No. DAS; the Debt Arrangement Scheme (DAS) is not a type of Bankruptcy (Sequestration in Scotland) it is instead a structured, formal debt repayment plan for residents of Scotland.
Insolvency solutions including Protected Trust Deeds may usually allow for a percentage of the original debt to be written off but this should not be the only deciding factor in your decision. Additionally, you not always be eligible for those solutions.
A DPP will last until all debts are repaid. Entering into a DAS won’t affect your home or mortgage providing you keep up with the repayments of your rent/mortgage, which is separate from your DAS repayments.
However, as the Debt Payment Programme (DPP) is agreed using your true affordability then you will have enough budget to pay both your new, reduced contribution to your debts and your more important bills known as priority debts. These priority bills include things like your rent and mortgage and other bills such as utility bills and council tax.
