The DoD does have methods of deciding whether you can transfer GI Bill benefits to your family.
How do I transfer my GI Bill benefit to my husband?
While you are still on active duty, you will request to transfer, change, or revoke a Transfer or Entitlement TOE through milConnect.  If the DoD approves the TOE, your family members may apply for the benefits.
When will my children be able to use the GI Bill benefits if I transfer them?
Your children will be able to start to use the benefit only after you have finished at least 10 years of service.  They may use the benefit while you are on active duty or after you have separated from service.  However, they may not use teh benefit until they have gotten a high school diploma or equivalency certificate or have reached the age of eighteen.
Can I transfer my GI Bill benefits?
Have you completed at least 6 years of service and do you agree to add four more years of service to your prior time, or have you already completed 10 years of service?
I have not yet reached my 6th year of service.
Are you planning to spend at least ten years in the service?
I am not going to commit to ten years of service until I find out if I can get the training schools I would like.
If you are not going to commit to ten years, your benefits will be yours and yours alone to use.
If I do decide to meet the requirements and want to transfer the benefit to my spouse, when would he be able to use it?
