First, you need to ensure that the lawyer you are hiring is familiar with the domestic laws regarding divorce and child custody. This can be determined by their level of professional training. Such details are usually available on the website of the law firm for which a particular lawyer works. Ensure that you investigate to find out more about their training, the schools they went to, and if they completed. Besides, a legitimate lawyer should be registered and have a license to provide legal services in your area. This way, you will be sure that they understand the legal system and can provide the best services. At the same time, a local lawyer is deemed better considering that they understand the local laws.
