The secure client portal of gross::rechtsanwaelte.
Kleos Connect is our firm's digital client portal. Through an encrypted, GDPR-compliant platform you can follow the status of your matter, access briefs and documents and communicate securely with us – no unencrypted e-mails, no postal delays. Your file is available to you at any time, from anywhere, in one protected place.
Once we have accepted your mandate, we create your file in Kleos Connect and share it with you specifically. You will then automatically receive your personal invitation link by e-mail. If you previously used the WebAkte, just let us know – we will activate your Kleos Connect file for you.
sign-in
Four steps to your digital file – once set up, logging in takes just a few seconds.
You receive an e-mail with your personal invitation link – the sender is “Kleos Connect”.
Open the link, confirm your e-mail address and choose your own secure password.
From then on simply use the login button – with your e-mail address and your password.
View and download documents, upload your own files securely.
help
The most common questions – and how to solve them in a minute.
Please check your spam or junk folder first – the invitation comes from the sender “Kleos Connect” (kleosapp.com), not from our firm's address.
Nothing there? Then give us a quick call or write to us – we will check that your e-mail address is on file correctly and resend the invitation.
For security reasons, invitation links are valid for a limited time. If yours has expired, we will gladly send you a new one – a short call is all it takes.
If you have already registered before, you no longer need the invitation link: simply sign in via the login button. You can reach the login page at any time at connect.kleosapp.com
Open the invitation link from the e-mail and register with exactly the e-mail address the invitation was sent to – a different address will not work.
Then choose your own secure password and keep it safe. From now on you sign in with it at any time via the login button.
On the login page, click “Forgot password”. You will receive an e-mail to reset it (please check your spam folder here as well).
For your security: only you know your password – we cannot see it either, we can only trigger the reset.
Please check that you are signed in with the invited e-mail address – your file is shared for this address only.
It is also possible that your file has not been fully shared yet. A short message to us is enough – we will check the sharing right away.
Reload the page once and use an up-to-date browser (Safari, Chrome, Firefox or Edge). Switching to another device – from phone to computer, for instance – sometimes helps too.
Please allow cookies for connect.kleosapp.com – signing in is not possible without them. If the problem persists, we will help you by phone.
Still stuck? Just call us: +49 341 98462-0 (Mon–Fri) or write to leipzig@advo-gross.de – we will set up your access together with you.
