An estimated one-fourth of guardians for aged and disabled adults are corporate employees, or other professionals or practitioners, rather than family members. Many are lawyers, who may practice individually, in limited-liability corporations, or in partnerships. Non-lawyers also may establish guardianship practices. Some are social workers or accountants by profession, but most states require no such professional affiliation. In addition, states now provide public-guardian services for those who have no voluntary assistance and cannot pay. Any guardianship organization may utilize volunteers to provide services to individual wards, and then the volunteers become the agents of the organization.
