She joined campaigners at the House of Commons on Wednesday at a meeting organised by parent campaigner Andrew Turner, charity Contact and a financial services provider.
Andrew Turner from Horsham, West Sussex, whose 23-year-old son Mikey has a rare degenerative condition, said Junior ISA’s were also affected.
He said many parents were “totally confused by the whole situation and it’s completely unfair”.
Andrew said he wanted the government to create one simple, accessible system for parents to prove their circumstances and access money on behalf of their child.
He added the Mental Capacity Act was important, but “sending parents through a very complex and expensive court process simply isn’t working.”
In a statement, the government said: “We understand the difficulties parents of disabled children can face when seeking access to a Child Trust Fund once their child has reached adulthood.
“That’s why we have digitised the application process and created a step-by-step guide to help parents through a system that exists to protect funds from fraud and abuse – and we are continuing to work across government to find ways to make it even easier for families to access these funds.”
