How to Choose the Right Form
Selecting the right joint account form depends on your specific financial institution and whether you are setting up a new account, modifying an existing one, or adding specialized features like investment permissions.
Adding a Co-Owner or Changing Account Type
If you already have an account and want to add a spouse or partner, or if you need to convert an individual account into a joint one, look for registration-specific forms:
- Navy Federal Change of Information/Add Joint Owner: Use this if you are a credit union member (18+) looking to update personal details or add a secondary owner to your existing Navy Federal accounts.
- Fidelity Change of Account Registration: Choose this form to transition a Fidelity brokerage account between Individual, Joint, or Custodial (UGMA/UTMA) statuses, or to add/remove owners from a non-retirement account.
Defining Legal Ownership and Rules
When opening a new brokerage account or formalizing how assets are managed between two people, you need a legal framework for the partnership:
- Joint Account Agreement - Merrill Lynch: This is the primary document for Merrill Lynch clients to define ownership types (such as Joint Tenants with Rights of Survivorship) and establish who is authorized to execute transactions.
Estate Planning and Beneficiaries
To ensure your joint assets pass directly to heirs without going through the probate process, you must designate specific beneficiaries:
- TIAA Brokerage Joint Transfer on Death Account Agreement: Use this for TIAA accounts to name primary and contingent beneficiaries. This ensures that assets are transferred directly to your loved ones upon the death of the last surviving account owner.
Specialized Trading Permissions
Joint accounts often require additional disclosures if you plan to engage in advanced investment strategies:
- Option Information — Individual, Joint and Trust Accounts: This form is required for any joint account holders who wish to be approved for options trading. It collects financial data and experience levels for all parties to determine risk suitability.

Tips for joint account forms
Choosing between Joint Tenants with Rights of Survivorship (JTWROS) and Tenants in Common (TIC) is a critical step. JTWROS typically ensures assets pass directly to the survivor, while TIC allows for specific ownership percentages that may pass to heirs, so clarify your preference before starting.
When adding a joint owner, double-check that names, addresses, and Social Security numbers match official government IDs exactly. Discrepancies between the primary and joint owner's data are a leading cause of processing delays or account freezes.
Most financial institutions require copies of government-issued IDs or proof of residency for all account holders listed on the form. Having these digital files ready before you start filling out the PDF will streamline the entire submission process.
AI-powered tools like Instafill.ai can complete these forms in under 30 seconds with high accuracy, and the data stays secure during the process. This is a practical time-saver for people managing multiple registrations or complex brokerage agreements.
Joint account forms often ask whether each owner can act independently or if both signatures are required for transactions. Carefully select the option that fits your partnership's needs to avoid future logistical hurdles when managing or moving funds.
For joint accounts, TOD instructions typically take effect only after the last surviving owner passes away. Be sure to clearly list both primary and contingent beneficiaries to ensure a smooth transition of assets and avoid the probate process.
Joint account forms almost always require signatures from every person being added, removed, or modified on the registration. Ensure all parties are available to sign the document, as missing signatures are the most common reason for form rejection.
Frequently Asked Questions
These forms are used to establish or modify legal ownership of a financial account between two or more individuals. They define how assets are managed, who has the authority to authorize transactions, and how ownership is handled in the event that one account holder passes away.
JTWROS is common for spouses because the surviving owner automatically inherits the deceased owner's share. In contrast, Tenants in Common allows owners to specify a percentage of ownership, and that share becomes part of the deceased owner's estate rather than transferring directly to the other account holder.

Most agreements require the full names, physical addresses, dates of birth, and Social Security numbers for all parties involved. Depending on the institution, you may also need to provide government-issued identification or employment details for the new account holder.

The outcome depends on the ownership type selected during the application process. In a JTWROS account, the assets typically transfer to the surviving owner; in a TIC account, the deceased's share is distributed according to their will or state law.
Adding a minor usually requires a Custodial Account (UGMA/UTMA) registration rather than a standard joint account. Financial institutions provide specific registration forms to handle these cases, ensuring the account is managed by an adult for the benefit of the minor.
Completed forms should be submitted directly to the financial institution that holds the account, such as Fidelity, Merrill Lynch, or Navy Federal. Many institutions allow for secure digital uploads through their member portals, while others may require the forms to be mailed or delivered to a local branch.
