One lease.
10 signatures. Every delay costs you rent
Commercial leases, addendums, rent reviews, service contracts, and handover protocols routinely need 5–10 signatures from different people, across different companies and locations – and tenants’ legal and finance teams require QES-level validity. 4SIGNER coordinates every signature in one tracked flow, so one slow signer never pushes your lease start date back by weeks.
CERTIFIED BY
A lease isn't binding until everyone signs.
And someone always hasn't
Commercial property runs on a constant flow of documents – lease agreements, addendums, rent reviews, service contracts, handover protocols. None of them involves just two people. A single commercial lease can need 5 to 10 signatures from different individuals, across different companies, in different offices and cities.
Your tenants are businesses. Their legal teams, finance teams, and signatories all have to review and sign, and they expect QES-level legal validity before they’ll commit. Coordinating that on paper or by email means printing, posting, chasing, and waiting on whoever is slowest.
And here’s where it actually hurts: the lease isn’t binding until the last signature lands. One delayed signature from a tenant’s legal team can push the lease start date back by weeks, and every one of those weeks is rent you’re not collecting on space that’s sitting empty. The cost of a slow signer is measured in real money.
There is a better way.
Every signer, in one tracked flow
Send the document to all parties at once or in sequence – your team, the tenant’s signatories, their legal and finance contacts – each signing with a fully qualified electronic signature, legally equivalent to a handwritten one and valid across all 27 EU member states. You see in real time who has signed and who hasn’t, and a reminder is one click away. No guessing where the lease is stuck.

You probably have
a few questions
Is an electronic signature legally valid for commercial lease agreements?
Yes. Qualified electronic signatures issued by 4SIGNER are fully legally valid under the eIDAS regulation, equivalent to a handwritten signature, and accepted in all 27 EU member states including Slovakia and the Czech Republic.
Can a single document be signed by multiple parties from different companies?
Yes. Send a lease to all signatories at once or in a set order – your team, the tenant, their legal and finance contacts, and track every signature in real time, wherever each person is based.
Will a tenant's legal and finance team accept the signature's validity?
Yes. 4SIGNER provides Qualified Electronic Signatures – the highest legal tier under eIDAS, equivalent to a handwritten signature and enforceable across the EU. It’s precisely the standard sophisticated B2B counterparties require.
How do I know where a lease is stuck?
You see live status for every signer and can send a reminder with one click. No more emailing around to find out who hasn’t signed and why the lease isn’t binding yet.
How is 4SIGNER different from DocuSign or Autenti?
4SIGNER provides Qualified Electronic Signatures as standard – the court-proof legal tier most platforms treat as an add-on or omit entirely. For multi-party commercial leases where every counterparty’s legal team must be satisfied, that built-in validity is exactly what closes the deal faster.
