I've been served with divorce papers. My wife's attorney says he can handle everything for both of us. This is particularly relevant in child custody issues. Even if you have no disputes between you as to what is to be done, an experienced domestic relations attorney can be sure to draft an agreement that will do exactly what you both want. Also, keep in mind that an attorney cannot represent both sides of the same case, so your wife's attorney should advise that you hire another attorney to review any documents drafted.
Physical custody refers simply to the allocation of physical time between the parents.
Legal custody refers to the authority to make important decisions regarding the child's health, education and welfare. I don't have the money for legal fees. There is no easy answer. Unfortunately, for dads it is often the case that simply asking for equal parenting time results in expensive custody litigation. You might also consider a loan from a lending institution rather than trying to get an attorney to arrange payments.
