Delegated Account Access: How Brokers Handle Authorization

Delegated Account Access: How Brokers Handle Authorization

Many retail investors need to grant account access to a trusted person—a family member, financial advisor, or estate executor. Understanding how brokers handle delegated access protects both your account and theirs. Here's what you should know.

What Is Delegated Account Access?

Delegated account access means authorizing a person or entity to act on your behalf with certain permissions—such as trading, withdrawing, or handling transactions—under a formal arrangement like a durable power of attorney or as an agent. Critically, giving someone account access doesn't transfer ownership of the account; you remain the sole owner, responsible for any taxes or debts on the account.

Account Type Matters

Not all account types use the same authorization process. For personal accounts (like an individual brokerage account), you can grant someone access online, but fiduciary accounts (like organizational or trust accounts) require a paper or digital form. This distinction exists because fiduciary accounts—those held in trust or for an organization—involve legal duties that brokers verify through signed documentation.

Regulatory Requirements for Brokers

Brokers don't have complete freedom in how they set up delegated access. FINRA Rule 3110 specifically requires firms to adopt procedures concerning transmittals of customer funds that include a means of customer confirmation. This means your broker must confirm that delegated transactions are genuinely authorized—not the result of fraud or a breached password.

Brokers also face liability if they fail to verify delegation properly. When delegation is formalized (such as through power of attorney), brokers typically require documentation before granting access to prevent unauthorized trading.

What Permissions Can You Grant?

Most brokers allow you to set granular permissions. A delegate can typically be granted the ability to: - View account balances and positions - Execute trades - Withdraw funds - All of the above, or a limited subset

Some brokers allow you to set expiration dates on delegated access—automatically revoking permission after a specified period unless renewed.

Security and Your Responsibility

Granting account access is a significant trust decision. A custodial or inherited account may require extra care because access questions can become more complicated when family members, beneficiaries, or legal documents are involved. Before granting access, verify that the delegate understands their role and that you have a signed, documented agreement in place.

If you use delegated access, confirm regularly that your broker supports two-signature requirements or additional authorization steps for large transactions—useful protections whether the delegate is family or a professional advisor.

When to Use Delegated Access

Common scenarios include: - Granting a spouse access to manage household investments - Authorizing a financial advisor to trade on your behalf under a written agreement - Enabling an executor or trustee to manage accounts during estate settlement - Allowing an adult child to assist an aging parent with account management

In each case, documentation and clear permission boundaries reduce risk for everyone involved.

The Bottom Line

Delegated account access is a normal, regulated feature, but setup matters. Your broker will likely require signed forms for fiduciary or formally delegated access, and regulatory rules ensure that unauthorized changes are harder to execute. Verify your broker's specific process, set clear expiration dates if available, and keep documentation of any delegation you authorize.
