Powers of attorney and agreements with the highest legal standing — For you and your clients, with no paper and no meetings.
Law firms and legal departments handle powers of attorney, agreements and settlements that cannot tolerate the slightest gap in proof. Wthaiq brings everything these documents need into a single flow: the advanced signature (AES) with identity verification — the highest level the platform provides by itself — support for qualified signing (QES) with the client's own token and a certificate issued by a licensed certification authority they deal with directly, permanent legal standing, and multi-party signing. So you and your clients sign with no paper and no travel.
Identity verification is an optional add-on you choose when sending. One unit is charged for each signer it is requested for, from a credit balance separate from your plan.
In legal work, proof is everything.
It is not enough for a party to sign the power of attorney or the settlement; you have to prove who signed, when they signed, and that the document has not changed by a single letter since. Paper signatures and basic solutions leave gaps in legal standing that weaken the client's position against any judicial challenge or dispute.
Legal standing in dispute
A power of attorney or a settlement without a qualified signature and verified identity stays open to denial. Proving who signed and when, and that the copy was not swapped, turns into an exhausting procedural battle that drains time and weakens your client's position.
Stalled multi-party signatures
Agreements and settlements need signatures from parties spread across different locations, in a set order. Passing paper copies or PDF files around by hand confuses tracking, delays completion by weeks and opens the door to conflicting versions.
The client's trust is on the line
Clients want to sign remotely with complete confidence, and to verify the validity of any document they signed at a later date. The absence of a clear verification reference and a documented log undermines that confidence and burdens the firm with endless reviews and phone calls.
One system that carries every document to the highest levels of legal standing.
From the power of attorney and the engagement letter through to the settlement and the non-disclosure agreement — every document in the sector passes through the right layer of identity verification, qualified signing and authentication, so it stands up to any challenge.
Qualified QES signing with the client's own token
For powers of attorney, settlements and high-impact agreements, the parties sign with a qualified electronic signature using a token the party holds themselves, carrying a certificate from a licensed certification authority they deal with directly — we do not issue that certificate and its key never passes through our servers. Our role is to embed their signature in the file and preserve it at LTA level. The highest we offer by ourselves is the advanced signature (AES) with identity verification.
Identity verification for every signer
Each party authenticates their identity with an official document and a live face match before signing, so the signature is tied to a confirmed person rather than to a name someone typed in. The verification result is attached to the document, so doubts about who actually signed disappear. This verification is an optional add-on: when sending, you choose which signers are asked to complete it.
Multi-party signing in order
Set the parties to the agreement or the settlement and their signing order, and the system sends the invitations one after another and tracks each signature live. No manual exchange of copies and no version confusion — one trusted copy that everyone signs, wherever they are.
PAdES standing up to LTA level with a token
Documents signed with a token are sealed in the PAdES format, up to long-term archiving level (LTA), with timestamps and revocation data embedded, so the validity of the signature can still be proven many years after signing, even after the certificates expire.
An audit trail and a completion certificate
We log every event with its timing: opening the document, verification, signing, and delivery, with a digital fingerprint (HMAC-SHA256 for platform contracts, SHA-256 for uploaded PDFs) that reveals any modification. Each document gets a signed certificate of completion, giving you a complete evidence file ready for any court or arbitration body.
A public verification page
Every signed document has a public verification link showing the signing status, the parties' identities and the integrity of the copy. Your client or the receiving body confirms the document is genuine in seconds, without going through the firm — instant trust that strengthens your standing.
Value measured by the strength of the proof not by the number of pages.
Four steps from draft into a binding document that cannot be denied.
One connected flow that begins with preparing the power of attorney or the agreement and ends with a document signed by every party, archived with its evidence and with a verification page ready to go.
Preparing the document
The firm creates the power of attorney, the engagement letter or the settlement, and sets the parties and the signature fields in a single editor.
Identity verification
Each party authenticates their identity with an official document and live face matching, so their signature is tied to a confirmed person before any signing takes place. This step is optional: only the signers you request it from when sending go through it.
The parties sign
Each party signs in the set order: with the advanced signature (AES) backed by identity verification, or with a qualified signature (QES) using their own token for high-impact documents.
Legal standing and verification
The document is sealed with a signing record, a completion certificate and an audit trail, and in PAdES format up to LTA for anyone who signs with a token, and becomes verifiable through a public page.
Built for the highest legal standing — for you and your clients.
Six pillars that make Wthaiq the trusted choice for law firms and legal departments — for their own internal work and their clients' documents alike.
The strongest standing, with a qualified signature
A qualified electronic signature via a token issued by a licensed certification authority — the highest degree of legal force, made for powers of attorney, settlements and agreements that leave no room for denial before a court or an arbitral tribunal.
A verified identity for every party
Verification with an official document and a live face match ties every signature to a confirmed real person, proving who signed beyond doubt and cutting the risk of impersonation in powers of attorney and engagement letters from the very first moment.
Lasting legal standing that survives time
For token signatures, the PAdES-LTA format carries trusted timestamps and revocation data that keep the signature verifiable for many years, so proof of a power of attorney or a settlement holds up however long the dispute runs.
An audit trail and a completion certificate
A unified, timestamped record of every event in the document's life, with a signed completion certificate and a cryptographic fingerprint — so the evidence file is ready at once for any court or arbitration body, with no digging through emails or scattered copies.
Multi-party signing
A clear signing order and live tracking for every party, however far apart they are. One trusted copy signed by everyone remotely, so agreements and settlements are concluded in days instead of weeks, with no conflicting versions.
Public verification that builds trust
Every document has a public verification page that lets the client or the receiving body confirm in seconds that the document is genuine and unchanged — instant trust that raises the firm's standing and removes the need for checking calls.
What they ask about Legal professionals.
Because it is the highest level of legal standing for an electronic signature, and it is created with a token the signer holds themselves, carrying a digital certificate from a licensed certification authority they deal with directly — we do not issue that certificate; we embed their signature in the file and preserve it. The highest we offer by ourselves is the advanced signature (AES) with identity verification, which is enough for most transactions.
Each party verifies their identity before signing with an official document and a live face match, and every event is time-logged in a unified audit trail. We compute a digital fingerprint for the signed document (HMAC-SHA256 for platform contracts, SHA-256 for uploaded PDFs), so any later modification breaks it and the verification page reveals it. The public verification page attests to the document's integrity and its signers' identities.
You set the parties to the document and the order in which they sign. The system sends the invitations in sequence, tracks each signature live, and notifies the next party as soon as the one before them is done. Everyone signs a single trusted copy remotely with no files passed around by hand, so version chaos disappears and the document is concluded in days rather than weeks.
PAdES is the signing standard for PDF documents, and LTA is its highest level for long-term archiving. When signing with a token, the document embeds trusted timestamps and revocation data, so the signature stays verifiable for many years, even after the original certificates expire. Exactly what files that may be opened years from now need.
Yes. Law firms and legal departments use it for their own work: engagement letters, non-disclosure agreements and supplier contracts. They also run it on behalf of their clients to sign powers of attorney, settlements and agreements. One flow serves the firm and its clients with the highest legal standing, with no separate tools.
Every signed document has a public verification link showing the signing status, the parties' identities and the integrity of the copy. The client or any receiving body opens it and confirms the document is genuine in seconds, without checking with the firm. Instant reassurance that spares your team repeated verification calls.
