I am an attorney who practices in the Greater Tampa, St. Petersburg, FL area. While I am not familiar with your state's law, states generally have similar statutes.
The following are some of the factors that the courts generally look for:
1. Is the minor financially independent?
2. Does he reside separate from his parents?
3. Is there some defect in the parent/child relationship which would justify emancipating the minor.
There are other factors, but these are the ones that come to mind first.
If the minor legally gets married, then generally the minor will be automatically emancipated. However, a minor usually needs his parents permission to get married.
Is there a pregnancy involved? Many States have statutes which permit pregnant minors, who are close to the age of majority, to get married without their parents' permission. Generally, if you are pregnant, and both parties want to get married, then this is probably the easiest way to get emancipated. However, each State has specific requirements, so check your State's statutes.
A law school's law library is a good place to check your State's statutes. Ask a kind looking libarian for guidance. Make sure you look up the current statute.
You should be neutered if you get pregnant and married just to get an easier way of getting emancipated. Don't be a moron. Besides, it is not a sure thing. In Florida the judge has sole discretion to either grant or deny the petition to permit a pregnant minor to marry. I bet you have a similar rule/statute in your State.
Maybe you will find a lawyer with a soft spot who will be willing to help you for a greatly reduced fee. God knows I've done this many a time for only about 20% of my regular fee plus court costs. Shop around.
You should schedule a formal consultation with a lawyer. A good means of obtaining an attorney referral is by contacting your State's bar association or your local county bar association. They probably have a web site and charge a nominal fee for the referral. Most attorneys either provide a free initial consultation, or charge a nominal fee.
Good Luck.
