My neighbor's daughter attempted to do so with desastrous results. Her ex showed up with a lawyer. There was something that she wasn't allowed to do because she wasn't a lawyer and therefore the judge couldn't consider it and only considered her ex's side (which was presented by his lawyer). In the end, her ex walked out with joint custody and my neighbor's daughter was ordered to pay child support to HIM.
On the other hand, my husband and his ex didn't even bother the court when they modified the court order concerning child support. They wrote down what they had both agreed to, got their signatures notarized, and that was it. No judge or lawyers were involved. Apparently, when both parties agree, you don't need a judge at all. The court gets involved when there are disputes.
Unfortunatly, best is a relative term and an attorney or firm that one person might believe is the best will not be what the next person thinks is the best. Add the fact that you are seeking a divorce which is an extremely emotional and turbulant time for all involved, and the idea of best can get skewed and mixed up in the emotional battle. In addition, one client's outcome may be exactly the same as another, but client #1 was very satisfied with the court's decision while client #2 was not. It really depends upon your expectations.
It is far better to determine what traits/qualities you are looking for in an attorney. For example, are you seeking a man or a woman attorney and are you seeking an extremely aggressive approach or a bit more laid back? I know the man and woman attorney question may be crazy, but if you are a man whose wife has filed for divorce and the wife is attempting to destroy your character in court, sometimes it can be helpful to have a female attorney to "show" the judge that not all women are "afraid" of you. Of course, this strategy also works the other way around and there are times when having an attorney of either gender may be more preferred in terms of overall strategy.
