If someone you know with special needs receives money from an inheritance, lawsuit, or another source, you will want to set up a Special Needs Trust. You do not want these funds to affect the benefits they receive from the Social Security Disability (SSI), Medicaid, or housing support (HUD). This type of Trust would be called a First Party Trust. When you create this Trust, they will still receive their benefits and will have access to the funds for any supplemental needs.
