If you are starting a business in the DR it is highly recommended that you get a competent lawyer. You can attempt to get through the process alone, but at the end of the day a good lawyer can save you time and the hassel of doing all the paperwork. Also, a good lawyer can answer any questions you have and can reduce the number of mistakes you make as you begin the business process.
If you are moving to the DR a lawyer is also recommended. A lawyer would be a good contact to have as you begin the moving process and can also help you as you purchase a car, a house, or getting shipped goods out of customs. Lawyers can also help you with getting your cedula identity card or any other immigration related papers.
