Legal Department

The County Legal Department provides a diverse range of legal services for the government of Doña Ana County. The department is staffed by three attorneys, three paralegals, and one secretary.

The Legal Department provides legal advice to the Board of County Commissioners, the County Manager, the Sheriff, the Assessor, the County Clerk, the Treasurer, the Probate Judge and appointed commissions such as the Planning and Zoning Commission and the Extraterritorial Zoning Commission, and advisory boards such as the Health Advisory Council and the DWI Advisory Board. The Legal Department also advises the directors and staffs of all departments within the county government.

The attorneys attend many internal and public meetings, perform legal research, draft legal opinions and documents, negotiate on the county's behalf, and represent the county in court and administrative hearings.
