My question is: is it worth it to hire a lawyer for the divorce process. He left me and my son homeless after a marriage of 4 years.
If lawyers were free, then of course every person going through a divorce should have one. In your situation, even though it is only a four-year marriage, you will have custody issues, child support issues, division of property issues, division of debt issues, and spousal maintenance issues. I have little doubt in my mind that you would be better off if you had an attorney representing you on each of these issues.
Please come in soon. We can certainly help you consider and then pursue your options. This is obviously a very important matter, and you should not go in alone.
