Many New York parents consider adding an adult child to their bank account as a way to simplify bill paying or ensure someone can access funds in an emergency. While this can be convenient, it also carries risks that are often overlooked. ## What Happens When You Add a Joint Owner When you add your adult child as a joint owner on a bank account, they generally gain full legal ownership rights to the funds — not just access. This means the funds are subject to their creditors, divorce proceedings, and legal judgments. ## Estate Planning Implications Joint accounts typically pass directly to the surviving joint owner outside of probate, regardless of what your will says. This can unintentionally disinherit other family members if not carefully coordinated with your overall estate plan. ## Alternatives to Consider - **Power of Attorney** — Grants your child authority to manage the account without giving them ownership. - **Convenience accounts** — Some banks offer designated "convenience signer" arrangements that avoid ownership issues. - **Revocable trusts** — Can provide more control and flexibility for larger estates. ## Talk to an Attorney First Before adding a family member to your accounts, it's worth discussing your goals with an estate planning attorney to make sure the approach fits into your broader plan.
