How can a law student get prenuptial agreements and children custody legal experience?
No lawyer or firm is going to practice only in the areas of prenuptial agreements and child custody. You will need to look for experience in the more broad area of family law. I clerked at a small private firm in the summer after 1L. I had to volunteer my time. I had two subsequent internships at public interest law firms (legal aid and one other.) Legal Aid does a lot of family law, and the offices near me are often looking for law student volunteers. After law school graduation, I found my first job practicing juvenile law on my law school job listings. I wanted to practice family law, but the job market was tough and I didn’t have any opportunities in that practice area. I practiced juvenile law for a year, while networking in the legal community, and then landed a job at a family law firm.
