41 CFR § 302-3.202
If my immediate family member and I both transfer to the same official station, may we both claim the same relocation allowances for the same non-employee family member?
June 9, 2020
No, when both you and your immediate family member transfer in the interest of the Government, you must provide your agency with the name(s) of non-employee family member(s) who will receive allowances under each of your TA. Only one of you may claim allowances for a non-employee member(s) of your immediate family (non-employee members may only be on one TA).
