A child’s 18th birthday is usually celebrated as a milestone toward independence, but for families raising a child with disabilities, it can also trigger major financial and legal changes.

Savings, inheritances and even well-intentioned gifts can also create unexpected complications. That is why disability financial planning deserves attention before the candles are blown out.
