You indicate the non-custodial parent is claiming disability but has not filed for it. I don't think you can file for him. I don't do child support but you should look into pursuing him for child support. This may caused him to file for Social Security Disability. He cannot get out of that child support obligation by just claiming he is disabled. If he is awarded disability, then you could receive a check for the child as the custodial parent.
Often a work injury is also a personal injury. However, the workers' compensation may bar you from filing a personal injury. Also, any recovery you receive from the workers' compensation claim may be a lien on your personal injury claim. This is often very complicated so often it can make sense to have the same attorney handle both claims. I suggest you discuss these issues with your current attorney. I practice law in Virginia and the workers' compensation is different in every state.
Your Social Security Disability benefits are based on your wage history and they are not affected by other income or assets that you have. If you have service related VA benefits, they would not be affected by other income or assets that you may have.
When the issue is a mental disability, a lay witness can be very helpful. Even if the witness is on disability is or herself, he or she can testify. His or her disability status does not have to be disclosed unless a question is asked about it. Talk to your attorney about this.
Depending on the office, in my experience it can take 30-90 days before you receive your decision.
If money is being deduced from your check, it may be for an overpayment of benefits in the past. I suggest you make an appointment at the local Social Security office and obtain an explanation. You can also contact your Congressman and if they have a Social Security troubleshooter on staff they may be willing to assist you.
Social Security benefits are exempt from garnishment. However, you need to find out if your pension is exempt from garnishment. Also, if you mingle the two benefits together in the same account you may lose the Social Security exemption.
If you have been awarded SSDI, then you also should receive auxiliary benefits for your minor children. However, you can still pursue your husband for child support for the children. Usually, the obligation to pay child support ends when the child reaches the age of 18. Of course, hindsight is foresight. You should have filed for child support from him long ago. I don't think the courts will award retroactive child support but you should ask when you go to court and file for the child support.
I agree with my colleagues. You just have to wait for the decision by the judge. Hopefully, your attorney was right and it went in your favor. Of course, you can ask "your attorney" questions about your case that is why you hired the attorney.
If the employer does not report his accident to the Virginia Workers Compensation Commission, then he should call the Commission and file his own claim. The number is 1-877-664-2566. Hopefully, the employer will report the accident to his workers compensation carrier and the carrier will provide your boyfriend a doctor and compensation when he is out of work. if this is a serious back injury that incapacitates your boyfriend for a lengthy period then he should consult a workers compensation attorney.
