Standard Form 3110 (SF 3110): Former Spouse's Consent to FERS Election
Standard Form 3110 (SF 3110), Former Spouse's Consent to FERS Election, is the form on which a former spouse consents to a federal employee's election of coverage under the Federal Employees Retirement System (FERS). It is an Office of Personnel Management (OPM) form, Standard Form 3110 (6-90), under 5 CFR 846, formerly OPM 1556. GSA hosts a copy in its forms library.
The form says that if a qualifying court order on file with OPM awards a portion of the employee's annuity, or a survivor annuity, to a former spouse who has not remarried before reaching age 55, the employee cannot elect FERS unless that former spouse consents. The employee completes Part 1, the former spouse completes Part 2 before a Notary Public or other person authorized to administer oaths, and that person completes Part 3.
The completed form is attached to the employee's election, Standard Form 3109. You can fill it out free in your browser on this page and download the result without an account.

Where it goes and what the form says
Where it goes
The PDF gives no mailing address for the form. It is attached to the employee's Standard Form 3109 and filed with it as a permanent document in the OPF.
When consent is not needed
The form lists these cases: no qualifying court order on file at OPM, legal separation without a final divorce decree, a former spouse who remarried before reaching age 55 after the divorce, or staying in CSRS.
If consent cannot be obtained
The form says the employee may ask OPM for a waiver of the consent requirement if the former spouse cannot be located, or for more time to get the court order modified, using Standard Form 3111.
Thrift Savings Plan court orders
The form says a court order for Thrift Savings Plan benefits has to say it applies to the TSP and be filed with the Federal Retirement Thrift Investment Board, Ben Franklin Station, P.O. Box 511, Washington, D.C. 20044.
Privacy
Collection is authorized by Public Law 99-335. The form says furnishing the Social Security Number is voluntary, but failure to do so may mean the election of FERS coverage cannot become effective.

Questions about Form SF3110
Who issues SF 3110?
It is an Office of Personnel Management form: the footer reads Standard Form 3110 (6-90), formerly OPM 1556, 5 CFR 846. GSA hosts a copy in its forms library.
Does SF 3110 need a notary?
The form says Part 2 is completed in the presence of a Notary Public or other person authorized to administer oaths, who then completes Part 3.
Can the former spouse take back the consent?
The Part 2 statement says the former spouse understands the consent is final (not revocable).
Does the court order on file have to be changed?
The note for the former spouse says a modification of the court order now on file at OPM is not required if the employee changes to FERS. Its terms are applied to FERS Basic Benefits, but the amount paid cannot exceed the amount payable under FERS.
What if the former spouse cannot be found?
The form says the employee may ask OPM to waive the consent requirement if the former spouse's location cannot be determined, and points to Standard Form 3111 for how to make that request.
What does the form tell the former spouse about benefits?
It says a FERS basic annuity is generally smaller than a CSRS annuity, and that a FERS survivor annuity for a former spouse cannot normally exceed 50% of the employee's annuity, compared with up to 55% under CSRS.
