Client access is issued to invited users and authorised representatives. There is no public registration flow. If you have not received access through an established relationship, use the introduction process rather than attempting to create an account from a third-party link.
If you cannot sign in
Check that you are on montclairbellerive.com and use the client sign-in page. Enter the email address associated with your access. Check typing, keyboard language and whether a password manager has selected an old entry. The show-password control can help on a private screen; avoid using it where someone else can see.
Do not repeatedly guess a password. If you remain unable to sign in, contact your relationship team using details previously supplied through a verified channel. Ask for an access review. This website does not provide a public self-service password reset, and your contact should not ask you to send your existing password.
An expired or invalid invitation
An onboarding link is single-use and expires. A message that the link is invalid can mean it is incomplete, expired, replaced or already used. Ask the person who arranged your access for a fresh invitation through the established channel. Do not forward the link to another person.
Use the complete link supplied to you. If an email client has broken it across lines, return to the original message rather than trying guessed variations. After successful activation, use the normal sign-in page for later visits.
Browser and session issues
Allow the functional session cookie required by the portal. If the page is not responding, reload once and check your connection. Before clearing site data, understand that this may remove local preferences and sign you out. It will not remove the official account records held by the service.
On a shared device, close the session by signing out. Do not provide remote access to your device in response to an unsolicited support call. Avoid sending screenshots containing account details, session tokens or other confidential information through an unverified channel.
A representative needs access
Each authorised person should have access appropriate to their role. Ask your relationship team to review the representative and required authority. Sharing your own password prevents a clear record of who acted and is not a substitute for establishing authorised access.
If access may be compromised
Stop responding to the suspicious communication and contact your relationship team through a previously verified route. Explain whether credentials were entered, a payment was instructed or a device was accessed. Ask for urgent review of access and affected instructions. Read the fraud-response guidance for the information to preserve.
If there is an immediate risk and you cannot reach your usual contact, use the alternative contact already supplied in your relationship documents and report the incident to the appropriate local authorities where necessary. Do not use a replacement number supplied by the suspected sender.
What to include in an access enquiry
- Your name and the email address associated with access.
- A brief description of the step that failed and the time it occurred.
- The visible error wording, without confidential account data.
- Whether the issue concerns an invitation, sign-in or suspected compromise.
Never include your password, a one-time code, a full invitation link or browser session values. Your identity may need to be checked through the agreed process before access can be changed.
