.
