You can, only if discharged from your Trust Deed, explore other solutions that you feel may benefit your circumstances better at that point such as Minimal Asset Process bankruptcy.
Again, it comes down to what suits you best based on your own personal circumstances and the reasons you're looking to be discharged from the Trust Deed. It may not be easy to get yourself discharged from a Trust Deed depending on your Trustee's interpretation - ultimately you've made a commitment to resolve your debts using a formal solution, which is unlike a utility bill arrangement for example where you simply just cancel one provider and switch to another.
It is in both your own and your Trustees interest to find an amicable solution and should you be worried about your ability to repay your debts then you should speak to your current Trustee as soon as possible, and find out what options they are willing to offer you.
This is another reason why it's best to get qualified debt advice from a leading debt company that is regulated and authorised by the FCA, such as Trust Deed Scotland where we will always work with you to provide you with balanced, expert advice that results in you understanding the solutions being offered to you and how they will impact your financial future.
