The main difference between a $2503($b$)$ and a $2503($c$)$ trust is:

The trustee of a $2503($b$)$ trust must distribute the principal of the trust within five years of

the beneficiary reaching the age of majority. With a $2503($c$)$ trust the trustee must

distribute the principal of the trust at the death of the beneficiary.

The $2503($c$)$ trust only allows distributions for the health, education, maintenance, and

support of the beneficiary.

The $2503($b$)$ trust requires the trustee to accumulate income, whereas the $2503($c$)$ trust

requires the trustee to distribute all income.

The $2503($c$)$ trust must terminate, or the beneficiary must have the right to receive the

trust's assets, when the beneficiary reaches age $21.$ A $2503($b$)$ trust may hold propertic for

the lifetime of the beneficiary.
