There are plenty of parents who receive SSD who have primary custody of their children. The court looks at your ability to care for your children or to provide for adequate care. If your disability is an impediment to caring for your children it will be a factor. Since it does not sound like it is, I would not wait as most SSD claims are denied the first time and it can take awhile to be approved.

You would need to file a Motion asking the Judge to Recuse himself and allege bias. Unfortunately, the trial judge who you are asking to be recused is the same judge that decides if he is biased.

Since you are aware of the proceeding you should go because you could be deemed served even if it is not proper. If it is a Master's conference they may reschedule it if the other side cannot prove service. If they lie, however, it will proceed without you.

Fortunately, there are programs out there that assist children to get aid from schools that she applies to for college. Your daughter should apply and see what kind of aid packages she is offered from college.

In addition you should be getting alimony depending on the length of your marriage provided you do not live with another many. You also can get APL or spousal support while the divorce is pending. In addition, don't forget assets in his name alone are also assets you can get such as retirement accounts, etc.
You need to sign an Affdiavit of Two Year separation and serve it on her with a counteraffidavit. Wait twenty days after service and then if she does not contest you have to file a Praecipe for a Divorce Decree if no issues have been raised. There are some good books in the bookstore with forms if you want to try to do it yourself. If issues such as division of assets or alimony are raised you will need a hearing or an agreement and I would consult counsel.
