Updated July 28, 2026. Quick answer: A qualified disclaimer must generally be in writing within nine months of the death and made before you accept any benefit from the account. You cannot choose who receives it instead — it passes as if you had predeceased.
The two conditions people break
- Nine months. From the date of death, not from when you found out about the account.
- No acceptance of any benefit. Taking a single distribution, or in some circumstances directing the investments, can void the disclaimer entirely. Do nothing with the account while you are considering this.
You do not get to say where it goes
A disclaimer is a refusal, not a redirection. The account passes to the contingent beneficiary, or under the account’s default terms, exactly as if you had died first. If that destination is not where you want it, disclaiming is the wrong tool.
Which makes the first step establishing who is next in line. If there is no contingent beneficiary, a disclaimer can push the account to the estate — generally the worst outcome available, and the opposite of what a disclaimer is usually trying to achieve.
When it genuinely helps
Where the contingent beneficiary is in a much lower bracket, where you do not need the money and the next generation does, or where estate-tax planning makes passing it down cleaner. It is a real tool with a hard deadline and no undo.
