GEnerally speaking if one is a benificiary of a trust and has access to the funds that's a killer for many means tested programs including student financial aid...the level of impact varies ...IF you pass....a future expectation is not a countable asset under FAFSA .
However there may be ways to structure giving them money for education with less of an impact against public sector aid under FAFSA ...for example 529 plans are counted differently . And due to some counterintuitive rules you could set up and fund 529s now , give them nothing in trust , and yet dip in yourself to the 529 is you so need ..with but a small penality on just the earnings component.
