eObig for Real Estate and Realtors: Contracts Online

Leases, guarantees, acts and amendments — sign with a QES online. The other party signs via a link without registration. For agencies, owners, HOAs.

September 8, 2026·7 min read

Real estate is a contract business. Leases, sales, guarantee agreements, handover acts, amendments on price or term — and almost always the parties are in different places. Paper workflow costs the most here: couriers, meetings, lost days and deals that fall through because of signature logistics. eObig removes that friction: everything is signed with a QES online, in minutes and with full legal force. Here is who it helps and how.

Who it fits

  • Realtors and real estate agencies — a steady flow of contracts with owners and tenants.
  • Owners renting out housing or commercial space — arrange a lease quickly without meetings.
  • Property managers and homeowners' associations — contracts with residents and contractors.
  • Developers and brokers — preliminary contracts, reservations, amendments.

Which documents are signed online

A detailed step-by-step scenario is in how to sign a lease agreement online.

Why it works even when the parties are in different cities

The main advantage for real estate is independence from geography. You send the document as a link, and the other party signs with their QES right in the browser. Moreover, the tenant or owner does not need an account — signing via a link without registration removes the main barrier for one-off deals and individual clients. The private key forms the signature locally and is never transmitted (see the security of browser-based signing).

Legal force

A contract signed with a QES has the same force as a paper one with a handwritten signature, and it is accepted by courts and government bodies — more in the legal force of an electronic signature. One exception to remember: a building lease for 3+ years requires notarization; most leases are executed electronically without a notary.

What else eObig gives an agency

  • AI assistant for quickly preparing standard contracts — see AI in document workflow.
  • Archive with search — all deals by property and client in one place (electronic archive).
  • Teamwork — roles for agents, real-time signing statuses.
  • API — embed signing into the agency's own CRM (CRM integration).

In brief

  • Real estate is a contract business with remote parties; a QES saves the most time here.
  • Leases, guarantees, acts and amendments are signed online in minutes with full legal force.
  • The other party signs via a link without registration — even an individual.
  • A notary is needed only in specific cases (a building lease for 3+ years).
