Nursing Homes and Assisted Living Facilities are completely different.
Nursing homes provide medical care as a primary service.
Assisted Living is primarily a residential service with some additional personal and low level medical services. A Nursing Home must have a written contract with everyone who is admitted. See this Maryland State Bar Association brochure on what to look for in the contract. Legal Assistance for Nursing Home residents - the Legal Aid Bureau has a unit that provides legal assistance to nursing home residents anywhere in Maryland. You may file your complaint anonymously.
