Because you are asking this question under the topic "Social Security Disability" I will assume your fiance needs someone to handle her money. Instead of guardian, the Social Security Administration (SSA) refers to such a person as a representative payee instead of guardian.
There are a series of steps that are required. You can learn all about the process at the website of SSA http://www.ssa.gov/payee/index.htm
