Frequently Asked Questions
How much does a military attorney cost?
The cost of hiring a military attorney varies depending on the case and its complexity.

Hiring us at initial stages is not only a sensible strategy but also a sound financial one. Our fee structure is consistent with our focus: to do right by our clients and protect their future.

Can active-duty military personnel hire civilian lawyers as their attorneys?
Yes, both uniformed personnel and DOD civilians can engage civilian lawyers for their legal needs. Selecting the right private counsel is a critical choice. Most law firms have little to no knowledge about the complex, specialized systems and rules of the military. Sean Mangan is a notably qualified attorney in this field, bringing extensive knowledge and abilities to aid those in need of military legal representation. Mangan Law is dedicated to representing service members and DOD civilians, successfully assisting over 200 clients. A dedicated advocate, Sean Mangan reserves his skills and services exclusively for those who serve.
How is military law different than civilian law?
The military has its own complete legal system, including a full criminal court system governed by the UCMJ and several complex administrative systems, all of which can impact the lives of those who work for the military. Many of the rights and protections that the average person enjoys are absent or differently applied in the military setting. For example, rights related to search & seizure and non-incrimination are unique to military personnel, even for acts committed off-base or off-duty. Punishments under the UCMJ tend to be harsher, with a broader range of crimes potentially resulting in life imprisonment or the death penalty. Military trials, or "courts-martial" involve a unique procedure, rules, and standards. Likewise, the administrative systems that regulate military employment and uniformed service have their own, complex rules and can deliver adverse actions that carry lifelong consequences.
What are the rights of service members under military law?
Contrary to the common belief that military enlistment forfeits various Constitutional rights, service members do enjoy several key protections. However, the rules and procedures involved can be very different from that of civilian jurisdictions. Understanding your rights and knowing how to exercise them is is essential when facing adverse action or criminal investigation. Hiring an experienced military law practitioner is one of the best ways to safeguard your rights while defending this nation. Sean Mangan has worked every aspect of the military legal process, and uniquely benefits from his additional experience in civilian courts and law enforcement. At Mangan Law, we know the process inside and out and will leverage that knowledge to protect our clients and their interests.
