There are 58 million Americans five years of age or older that are identified as special needs making them the largest single minority in this country. The majority of federal and state benefits available to help persons with disabilities are needs based, meaning income and assets are strictly limited and can often by misinterpreted, resulting in costly mistakes.

One of the most common mistakes a parent or loved one makes is disinheriting their family member with special needs. The reason is often because the family believes other siblings will step in and take care of the disabled family member. However, this can lead to numerous problems, especially if the non-disabled sibling gets sued, divorced, or otherwise loses the money left to them.

Another common mistake is failing to create a properly drafted trust to qualify the disabled family member for government benefits than can help pay for costly medical and/or living expenses. Qualifications for government benefits like Supplemental Security Income (SSI) or Medicaid dictate that the disabled individual has no more than $2,000 in assets. If your disabled loved one has assets above this threshold, they will have to be "spent down" to qualify for government assistance or otherwise protected in a properly drafted trust.

Well-meaning friends and extended family may not understand the complexity of disability benefits and give a disabled loved one money or assets that would disqualify them for state and federal benefits. It is especially difficult if the disabled person already has benefits and becomes disqualified because the "needs based" review discovered additional funding putting them over the $2,000 asset limit. It is best to avoid this situation as it may be a big hassle to re-qualify the disabled person for government assistance.

Be wary of crowdfunding sites like GoFundMe to benefit your loved one with special needs. In the absence of qualified legal planning, these donations can disqualify SSI, Medicaid, food stamps and section 8 housing. A well-meaning fund campaign could cut the benefits of a disabled person and make their living circumstances worse than before.
